Each vehicle system, regardless of its application, is of great importance for the operability of the car. The exhaust system, despite the apparent secondaryness compared to the engine, has its impact on the efficiency of the fuel combustion system. Any specialists will say that the passability of the exhaust gases is the key to the "health" of the automotive motor. And, on the contrary, any obstacles on the way of products that are obtained when combustion of fuel in the engine cylinders are capable of significantly reduce the power of the car and even put its work. As a result of all the above, the knowledge of all the features of the exhaust system is an important component of the impeccable operation of the vehicle.

Device of the exhaust system 2114

The exhaust system of VAZ 2114 consists of different functional elements. Folding out in a single chain, it is balanced supports the operation of the motor in the optimal modes, controlling, while the noise level published by the power unit, the amount of harmful emissions, which are formed during the combustion process of the combustible mixture, and with the correct setting it allows you to efficiently apply the motor torque. On the VAZ 2114 the exhaust system consists of the following parts:

1. Graduation manifold. Fastened to the head of the cylinder block through the gasket and the first takes extremely high dynamic and thermal loads. The stock final manifold is made of thick metal to improve the temperature balance and maximize heat at the initial level.
2. Catalyst. Forced measures. A device that rigidly controls the amount of CO2 emissions to the environment. If the allowable emission rate is exceeded, the catalyst submits a message to the ECU, which, in turn, adjusts the composition of the mixture to achieve an optimal level of harmful emissions.
   
3. Silencer receiving pipe. Takes exhaust gases, after which it transfers their resonator.
   
4. Resonator. Metal tank equipped with oscillation damping system. Through several "acoustic mirrors" built into the housing, reduces the level of noise that arise with a strong exhaust.
   
5. Muffler. As well as the resonator, enhances the noise absorption of the exhaust system 2114. The muffler is located at the end of the graduation path.
   
6. Corrugations. With the help of its elastic structure, suppresses vibration, which is transmitted from the engine to the exhaust system.
   

muffler VAZ 2114.

The spent gases that leave the motor cylinders are high pressure. In the process of their movement along the graduation system, sound waves are formed, which apply to faster gases. The silencer converts the energy of sound waves into thermal energy, which makes it possible to achieve a reduction in noise level to a specified value. However, using the silencer in the release system, a backward is formed, leading to a certain reduction in the power of the power unit.

A number of noise reduction technologies are applied in the muffler:

1. Absorption of sound waves.
2. Interference sound waves.
3. Change flow direction.
4. The narrowing (extension) of the flow.

Modern car silencers are usually divided into three types - from aluminated steel, stainless steel and sports (straight-flow). Silencers on VAZ made from very durable stainless steel are one of the most popular types.

Such a greater prevalence among car owners, they obtained as a result of the simplicity of the material from which silencers are produced, and, therefore, the relative cheapness of the device itself. This type of silencers is actually universal, since it comes to many other automotive stamps. And everywhere, on which car, stainless steel silencers would not stand, they effectively and reliably perform their functions.

As for adaptations from aluminated steel, they cost a little more expensive. However, most often, it is more profitable to install them than cheaper analogues, since the warranty period of their operation is greater than seven, and even ten years. But as a result of its high cost, these devices are manufactured, as a rule, according to individual orders.

Directional (sports) silencers are mainly used in technical refinement of the vehicle to give it additional speed characteristics. Such devices are also made of stainless steel and apply on vehicles for racing (sports) purposes.

stinger VAZ 2114.

Among the owners of VAZ cars, Stinger is known as the manufacturer of the elements of the exhaust system tuning. The company began its robot 12 years ago from the manufacture of forward-flow for classic cars, today, under its brand, Stinger produces resonators, silencers, exhaust manifolds and related spare parts for VAZ and some foreign cars, in particular Kia, Daewoo, Gelly, Chevrolet and others .

The main advantage of Stinger is durability. We all know that the usual details for the exhaust system of car VAZ are not made of the highest quality materials, and their service life, as a rule, does not exceed four years.

Stinger is made from high-quality stainless steel, as well as paint powder paint. It is worth noting that with due care, it is capable of listening in two, or even three times longer than usual.

Elements of the exhaust system Stinger are created from stainless steel (08 ps). A non-combustible wool of foreign production is applied as a filler. A special barrier with a stainless grid prevents the blowing of the filler. The complete replacement of the exhaust system 2114 is able to add a car a few horsepower and significantly improve the dynamics, which will give the opportunity to leave behind many modern cars.

VAZ 2114 owners can choose between several variations of silencers - the FSA series, Stinger Sport Series or Mute Series. In addition, various additional details are provided, such as connecting clamp, rubber rings and decorative nozzles.

resonator VAZ 2114.

The resonator is an element of the exhaust system that quench the sound waves of exhaust gases that are pulled from the combustion chamber. Design, shape and size of the resonator directly affect the volume of the operation of the power unit. When breakdown in this element, there is a violation of the entire exhaust system. The vehicle becomes noisy, and the unpleasant smell of exhaust gases penetrates into the cabin.

The silencer resonator directly affects the power of the motor. The faster he manages to remove burnt gas from the power unit, the faster the motor burns fuel, and, therefore, the more power. However, unfortunately, the silencer resonator on the VAZ 2114, as well as on any other brands of cars, is constantly exposed to high temperatures, resulting in a quickly wearing.

Faults of the exhaust system

At the level of efficiency of the exhaust system as a whole, as well as its individual details, such unfavorable technological factors have their influence:

1. Development of external and internal corrosion.
2. Squares and scratches that are applied by small solid particles of the roadway.
3. Frequent pollution.
4. Frequent blows, as well as mechanical damage to the muffler.
5. Permanent vibration when working the power unit.
6. Sharp frequent oscillations of temperature modes - from cooling to rapid heating.

All considered factors in one of the other degree affect the performance and disadvantage of the exhaust assembly. If the integrity is violated, the gas flow immediately rushes into the resulting fistula or spill, which expands the emergency with its pressure and speed.

And then the breakdown makes itself felt - the exhaust gases go out in the wrong point, the system begins to clap loudly and "growl", knocks the muffler. Exploited the car in such conditions becomes actually impossible.

Keep in mind that in addition to sharp and loud cotton, the defects of the exhaust system 2114 are also able to influence the performance of the most power unit. Therefore, it sometimes has to repair individual elements of the system, which will allow for a while do without replacing the entire node as a whole.

The diagnosis of breakdown, preceding rehabilitation operations, facilitates the fact that the appearance of defects is accompanied, as a rule, an unpleasant strong roar and grinding under a car bottom. The car owner remains carefully examining the entire chain and diagnose the nature and place of malfunction. Most often, the malfunction occurs in such components:

1. Lambda probe. It is an electronic sensor that analyzes the composition of the outdated gases to ensure optimal combustion of the automotive fuel. Often, after one hundred thousand kilometers of the car, metal analyzers, which are part of the sensor, are able to lose their work properties. In this case, which spent its oxygen sensor, as a rule, is not repaired - it is simply changed to a new one.
2. Corrugation. The elastic hose of this element, taking on the vibration of the motor, with time stretches from such mechanical oscillations, which negatively affects the mitigation of the shaking. When breakdown, the old corrugation should be replaced with a new one.
   
3. Resonator. This element of the exhaust system 2114 under the influence of high combustion temperatures of flammable is able to systematically be lit. Often this is the result of the use of a low-quality fine stainless steel product. The best way to solve the problem is to replace the burned item to a new one. But it is possible to take temporary measures - to brew a place of reflog using a special electrode.
4. Connecting gaskets. The symptom of their breakdown is the occurrence of a strong vibration in the exhaust system in the exhaust engine. To eliminate loud rattling, it is often enough to simply replace the connecting gaskets.

Repair exhaust

The entire exhaust system is a complex of welded metal elements, for the repair of which the welding works will be required. The main misfortune of the muffler is the formation of through holes in the nozzles and the case.

There is a variant of temporary repair of damage using a special heat-resistant bandage with epoxy or cold welding. However, the service life of such Latan is small.

Repair work begins with the removal of the portion of the exhaust system, in which the "platoon" originated. Characteristic places are a resonator or silencer. Regardless of the reason for the formation of a fistula, it is treated with the same method - overlapping the lat.

For repair, the sheet metal segments should be prepared in advance. First, we determine the amount of damage. Places where there is already corrosion, it is necessary to remove completely, cutting out their corner grinding.

It is useful to treat the inner surfaces with a special anti-corrosion composition. Then cut out a fragment of a sheet metal that could close the missing plot, however, with some reserve - 1-1.5 centimeters. Next, it should be cleaned the place of welding and welcome the latch. It is advisable to use a welding semi-automatic, which is used for body welding. It is important that the welding seam is smooth and solid. In the same way eliminate the fault sites and slopes on the nozzles.

silencer repair

We change the sealing gaskets. In different models of cars, the number of sealing parts in the seal places is somewhat different. To replace the gasket in the silencer, it is necessary to dismantle the entire exhaust system or its small site. Despite the slight amount of fasteners, dismantling the muffler is able to drag on the clock. Before starting work, process fasteners with a special fluid, such as WD-40.

The process of replacing the gasket is not much difficult. You should remove the old sealing material and clean the junction location. The adjacent planes of the two elements of the muffler must touch with each other tightly. If there are small shells on metal flanges, use heat-resistant sealant.

We repair the muffler pipe. In the exhaust system of the car there are many pipes. They are straight and curved. As a rule, the exercise occur in the bending places, which is happening for several reasons:

1. Exhaust gases strongly affect the curved part.
2. When bending, the wall of the pipe is thinned.

To eliminate a large opening or cracks, use the welding machine. Sometimes it is possible to avoid dismantling the muffler, if there is an opportunity to get to the place of welding from the bottom of the car. A steel patch is welded on the problem area or welding seam is applied.

Not rarely depressurizing the system occurs in the junction of the pipe with a tank or a resonator. In this case, the damaged area will have to disassemble from the car and try to restore it. To do this, you will need: a piece of sheet metal, a metal rod or a segment of a wire, welding semi-automatic.

First, we remove from the elements damaged corrosion areas and loose rust. Next, with the help of welding, the pipe is grabbed to the previous place. Then you should fill the holes and cracks with segments of the wire or install a patch of sheet metal.

replacing the muffler

1. First of all, the WD-40 can be sprinkled on the fastening nuts of the silencer compounds, since they, as a rule, rust and drag it greatly, as a result of which it is quite problematic to unscrew such threads.
2. Next, using the key to 13, unscrew the nuts of the clamp. Use the ratchet handle and head to do everything most quickly and conveniently.
3. To unscrew the second nut to the end, since you can push the clamp.
4. Intripping the edges of the pipe with a flat screwdriver.
5. Next, kill the silencer with a hammer from the connection site towards the exhaust pipe.
6. At two points where the silencer is suspended, remove the pliers of spop.
7. At the last stage of dismantling, you must remove the silencer outside, for which we turn and unscrew the pipe in different directions.
8. Now install a new muffler in the reverse order.

repair of resonator

When the outer wall of the resonator bursts, some time you can restore the item. To do this, a thin and rusty metal is cut into the problem zone. It is advisable to make a simple rectangular cutout to make it easier to prepare the patch of the same size. Now we apply a patch to the resonator and boil around the perimeter.

repair of catalyst

With a violation of the tightness of the catalyst, it is necessary to replace this item. If there is an assistant, it is not rarely possible to replace without dismantling the muffler, for which it is necessary to carefully cut the catalyst with the help of a grinder. Next, we apply a new element to the pipe and welding. It is important to choose the correctly changing item, and not to be mistaken while working with grinders.
