Muffler VAZ 2110 8 valves injector diagram

Design features

The vehicle's exhaust gas removal system allows not only to remove fuel combustion products, but also to increase the efficiency of the power unit, as well as significantly reduce background noise.
To do this, the system uses a component such as a muffler, which is capable of suppressing the noise created by exhaust gases and significantly reducing their toxicity level. All these indicators depend on how the muffler is designed. Regardless of whether the muffler is manufactured in a factory or assembled by hand, its design must contain the following mandatory elements:

• The exhaust manifold articulates directly with the car's engine through a exhaust pipe, which can be equipped with a vibration compensator.
• Exhaust gases from the exhaust pipe enter the cavity of the catalyst, in which the remaining fuel burns out, and the saturation of carbon dioxide decreases.
• From the catalyst, gas flows flow into the resonator chamber, where vibrations are damped and the effect of their pulsation is balanced.
• Then the volume of exhaust gas flows passes through the chambers of the rear muffler, which is designed to reduce noise.

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2.

Which VAZ muffler is better, original or cooperative?

Original VAZ mufflers of the tenth family produced by AvtoVAZAgregat. Compared to cooperative mufflers, they have significantly more weight (thicker walls), and therefore a longer service life (3-5 times). In addition, there is a special cotton wool inside the factory muffler, which is not always available in the “cooperative”. The only thing that makes you choose a cooperative is the price.

Approximate price of VAZ mufflers :

• Original - 2300 rub.
• Cooperative -1000 rub.

Is the muffler made of stainless steel or a regular alloy? Stainless steel is a heat-resistant metal, so the service life of such a muffler is longer. But they are quite rare on sale (more often they are ordered), and the cost of stainless steel is higher than mufflers made of aluminum alloys.

How to determine whether a muffler is faulty

All original mechanisms on the VAZ 2110–2112 are adjusted at the factory to ensure a minimum noise level while driving. At the same time, engineers take into account not only the design of the engine itself, but also the car body. Therefore, after tuning the car, the noise level of the muffler increases sharply.

The main malfunctions of the muffler are those factors that interfere with its correct operation:

• burnouts;
• formation of holes in the body;
• violation of tightness.

The use of such an element is unsafe for the driver

The most common problem with silencers on VAZ 2110–2112 can be considered the occurrence of knocking noises while driving. Even new and original products can cling to the bottom of the car and make loud noises:

Not long ago I received my license and became the proud owner of a VAZ 2112, I am satisfied with the car in all respects. A strange problem appeared: the muffler began to knock on the bumper or on the bottom of the car, it’s difficult to say for sure. I went to the service center and they looked at it and they really said the muffler was a little crooked, so they started bending it as a result? It was bent, drove about 20 km and the knocking appeared again, the interesting thing is that it doesn’t knock all the time, but at some moments, maybe when driving or while standing at a traffic light.

Problems with the operation of the device on the VAZ 2110–2112 can be determined visually. To do this, it is recommended to drive the car into a viewing hole or lift the rear of the body on a jack:

1. Inspect the entire exhaust system pipe. The presence of holes can be noticed immediately. In addition, rust spots will indicate that there is clearly damage inside the muffler housing.
2. Rock the mechanism with your hand - if it sways too much, then it’s time to change the fixation rubber bands and the reinforced gasket between the parts of the muffler.
3. After leaving the inspection hole, start the engine and sharply press the gas pedal several times - black exhaust smoke indicates severe burnout of the product.

Why do you need a gasket?

The gasket is an essential element between the main muffler and the resonator. Since all parts of the exhaust system become very hot, the gasket is made of heat-resistant materials.

If, when replacing a resonator or muffler, a gasket is not inserted between them, then the joint will not be as tight as possible. In addition, when driving on uneven roads, the two elements will rub against each other and quickly fail.

There is no need to worry about the procedure for replacing the gasket: it has a convenient shape and is placed on the element pipe with one movement of the hand:

1. Attach the gasket to the resonator flange.
2. Tighten 4 bolts.
3. Make sure the insert is kept level.
4. Tighten the bolts until they stop, without overtightening them.

Replacing rubber bands

The VAZ 2110–2112 muffler is attached to the bottom of the car with special rubber hangers. The elastic bands have minimal elasticity, so they can ensure reliable fixation of the mechanism. Usually two rubber bands are used - one is placed at the exhaust port, the other at the compartment with the resonator.

To change the suspension rubber bands, you need to place some kind of support (boards or bricks) under the device to fix its position at the maximum height. After this, the old rubber bands are removed. If necessary, the hooks on the bottom, on which new rubber bands are put on, can be cleaned of dirt and carbon deposits. After which the muffler is easily attached with hooks to the new rubber hangers. The suspensions are removed one by one from the front of the car to the rear.

The special rubber composition allows you to keep the muffler in the desired position for many years

What to do if the muffler is knocking

Knocking is one of the most common problems with silencers on the VAZ of the tenth family. Mufflers can knock only in two cases: when, while driving, they touch the body of the gas tank or swing so that they hit the body.

The knocking can be eliminated by simply replacing the rubber suspensions: during operation they can stretch, so the muffler no longer has a reliable fixation to the bottom. In addition, the “silencer” can often knock because it was installed incorrectly during installation: for example, the flange is not fully tightened or the bolts do not match the length of the bracket. Therefore, the replacement procedure must take into account all the nuances of the correct installation of exhaust system elements.

What are mufflers for Lada made of: we conduct a laboratory examination of 12 samples

The main task of a car muffler is to reduce noise and reduce the temperature of engine exhaust gases. In this case, the parameters of the muffler depend both on its design and on the quality of the materials from which it is made. It is impossible for an ordinary consumer to determine the composition of the metal and compliance with the declared parameters in a store, and therefore the magazine “Engine” decided to conduct a laboratory analysis and find out what mufflers are made of for front-wheel drive VAZ models of the Samara .

Classifying mufflers according to design features, the following main types can be distinguished: active (dissipative), combined, direct-flow, reactive (resonant) and labyrinth.

The operating principle of an active muffler is to convert sound energy into heat as sound waves pass through a sound-absorbing material - basalt fiber. Such mufflers have a very simple design; they dampen high-frequency noise well, but do not cope well with low frequencies.

The reactive muffler is designed in the form of several (from two to four) resonating chambers of various lengths, through which one or more perforated pipes pass. The operating principle of this type of muffler is based on the addition of sound waves until they destroy each other. But such mufflers only dampen certain frequencies of noise.

A combined muffler consists of resonant and dissipative chambers, while a direct-flow muffler consists of a single pipe that directs the flow of exhaust gases through all chambers. The advantage of the latter is low back pressure.

A labyrinth muffler consists of separate inlet and outlet pipes and several chambers in which the flow of gases moves randomly, which makes it possible to effectively reduce the sound level. The downside of such mufflers is that more resistance is created, therefore, engine thrust is reduced. But for passenger cars, where low noise levels and passenger comfort are a priority, this type of muffler is best suited.

How to replace the main muffler on a VAZ 2110–2112 with your own hands

Before starting work, you need to make sure that you have all the necessary tools and auxiliary materials at hand:

• set of wrenches;
• a screwdriver with a flat and thin blade;
• WD-40 liquid;
• Bulgarian;
• new bolts;
• soft fabric.

The procedure for dismantling work

To remove the muffler, you will again have to drive the car into the inspection hole. When parking the car, you need to make sure that the wheels are securely locked (it is better to engage first gear and raise the handbrake).

Removal is carried out according to the following scheme:

1. The front part of the mechanism is secured with bolts. If you can’t unscrew them right away, then you need to spray WD-40 on the fasteners and wait 10 minutes until the grease is absorbed. In the event that the bolts are so badly rusted that they cannot be unscrewed, you will have to connect the grinder to the work and cut off the fasteners.
2. After this, the graphite sealing ring is removed.
3. Next, you can remove the rear part of the muffler from the suspension rubber bands.

The device is removed from under the car.

If unscrewing is difficult, it is recommended to file the bolts

Installation procedure for a new muffler

After which it is recommended to clean the muffler mounting points on the underbody. On old cars, they become so covered with dirt or rust that it is impossible to secure the new plug well without first cleaning it.

After this you can start installation:

1. First, hang new rubber bands on the hooks and secure the back of the device to them.
2. Hang the new element and secure a new graphite gasket at the junction of the two pipes.
3. Then hang the front part of the muffler on the bracket and secure it with new bolts.
4. Check the reliability of all fastenings by loosening the mechanism with your hands. If the product only slightly vibrates, then we can say that the installation was done with high quality.

The muffler is easily fixed with rubber bands

In general, replacing the main “glushak” with a VAZ 2110–2112 does not present any particular difficulties. It can take a lot of time to unscrew or saw off old bolted connections if the mechanism has not been changed for a long time. The remaining stages of work are accessible even to a beginner.

Video: how to replace the “glushak” yourself

How to change an additional muffler

The additional muffler on the VAZ of the tenth family is not attached to the bottom of the car. It is connected to the inlet pipe using ties (clamps). Accordingly, to replace the additional muffler, you need to remove these clamps:

1. First, the main mechanism is dismantled.
2. Then the clamp nut is lowered.
3. Use a screwdriver to open the clamp and move it down the tube.
4. The additional muffler swings and is removed from the pipe.

"Car muffler"

Price: 760 rubles

The cheapest of the samples we purchased, which affects the quality of its manufacture. The ramjet type muffler is painted along with pieces of tape. The paint itself crumbles when touched. Due to the reduced length of the can, the manufacturer had to lengthen the hooks to secure the muffler. Compared to other manufacturers, a pipe of the smallest cross-section is used; bends further narrow the pipe to 32 mm in outer diameter. Rust has already appeared in places where the paint is damaged. The inside of the muffler uses a perforated twisted sheet with welding points. The slightly extruded stamping of the manufacturer AG is barely visible on the muffler body. A label with a list of manufactured products is taped to the jar. Not a word about the guarantee.

"Izhora muffler" 135884

Price: 994 rubles

By design, the muffler is a simple three-chamber reactive type muffler. Accordion folds formed in the places where the pipes were bent. The soft side hook fastening is welded to the wall of the can on only one side - there is a high risk that it will be deformed during transportation. There are some stuck welding splashes on the surface of the can.

"Ekris" 1201005

Price: 1090 rubles

This muffler is heavier than the second model with index -01 due to the increased thickness of the pipes. Unfortunately, no other information about the differences between the two models could be found even on the manufacturer’s website. The packaging indicates that there are two types of mufflers: reinforced and aluminized. But it was also not possible to find any indications of which muffler model each type belongs to. There are no complaints about the appearance of the product: the bends of the pipes are smooth, the welding is done carefully. Minor comments may arise regarding the side hook-fastening - it is attached to the can only on one side and can easily bend during transportation. No warranty information available.

Replacing pants

The exhaust pipe, also called pants (due to its appearance), is attached to the manifold using studs and nuts. Its fixation with the neutralizer is carried out by a spring-loaded connection.

1. Remove the exhaust pipe, paying special attention to its attachment to the manifold. Studs are used here, not bolts. They are screwed into the manifold, and connecting nuts are screwed onto them.
2. If the pin is damaged, it will be extremely difficult to replace it. Therefore, it is important to try to keep the old one intact and safe.
3. Treat the nuts with WD40, a product we all know. This will allow you to avoid using excessive force and keep the studs intact. If that doesn't work, the studs are drilled out. The process is complex, lengthy, and requires experience and skill.
4. There is a gasket between the manifold and the pants that needs to be replaced. Also install a new converter o-ring.
5. Now firmly press the exhaust pipe using the nuts. To do this you will need to compress the gasket.
6. Then tighten the bolts of the spring-loaded connection with the neutralizer of your VAZ 2110.

As you noticed, there is nothing complicated in this work. Each element is quite easily dismantled and a new one is installed in its place. Just be careful, act carefully and consistently. Plus, of course, do not forget about the importance of the quality of new parts. Buy only good spare parts that will ensure long-term and efficient service of the exhaust system on your VAZ 2110.

Transmaster AL

Price: 1229 rubles

This is an improvement on the previous version, made of aluminized steel, as indicated by the letters AL in the name, and with an additional double-sided coating. There are no complaints about the appearance: it is made carefully, the mounting brackets are reinforced with additional welded jumpers. Upon opening, it was discovered that the perforated tube inside the muffler already had traces of rust, which indicates that it was made from ordinary steel.

The muffler can is wrapped in a branded cardboard packaging with information about a 2-year warranty. This is the only combined type muffler presented, one of the chambers of which contains basalt sound-absorbing fiber.

Principle of operation

Before you begin repairing a car muffler or assembling it yourself, you need to understand the basic principles of its operation. If you look at the device in section, you can see many metal or ceramic partitions, heat-resistant wool, and the presence of perforated pipes. The presence of these elements in the muffler design slows down the speed of gas flows. When doing DIY repairs, it is important to replace worn-out elements with high-quality analogues.

In turn, their reduction allows you to smooth out the operation of the motor, taking into account each stroke.

There are no standards for the production of the exhaust system and its individual elements, so mufflers from different car manufacturers can differ significantly from each other.

If you decide to upgrade individual elements of the exhaust gas removal system with your own hands, then you need to take into account some nuances:

• powerful car engines must have a resonator of sufficiently large volume, which will provide the necessary level of exhaust smoothing;
• the number of partitions inside the chambers that smooth out the unevenness of the volume of discharged flows.

"Ekris" 1201005-01

Price: 1267 rubles

This is an improved and more expensive version of the Ekris model 1201005. The muffler is a labyrinth reactive type, all internal pipes are all-welded with a wall thickness of 1.5 mm, but are made of ordinary steel, as evidenced by the massive appearance of rust inside the muffler. The muffler completely replicates all the advantages and disadvantages of its “brother” described above.

"AvtoVAZagregat"

Price: 2004 rubles

The original and most expensive muffler for VAZ cars has the most unpresentable appearance. Numerous splashes and soot from welding, a very soft side fastening, welded with only one edge to the can, bends at the touch of a finger. Muffler of labyrinth reactive type. The inner tubes, which form a labyrinth for exhaust gases, have large areas covered with rust. No documents are supplied with the muffler, so we were unable to find out anything about the warranty.

Car muffler diagrams

A cross-section of a car muffler allows you to see exactly how the sound reduction function is implemented in each specific muffler. In direct-flow mufflers, for example, the method of changing the direction of gas movement is never used, and a standard muffler uses turns from 90 to 360 degrees. The change in the amplitude of sound wave oscillations is realized by perforating the internal pipes. It is these internal pipes, their diameter, diameter and frequency of holes that can drown out noise in almost the entire frequency spectrum.

But only the integrated use of these methods can guarantee high efficiency of the entire exhaust system as a whole. Therefore, modern cars use from one to six different mufflers. The main ones are the resonator and the main muffler.

Trial

First, the geometric dimensions and thickness of the metal used were checked, and the weight of each muffler was measured.

Then a strip of metal was cut from each can, which was submitted for metallographic examination to the Volna Plant NPO to determine the content of alloying elements (in particular, aluminum), which improve the properties of the manufacturing metal.

Aluminum is used as a steel deoxidizer, and its introduction during the smelting process makes it possible to bind harmful impurities such as oxygen and nitrogen, which reduce the mechanical properties of steel.

As the results of spectral analysis showed, all test samples contained aluminum, but in the Transmaster and Transmaster AL, SDV G014 and Izhora Muffler 136018 mufflers, its amount was negligible and had virtually no effect on the properties of steel. The last two specimens, in addition, had the largest amount of harmful impurities in the form of phosphorus and sulfur.

But the AvtoVAZagregat, AvtoMuffler, Izhora Muffler 135884 and SVD GAL012 mufflers, on the contrary, additionally contained titanium, niobium and vanadium, which indicates the use of higher quality steel.

However, the durability of the muffler depends not only on the quality of the metal, but also on its thickness, as well as a good design that does not create excessive resistance. The last two parameters, alas, left out a product with insufficient metal thickness (0.75 mm) and an exhaust pipe diameter (38 mm), which will also be narrowed to 32 mm, which will inevitably lead to an increase in resistance.

Manufacturing quality is the most obvious drawback of almost all of the suppressors tested. Rough welds, rust, crooked bends and fastenings, scuffs and dents. It feels like silencers in Russia are made in concentration camps from improvised materials.

Main components, operation and repair of the VAZ 2110 exhaust system

Any VAZ 2110 car is equipped with an exhaust gas exhaust system; without it, the vehicle cannot be operated.
The output device is a complex assembly consisting of many interacting parts. It is designed for safe, efficient removal of waste gas products, cooling them and eliminating noise. The exhaust design on all domestic cars is very similar, but each model has its own nuances.
