Muffler for a chainsaw: how to make the tool silent?

A chainsaw is one of the common tools used for cutting trees and large shrubs. And if there are ways to protect your eyes and face from small flying chips, then what to do with your ears? A running chainsaw is very loud and can damage your ears even if used briefly. Especially if it is a gas chainsaw. To help you work more safely with this tool, we suggest you make your own chainsaw muffler using the guide we provide below.

Possible inconveniences associated with a quiet muffler

The car will now be quieter, which is what we wanted to achieve, but there may be some disadvantages - an increase in the overall weight of the exhaust system.
Therefore, it is necessary to hang stronger brackets so that the exhaust pipe does not come off on rough roads. There are also cases when rubber shock absorbers are hung. But in fact, a homemade resonator will weigh about 2-3 kg. It is also necessary to test in action how the exhaust system works so that gases exit normally through the exhaust pipe. Therefore, it is necessary to check at higher speeds, then it will be possible to draw the right conclusions. But as a rule, gases will escape through such a resonator without difficulty.

And then in the video there is another way to reduce the sound of the muffler, making a really very quiet exhaust system:

Ruslan, reducing the exhaust volume, strengthening the muffler, you will lose power.

Zhanna a customer comes to the store to return an item - a chainsaw. - what are the complaints? - yes, in the instructions it says that it cuts 4 cubes of firewood in an hour, but I can’t do more than 3 - let’s check in a minute Peter - wow, why is it whirring for you?

Why does a chainsaw make noise?

There are a few different reasons why chainsaws are so loud. These 3 factors create the most noise:

• engine/motor;
• sawing;
• vibrations.

You've probably already guessed that the engine is the main culprit behind the noise. This is why gas chainsaws are so loud compared to others, as their engines produce the most noise on average.

The cutting process will also add to the noise produced by the chainsaw. A chainsaw with an old chain that is no longer sharp and is not properly lubricated can potentially result in higher noise levels.

Vibrations, although to a much lesser extent, will also increase the overall noise level. One of the reasons electric and cordless chainsaws are much quieter is that they will generate less vibration.

Why do you need a muffler?

Prolonged exposure to extremely loud noises is undoubtedly dangerous and can lead to hearing loss. Chainsaws can be very loud, ranging from 80 to 120 decibels. For comparison, a normal conversation averages about 60 decibels.

The longer and more often you expose yourself to loud noises, and the closer you are to the source, the more damage your hearing will suffer.

Let's look at some data and time frames:

1. Sounds up to 70 dB are safe and you can listen to them for extended periods of time.
2. Sounds at 85 dB are dangerous if you listen to them for more than 8 hours.
3. Sounds at 111 dB are extremely dangerous and can cause hearing loss in less than a minute.
4. Sounds around 200 dB are fatal.

Interestingly, the loud noise from chainsaws isn't just dangerous to your ears. Loud noises pose even greater health risks. They can lead to:

• upset stomach;
• high blood pressure;
• increase in heart rate.

After using a chainsaw for a short period of time, you may need to take at least an 18-hour break to allow your hearing to recover.

Check the ignition coil on a chainsaw

If preliminary actions did not help in identifying the cause of the chainsaw malfunction, then it is necessary to check the ignition coil of the saw. Diagnostics is performed in several stages:

1. Measure the coil resistance using a multimeter. To do this, you should know the optimal parameters, which are indicated in the operating instructions. However, due to the use of semiconductor elements in the system, if you try to “ring” the coil, the result will be an “Open Circuit” reading. This is fine. A sign of a malfunction is a positive test result. That is, if it was possible to determine the resistance of the coil using a special tool, then it is definitely faulty.
2. Check for spark with a special device. This device should be installed in the open circuit located between the spark plug and the high-voltage terminal of the saw's ignition coil. The indicators will be visible on the display. This verification method is more often used in service centers, since the device required for this is expensive, and the costs will not be comparable to the benefits provided.
3. Testing the coil using a spark plug, i.e. perform a homemade ignition. To do this, you need to unscrew it, and then attach the body to the cylinder. Now you need to pull the starter and watch for a spark. But this method only gives an approximate result, since the flywheel spins faster due to the unnatural position of the spark plug.

If none of these methods work, or if you need to check in the field, you can proceed as follows:

1. Remove the cap from the candle, insert a nail without a head into the core at a distance of 6-7 mm from the cylinder. This must be done as carefully as possible so as not to damage the part.
2. Perform the steps required to wind the tool. Now you need to look at the presence of a spark and its color. If there is no malfunction, the spark will be strong and the color will be bright blue.

This method can be used as a last resort and only if there are no electronic components, but it is important to follow the rules:

• Do not completely unscrew the spark plug, as this may cause the flywheel to rotate faster, which is not the correct engine operating mode;
• it must be located at a distance that corresponds to the compression model and dielectric properties of the fuel mixture, so this parameter can be found in the instructions (the value of 6-7 mm is average).

What can be made from a chainsaw: basic accessories for chainsaws that have gained popularity

If you purchase special attachments for the tool, it will be extremely easy to install them; you won’t need to modify anything or disassemble the tool body. All ready-made accessories are designed specifically for installation on a chainsaw. Another important advantage of purchasing a chainsaw is its autonomy. This is explained by the fact that all electrical devices require a 220 V outlet. Using a chainsaw, you will be able to use homemade products in the field, be it a drill, an ice drill or a wood cutter.

A self-installed grinder attachment on a chainsaw allows you to use the equipment not only as a gas cutter, but also as an angle grinder. The nozzle is connected to the device via a special pin, and begins to rotate using a belt from a pulley attached to the drive sprocket shaft. Thus, the device is installed instead of the saw bar

It is important to choose the correct diameter of the nozzle circle; to do this, you must first study the instructions for the Druzhba chainsaw or other equipment used to make a useful device

Note! Experts warn that it is not possible to install an adapter in all models to fit the bases. The cutter is one of the most popular chainsaw attachments. Another popular attachment among users is a corroder, used for cutting bark from trees.

The attachment is also popular among woodworkers because it can be used to easily remove bark, knots and growths from untreated wood. Some use a nozzle to create longitudinal or transverse grooves on the beam

There are mainly two types of coders:

1. Drums. The main area of ​​application is bark removal, the second name is decanter.
2. Disk. Used to create various types of recesses.

There are several nozzles on sale that differ in grip width, most often 80 and 100 mm. If the knives become dull, there is the possibility of secondary sharpening. If the knives are completely out of order, it is better to purchase a new set from the manufacturer. The attachment itself is a cutter or drum mounted in a bearing assembly. Actuation is carried out by a belt drive, and the rotation speed is regulated by the force of pressing the accelerator handle. The diameter of the pulley also affects the speed: the larger it is, the higher the speed. Studs for installing the nozzle are included in the kit.

Why does a chainsaw make noise?

There are a few different reasons why chainsaws are so loud. These 3 factors create the most noise:

• engine/motor;
• sawing;
• vibrations.

You've probably already guessed that the engine is the main culprit behind the noise. This is why gas chainsaws are so loud compared to others, as their engines produce the most noise on average.

The cutting process will also add to the noise produced by the chainsaw. A chainsaw with an old chain that is no longer sharp and is not properly lubricated can potentially result in higher noise levels.

Vibrations, although to a much lesser extent, will also increase the overall noise level. One of the reasons electric and cordless chainsaws are much quieter is that they will generate less vibration.

User manual

When working with the Friendship saw, you must follow the operating rules:

• Start-up and operation is prohibited with a damaged or removed air filter;
• the instrument is held with two hands;
• To protect the operator, special clothing and glasses are used;
• at the moment of starting, the saw chain should not touch the ground, stones or other objects;
• It is not allowed to saw wood without filling the tank with oil;
• It is strictly forbidden to refuel the saw with pure gasoline;
• when operating the saw for a long time, it is necessary to take breaks to cool the motor (every 40-45 minutes);
• The tightness of threaded connections is periodically checked;
• If parts of the saw are damaged, operation of the tool is suspended.

Before using the saw, you should read the instructions from the manufacturer. To make a fuel mixture, you need to prepare gasoline and special oil. Half the volume of prepared gasoline is poured into a clean container, then lubricating fluid is added and mixed thoroughly. Then the remaining gasoline is poured into the mixture, the solution is further mixed and filled into the tank. When running in the engine (after replacing the rings), it is recommended to introduce additional oil to ensure the running-in of the rubbing surfaces.

When felling wood, a cut is first made, located on the side where the trunk should fall. Then the trunk is sawed on the other side; There should be no unauthorized persons within a radius of 50 m from the tree being cut down. The operator moves from trunk to trunk with the saw running at idle speed (without chain rotation) or with the engine off. The operating instructions do not allow sawing of trunks tied into logs or stacked.

During operation, it is necessary to adjust the engine idle speed and adjust the carburetor to achieve maximum power. The equipment requires adjustment of the clutch, which overheats during prolonged operation and loses its original characteristics. Since the saw chain stretches during operation, it is necessary to adjust the tension of the element. A correctly tensioned chain moves along the bar by hand and has no sagging in the lower branch.

How to make the exhaust quieter with your own hands

Upgrading your machine will help make it as quiet as possible. Everyone knows that noise cannot be completely eliminated, but it can be reduced. To create a quiet muffler, different methods are used:

• install another muffler in place of the old one;
• I install an additional resonator;
• install a resonator equipped with an absorbing filler.

Each of the above methods has advantages and disadvantages. If you are upgrading your car's exhaust system yourself to reduce the exhaust sound, you need to have everything you need for the job. For such manipulations you need to have a set of car mechanic tools. You will also undoubtedly need:

• Welding machine. If a choice is possible, then use a semi-automatic or inverter;
• Angle grinder (angle grinder) with a set of discs;
• A workbench equipped with a vice.

Before starting work, you must choose one of the methods for upgrading the exhaust pipe. The first method is to install another factory-made resonator in the area between the first resonator and the muffler. You can also make it yourself.

The first option is the simplest, most popular and accessible. When choosing a method for constructing a low-noise muffler, it is necessary to take into account that the chosen method will lead to various financial expenses. If the owner of the car has the required amount of money, then it is best to purchase a resonator, remove a fragment of the pipe and weld the purchased device into the free space. The second method is undoubtedly much more interesting. The manufacturing technology of such a mechanism must be carefully studied before proceeding with its implementation.

Let's compare the muffler for a saw with the muffler for a lawn mower

The operating principles of these devices are similar to each other. They create an air cushion inside themselves, which absorbs and dampens some of the sound waves. The differences between them lie, first of all, in the size and overall characteristics. This is why you can’t take a brush cutter and install a muffler on a saw.

. There are other, less fundamental differences related to design features:

• The device for dampening acoustic waves for the Druzhba chainsaw has a slightly elongated oval shape, the hole for the exhaust gases is round;
• The silencing device for the Ural gasoline saw has a trapezoidal shape and consists of two parts connected to each other by welding. The mounting hole for exhaust gases is rectangular;
• The original muffler for the Husqvarna 272 XP chain saw has a rectangular shape. Its design consists of an outer box, an exhaust damper tube, a spark arrestor, a hole for mounting screws and a mounting bracket; The muffler for German chainsaws Stihl MS 290, MS 310 and MS 390 is shaped like a miniature canister. The exhaust outlet is rectangular. Supplied complete with mounting bracket;
• The original part for the Stihl MS 440 chain saw has a square shape. Mounting holes for screws are located along its edges. The rectangular exhaust pipe is connected from below using two bolts.

In the BenzoZip online store you can purchase other spare parts and consumables necessary for the repair and maintenance of chain saws. In particular, we sell a piston group for chainsaws.

Alternative electrical circuit for electronic ignition for chainsaws.

The easiest to assemble and seemingly intricate and complex circuit will be the circuit that represents the electronic ignition unit of the chainsaw.

This scheme appeared after frequent requests to us for help in repairing chainsaws that had lost the spark discharge on the spark plug produced by the standard electronic unit.

The main reason for the electronic ignition unit to be out of working order is a break in the high-voltage wire or a large gap on the spark plug. Additional negative factors are moisture, damp dust covering the block and, in fact, the use of spark plugs that do not meet the operating and electrical parameters.

We redesigned the standard units to install the most affordable domestic parts on them, which reduces the cost of repairing the unit.

How to clean a chainsaw filter

It may be necessary to clean the Husqvarna chainsaw filter after each use. How to make a muffler on a chainsaw I recently saw a photo of a champion chainsaw. The cleaning process itself, depending on how dirty the filter is, can be done in two ways:

• A mechanical cleaning method, which involves blowing the filter.
• For higher degrees of contamination, the filter is washed in soapy water.

Important! It is forbidden to wash the filter in aggressive solutions: gasoline, diesel fuel, acetone.

Build process

There are several directions for upgrading a chainsaw with your own hands. With the right approach, a homemade exhaust system will operate effectively without reducing the power of the unit.

The easiest way to get rid of the noise is to use a flexible plastic duct and a container of water. The hose is screwed to the exhaust pipe through heat-insulating gaskets, its other end is lowered into the water and rigidly fixed to the tank.

Gradually cooling and losing speed, the exhaust leaves the engine freely. Contact with air is neutralized by water. To make a similar muffler for a chainsaw, you will need at least 3 m of flexible pipes and a bucket with a capacity of 10-12 liters. This design is suitable for working on a flat, open place without moving around the area. Used for cutting firewood or timber in the courtyard of the house.

A drop in device power and loud sounds at low speeds can be caused by a clogged muffler. Passing through the narrowed hole, the exhaust gases emit a strong roar. In some cases, the instrument makes loud noises that resemble gunshots.

This problem can be solved in the following ways:

1. Disassemble the unit in accordance with the attached instructions. Remove the exhaust system, remove carbon deposits from it, wash off solid deposits with solvent or gasoline. Degrease the parts and put them in place. The elements do not need lubrication, since it burns when it comes into contact with exhaust gases.
2. Clean the exhaust system mechanically. It should first be dried with a hair dryer, since the sticky substance is difficult to clean off. Carbon deposits are removed using a brush with hard plastic bristles. It is not recommended to use steel fixtures, as they scratch the metal, which leads to accelerated wear of the product.

You can prevent rapid clogging of the muffler by preparing a fuel mixture of high-quality gasoline and oil, which must be mixed in the proportion specified by the manufacturer.

The work is carried out in the following sequence:

1. A pattern is made for bending pipes from tin. It is necessary to make two blanks. One should be equal to the exhaust hole. The second is machined with a cross-section 2-2.5 cm larger. For this purpose, it is better to use fine-grained hardwood.
2. The stainless steel sheet is cut into pieces of the required length and width. They are wrapped around the rollers. This is done with the help of muscular strength and a hammer. To simplify the process, one edge of the workpiece is rigidly attached to the rollers with nails or screws.
3. The edges of the bent pipes are aligned and welded together. On a wide workpiece, the seam is leveled and polished. This is necessary for the safety of the master and to give the product a presentable appearance. Without this, tuning a chainsaw will be incomplete.
4. Many holes with a diameter of 3 mm are drilled in a thin pipe. They can be done in any order with an interval of at least 5 mm.
5. Metal wool, basalt cord and aluminum wire are wound over the drilled workpiece. The fixation must be tight so that the filler is not blown out by gases under pressure.
6. An outer pipe is stretched over the resulting product. They are fastened using bolts or screws. The front facade is welded with a steel washer.
7. The finished muffler is attached to the exhaust pipe of the chainsaw. It is better to fix it with rivets.

It doesn’t take much time to make such a device and it’s inexpensive. But the product can last for several years; it only needs to be periodically cleaned to remove accumulated carbon deposits.

Good day, dear readers and subscribers of Andrey Noak’s Blog. Here, recently, my neighbor in the country was cutting down trees on his property and preparing firewood. Naturally I used a chainsaw. Although he purchased not a professional saw, but a household one, it made a lot of noise. While he was working, all the neighbors, including me, were tired of this noise. That’s when the idea came to me, to tell him how to make a muffler for a chainsaw with your own hands.

Required materials and tools

In standard cutting products, the exhaust system is made as short as possible. This decision is made to achieve the power required to quickly rotate the chain. In order not to degrade the performance characteristics of equipment and to make it quieter, a thoughtful and comprehensive approach is required.

Making a muffler for a chainsaw with your own hands requires the following tools:

• roulette;
• welding machine;
• metal scissors;
• Bulgarian;
• hammer;
• core;
• marker;
• riveter;
• file;
• electric drill;
• construction hair dryer;
• screwdrivers.

Depending on the specifics of the improvements being made, the following materials may be required:

• sheet stainless steel;
• rivets;
• bolts;
• screws;
• basalt fireproof cord;
• wire;
• solid wood for rollers.

To protect your hands, skin, eyesight and breathing, you should use the following means during work:

• respirator;
• thick clothes;
• assembly gloves;
• glasses;
• construction helmet.

The design of the instrument provides for partial absorption of noise by the body. If there are large gaps in it, they can be sealed with silicone-based mastic. The material will reduce vibration, rattling of plastic and metal.

Do it yourself

In order to save money and time spent searching for the right workshops, I advise you to make a muffler at home. It's not as difficult as it seems at first glance.

All you need is a regular 1mm stainless steel sheet, an iron tube with a smaller diameter than the muffler, stainless steel wool, basalt fiber and a little patience.

Sequence of work:

We take a sheet of steel and wrap it around the rollers, in the end we get a round tube, but you will definitely need an oval-shaped pipe. To do this, use welding to heat and then press down the tube, you should get an oval shape; If you have a ready-made pipe of a suitable diameter, then this is good, if not, then you need to make it using a welding machine. To do this, take a metal sheet, mark the required dimensions and cut it by welding. Then we make a pipe, the seam should be thin and without bumps; When you have a finished pipe, you need to make as many holes in it as possible, and you can make holes either chaotically or in a strict order, it doesn’t matter at all; Next, we take the stainless steel prepared in advance and begin to wrap the outside of the pipe

This is necessary to prevent the muffler casing from blowing out; Then we wrap basalt fiber over the stainless wool (this is the most suitable material) and so that it all does not slip, we fasten it with wire, which should be thin and at the same time strong; We insert the wrapped pipe into the future apparatus and rub it all down with sandpaper, paying special attention to the seams and joints so that they do not stick out too much; When you have done all this, the resulting unit must be attached to the chainsaw as tightly as possible so that it does not fly off at the right moment.

Such a homemade device, if done correctly, will serve for a long time and will significantly reduce engine noise; it works well on Druzhba chainsaws. Another advantage of a homemade muffler is that it will cost you a meager amount. It will only cost you time, but it's worth it.

You can also use this version of the muffler: install partitions in the pipe, which is located in the muffler, and thereby reduce the noise level of the engine. This is explained by the fact that the noise itself is a strong vibration of air, which comes out of the muffler at great speed.

In order to reduce operating noise, it is enough just to drill holes in the pipe and insert partitions into them at equal distances. There will be many divisions and the gas will gradually come out, while the pressure and noise will decrease. Accordingly, the speed of gas movement will decrease, which will lead to a decrease in noise.

If you want to make the gases leave the cylinders faster, thereby reducing the engine effort so that the saw’s performance increases, remember that the noise will be several times greater.

In order to achieve this, you need a direct-flow muffler, which can be made from a pipe according to the sketches of an old muffler, unscrewing and subsequently using all the bolts and nuts.

I advise you to choose a steel pipe, then the muffler will last longer. If there is no suitable steel pipe, then you need to make one using a steel sheet. Using a welding machine, you can make a tube of the desired diameter and size.

Everything is already provided by the factory, everything should work as one whole, and if you try to change anything yourself, including improving the muffler, without any drawings, then it is quite difficult and not everyone can succeed.

For chainsaws such as Shtil 180, it is better to buy a native muffler, which you can change yourself without any problems.

Therefore, if you have certain knowledge and good ingenuity, then you should try to make an additional muffler yourself, thereby saving money and perhaps you will be able to make a device that will actually make the chainsaw work much quieter and you will not have to constantly quarrel with neighbors or others you people.

What is a muffler?

This is a special unit that is designed to reduce the noise level from the operation of a car engine, chainsaw and other equipment of a similar nature. In other words, the muffler is able to reduce the noise that accompanies the operation of the engine. But how to make it yourself? To do this, you can use available materials. The tools you will need are a welding machine, a drill, drills of different sizes, sandpaper, thin wire, stainless wool and basalt fiber.

We reduce noise with our own hands

To do this, perform the following steps:

1. Take a sheet of stainless steel, 1 mm thick, and roll it on the rollers. As a result, you should get a round pipe, but then you need to bring it to an oval shape. If you have a ready-made pipe with parameters that match the parameters of your chainsaw, you can use it;
2. Weld the joint and press down a little to get an oval shape;
3. We make a pipe of smaller diameter than the muffler, and make many holes in it so that the pipe becomes perforated;
4. We wrap perforated pipes with stainless wool to prevent the muffler packing from being blown out;
5. All that remains is to wrap the basalt fiber over the stainless wool as firmly and reliably as possible. Use strong, thin-diameter wire for this;
6. We fill the inside of the future muffler with perforated pipes wrapped in stainless wool;
7. Carefully rub and then polish the seams using fine sandpaper;
8. We connect the resulting unit to the chainsaw as securely as possible.

A chainsaw is a very popular technique these days. It has found its application in many areas of human life. Therefore, manufacturers around the world are creating more and more models with high power and light weight. However, high-power models are quite noisy. To reduce the noise level, you can build a muffler yourself, as shown in the following video.

Why does a chainsaw make noise?

All chainsaws have only one significant drawback - noise during operation, which in some places (dachas, garden plots) bothers and irritates many people. If the noise from a running saw makes it difficult to concentrate, then another option is headphones that suppress the noise. But everyone around you won’t wear headphones while someone else is making noise.

A clogged or improperly repaired muffler is the reason why the engine constantly stalls or does not start at all.

It happens that a chainsaw works normally at low speeds, but as soon as you add gas, it immediately sneezes and stalls. The reason, as a rule, is that the exhaust cannot pass through the muffler clogged with smoke and is forced to move in the opposite direction. To do this, it is enough to remove it and clean it, if of course it is disassembled, if not, then you will have to dry it with hot air using a hairdryer.

The main reason for muffler contamination is an excess amount of oil, which is diluted with gasoline and, as a result, settles on its walls.

If you decide to clean a non-removable muffler yourself, keep in mind that you cannot do it dry using the same hair dryer, since hazardous substances are extremely harmful to health.

Although most chainsaw manufacturers try to muffle engine noise as much as possible, this does not lead to anything good and primarily affects the power of the device.

Professional chainsaws, for example Husqvarna, cannot work quietly at all, since the power and speed are very high, which leads to a lot of noise. Trying to muffle the roar of the engine on your own while maintaining high performance is extremely difficult. But there are people who use an ordinary bucket of water and a plastic tube, lower one end into the water, and screw the other end to the exhaust pipe. Such actions are effective; the sound of the engine becomes quieter.

I need a specialist who will make a muffler for calm conditions. I am engaged in the production of wooden houses and when 10-12 saws are working it is a disaster. There are residential buildings 100 meters away and I’m afraid that the residents will soon dislike me, to put it mildly. If anyone can make it, I'll buy it.

Install a sound-reflecting fence, you can even make a mobile version, but with two-stroke saws (if the saws are two-stroke, and I, for example, did not have to work with 4-stroke ones), it’s not very easy to clean up anything with the exhaust.

Chainsaws already have mufflers. It makes no sense to modify them, i.e. theoretically this can be done, but it is difficult to predict how the characteristics of the engine will change and whether it will work at all.

I also faced similar problems.

Probably only these options:

Well, in general, there doesn’t seem to be anything complicated. Purely theoretically: They took an ordinary tin can, made holes in it, wrapped it in glass wool and screwed it to the standard plug with self-tapping screws. But I think the sound will actually decrease by 10 decibels, and for it to be completely quiet, the muffler should be like a car. A sound-reflecting fence is a great idea. It might work.

Flange onto the cylinder, hose onto the flange and into a canister of water. It will be like on a boat motor. Mobility will indeed decrease...But.

hi, did someone repeat this?

I also wanted to throw in 10 kopecks, because... I worked in a car repair shop before, they made direct-flow mufflers with bass tips for street racers. For those interested: » >

I would choose electric saws so that I can use them wherever possible, and use gasoline when it is impossible to work electrically. Power saws probably don’t roll, because... We’ve already bought a bunch of chainsaws, but it’s too expensive to buy an electric one. The quietest but non-mobile option has already been mentioned - a hose into a bucket of water. This is how lumberjacks and poachers use chemicals. If the muffler is in the form of a barrel cube, then unscrew the 3 bolts (nuts) that stick out from it, take out the plug (or what’s inside? A cone?) and put a homemade flange of some kind on the 3 holes, to which a hose is connected to a bucket of water . The main thing here is to count: cut 10-12 of these flanges from roofing iron with metal scissors or make 10-12 noise-proof fences. By the way, stock up on hoses - rubber ones burn out quickly, you need something with metal. shell. And as for “the engine won’t work properly,” look at how the Americans have converted 2-stroke chainsaws on their model airplanes: just an exhaust pipe and that’s it!

How to reduce chainsaw noise

The operation of a chainsaw is accompanied by the exhaust of gases and loud noise. You can reduce noise using simple methods or using a homemade muffler, the design of which will be discussed below.

To reduce noise, you can place a small steel wool in the factory muffler of a chainsaw. The noise level will decrease, and with it the power of the gas-powered tool. For this reason, this method of reducing chainsaw noise is not suitable for anyone.

By the way, a faulty or dirty chainsaw muffler is also the reason why the noise level increases sharply.

In addition, due to a heavily dirty muffler, the chainsaw may stall all the time or even refuse to start.

In this case, it will be enough to remove the chainsaw muffler, disassemble it, and thoroughly clean the inside of carbon deposits. As a rule, in most cases, the reason for its strong formation is the disturbed proportions of gasoline and oil. In this case, more oil is added to gasoline than is necessary.

The second way to reduce noise is to install another muffler, if, of course, it takes its rightful place. You can even use a regular spray bottle with a built-in metal tube inside. In this case, the impact sound when operating the chainsaw will almost completely disappear.

The walk-behind tractor shoots into the muffler: what to do?

The owner of such useful and multifunctional equipment needs to know that interruptions in the operation of the muffler can occur due to:

• thin and low-quality metal;
• frequent potholes;
• excessive loads;
• difficult work;
• fastenings of an ill-conceived plan.

Important Design and operating principles of the MAZ clutch mechanism

Often the cause of popping noises in the muffler are gaps in the process of supplying sparks and spark plugs. To get rid of the problem, you need to unscrew the spark plug, combine its body and mass, turning the crankshaft using the existing starting handle.

At the same time, you should pay attention to whether a spark appears. If even after these manipulations the situation does not change, it is advisable to thoroughly clean the spark plug

DIY repair

When the above measures do not eliminate the problem, the reasons may be as follows. The electronic ignition unit has failed. All elements of this unit are sealed (filled with compound) and cannot be repaired. The entire unit needs to be replaced.

The cam (contact) ignition system of the Druzhba chainsaw is repairable. There are several reasons for its failure:

1. The textolite insulator of the moving contact of the breaker was pierced to ground. Replaces with a working one without any options.
2. The moving and fixed contacts of the breaker (cams) were burnt. Clean with a fine file or emery until the surfaces are smoothly adjacent to each other. They change when completely burned out.
3. The capacitor is designed to protect contacts from burnout. It rarely fails and does not directly affect the formation of a spark. When diagnosing, it is simply ignored.
4. Interturn short circuit, break in the secondary high-voltage turns of a coil with a thin wire.

Why does the spark plug on a chainsaw flood?

In most cases, the cause of a flooded spark plug is a breakdown or clogging of the carburetor. To disassemble, inspect and wash it, the fuel assembly will need to be removed.

To do this you need:

1. Unscrew the 3 metal screws and remove the protective plastic cover;
2. Carefully remove the upper foam part of the air filter. In this case, you need to inspect the filter element and make sure that there is no need to wash or replace it;
3. Remove the fuel hose, being careful not to tear or bend it;
4. Remove the drive rod;
5. Carefully disconnect the gas supply pipe and the end of the standard cable.

Which to choose

The direct-flow muffling system can be attached directly to the factory saw muffling element. The noise is noticeably reduced: sound damping ensures a narrowing into the funnel of the internal cross-section. However, being large, the structure can prevent free operation.

A threaded muffler for a chainsaw is also attached to the original one. It is small, has an inlet tube with holes that are separated by a helical partition. The exhaust gases entering the pipe exit through holes whose diameters are not the same. This ensures fragmentation of the exhaust force and dampening of sound.

Industrially manufactured silencers meet all safety requirements.

In two-stroke engines, and most chainsaws are equipped with such, the silencer is part of the engine, since a certain portion of the working mixture, after being dumped, again enters the cylinder. Therefore, it must be taken into account that any intervention into the mechanism in order to make operation quieter creates the risk of overheating the system or reducing its power.

Direct flow muffler

Such mufflers are often installed on sports cars. So, making such a muffler with your own hands and installing it on a VAZ would be a little inappropriate.

With this design there is no sound absorber. Exhaust gases move in a vicious circle. Due to some specific features of such a system, gases leave the engine faster, and the efficiency of the engine increases. At the end of the work, you will need to adjust the entire power system.

To make such an exhaust system with our own hands, we need to take: a stainless steel sheet, pipes, welding, mineral wool, a heat-resistant insulator, and a grinding machine.

After this, you need to weld another pipe onto the pipe. Its diameter should be about 20 centimeters and its length about a meter. We insert this mechanism into the body of your old muffler and weld the body.

Next, we use cotton wool to cover the top of the muffler. Cover the top, slightly overlapping, with a stainless steel sheet. In this simple way we made noise insulation for our muffler. Now you can install your muffler.

Fuel system malfunctions

The main sign of a malfunction in the Shtilev fuel system is that no fuel is supplied to the engine cylinder. Most likely, the problem is in the fuel hose or the condition of the membrane. If they are intact and there is no blockage downwards, the reasons should be sought in a clogged breather or special filter.

If the fuel is supplied by spitting, the stream is weak, most likely the breather is clogged. It must be carefully cleaned with a sharp nail or needle.

In rare cases, fuel does not enter the cylinder correctly due to clogged carburetor passages. It also needs to be cleaned mechanically with a thin screwdriver or wood chips.

How to make a quiet muffler on a car - tuning the silence

Only a small part of car enthusiasts would like to have a loud sports exhaust on their car. The vast majority of drivers, on the contrary, are puzzled by the question of how to make a quiet muffler.

Driving can be comfortable only if as little extraneous sounds as possible enter the cabin. The muffler creates its own background noise, which can be significantly reduced.

The effect of this cannot be ignored.

Basic ways to make a muffler quieter

Before you begin upgrading your exhaust system, you should understand the nature of the increased exhaust sound.

With each working stroke of the piston, a micro-explosion occurs in the combustion chamber of the engine cylinder, which is accompanied by a significant sharp expansion of gases.

Naturally, a kind of blast wave, after it has done its job and moved the piston down, rushes through the exhaust system with the opening of the exhaust valve.

Thus, the nature of exhaust system noise is twofold:

• sound from expansion of gases;
• noise from vibration of exhaust system elements.

As you know, the main way to combat noise is to increase the weight of the elements. The thicker the metal, the less vibration and, accordingly, noise. That is why the exhaust manifold, which is the first to absorb hot gases from the cylinder head, is made so massive.

Many car enthusiasts who had the opportunity to compare the weight of the exhaust pipe of a domestic car and a foreign one noted that the exhaust system parts of foreign cars are much heavier. This is why “our” cars are less comfortable in sound and noise comparisons.

Special elements are designed to reduce the speed of gas movement in the exhaust pipe: resonators and mufflers. First in line is the resonator.

In the muffler labyrinth system, the exhaust gases finally lose their energy and are dissipated. A real quiet muffler on a foreign car is quite heavy and has several separate housings.

Making a quiet muffler with your own hands

When starting to modernize the exhaust system in order to reduce exhaust sound, you should be prepared technically and financially. For work you will need a full set of car mechanic tools. In addition, you will definitely need:

• welding machine (preferably semi-automatic or inverter);
• angle grinder with a set of discs;
• a workbench equipped with a vice.

One of the most affordable ways to get a quiet muffler in the average garage is to include an additional resonator in the existing exhaust system.

https://youtube.com/watch?v=-fSsYErK6PY

There are also two options for upgrading the exhaust system: installing an additional factory-made resonator in the area between the main resonator and the muffler, or making the device yourself.

When considering how to make a muffler quieter, you should keep in mind that either option may entail different costs.

If the car enthusiast is not limited by budget, then you can safely buy a new resonator, cut out part of the pipe and weld it into the free space.

The second method turns out to be more exciting and should be described in more detail.

The manufacturing technology of an additional resonator consists of the following stages:

• manufacturing a body (barrel) from a piece of thin-walled steel pipe or sheet steel in the form of two halves;
• making holes in a section of the exhaust system pipe corresponding to the length of the body behind the main resonator;
• connecting the body halves on a pipe with holes and scalding;
• laying basalt mineral wool into the cavity of the new body;
• welding of the end parts of the resonator.

Finally, the welds should be processed, the new resonator should be cleaned and degreased, and if possible, painted with heat-resistant paint.

Additional problems of a quiet car

Once the question of how to make a quiet muffler has been resolved, some problem areas become apparent. First of all, it should be remembered that any of the methods for producing a “quiet” exhaust system will certainly lead to an increase in the weight of the structure.

This, in turn, obliges the car owner to take additional measures to strengthen the brackets and rubber shock absorbers.

Another point to consider is the change in the balance of air entering the engine and exhaust gases.

After upgrading the exhaust system, it is imperative to test the operation of the engine in different modes and make additional adjustments to the fuel supply and air filtration system.

Chainsaw Friendship 4

Operation of the Friendship chainsaw: 1. Non-specialized PART.
First of all, go to fell rotten and burnt trees, Figure 1—View of the saw from the muffler side Adjusting the carburetor of a friendship chainsaw. The carburetor installed on saws consists of a body, the inner part of which is made in the form of an air nozzle (Venturi nozzle). Friendship chainsaw repair is best left to specialists. There is still no clear opinion about the Druzhba chainsaw. Many consider this unit to be a reliable “workhorse”, while others are offended by the clumsiness and capriciousness of the unit. The Druzhba chainsaw is still being produced, and is supplied not only to the domestic market, but also abroad. Due to the mass production, this device can be found in virtually any rural farmstead.

The question of reliability and convenience remains open, despite the fact that every third unit has served the owner for at least 20 years. Chainsaw Friendship 4 - maintenance and repair Adjusting the carburetor of the chainsaw Friendship 4. Some miniatures are cut off. When viewed in full, the photos will be displayed without loss. Click on the picture to see it in full size.

The weak point of the model is the crankshaft main bearing. Due to malfunctions, the ignition is disrupted and the operation of the equipment becomes unpredictable. In this case, it is impossible to start the saw, and from time to time it is impossible to turn it off.

The forced stop button was installed on the domestic model quite recently, but many craftsmen installed it on their own before. The Druzhba 4 chainsaw, which owners have to repair with their own hands, has a huge list of failures under intense load. These include piston jamming, gearbox damage, connecting rod breakage and loss of spark.

The Friendship chainsaw, which is not a cheap pleasure to repair, requires constant tuning and adjustment. Frequent problems with the carburetor are solved by bending the gasoline valve inward. This limits the amount of fuel entering the engine. Another reason for the chainsaw to not work is the lack of tightness between the cylinder and the carburetor. In this case, use a special sealant or wrap the transition coupling with a narrow tin strip.

For high-quality operation of the chainsaw, all connections must be sealed, including carburetor membranes and gasoline pipes. Many owners of these devices claim that the equipment is unpretentious, it can be cleaned in the field, then it is again ready for battle. The easiest thing to do is adjust the carburetor of the Druzhba chainsaw, since instructions for its maintenance are easy to find. Repair in any situation Anna Lazar. Chainsaw repair “Friendship.
