In the terminology of drivers and the auto show, the word muffler often means the entire complex of chambers and pipes, which are included in the exhaust system of the modern vehicle, hence the name - the silencer resonator. Independent replacement of a faulty resonator is a rather time-consuming event, but quite fulfilled at home. It is worth noting that due to the characteristics of the design of the resonator, it cannot be repaired, so the only way out when the breakdown is a replacement for a new one. About this further in the article.

Exhaust system of VAZ 2114, from which major parts the exhaust system consists

The exhaust system by car VAZ 2114 consists of the following main elements:

1. The exhaust pipe that is attached directly to the graduation collector and takes on the entire main vibration, chemical and fiery blow from exiting spent gases. That is why it is made only from high strength, alloyed steel.
   
2. Catalyst, the purpose of which is to hone the excess oxygen in its cells, made in the form of peculiar ceramic cells. Their surface is covered with a platinumiridium layer, when in contact with which oxidation and driving reaction occurs, as well as reducing the level of toxicity of passing exhaust gases.
   
3. The resonator, which in some sources is called an additional silencer, however, this designation is not accepted in professional circles.
   
4. The muffler - plays the role of residual sound absorption, as well as the output of the toxic gases of the exhaustion beyond the bodies of the vehicle.

An additional silencer, or a resonator 2114, for which it is needed, what tasks do

The resonator is an essential part of the exhaust vehicle exhaust system. Its main task is to reduce the noise level produced by incoming exhaust gases. Another, no less important task is to smooth the vibrations, which arise as a result of the performance of the power unit, and the creation of the direct flow of gases, which is necessary to prevent the appearance of the oppression in the receiving pipe, as this would significantly reduce the power of the motor.

Structurally, it is made of four cameras through which perforated pipelines pass. They also perform connecting functions for chambers of the resonator. As for perforation, it consists of a specific hole, precisely calculated size. The tubes and walls of the chambers are a resonant steam having its own frequency of oscillations, which differs from the frequency of oscillations of exhaust gases. And the frequency data is different in each chamber. As a result, there are smoothing of mass low-frequency oscillations, alignment of flow directions and arrangement of medium and high-frequency vibrations.

Signs of an additional muffler malfunction (resonator)

As a result of operation in such an aggressive medium (exhaust gases have extremely high chemical activity and temperature) and in conditions of high vibration, the resonator is not rarely disretened. Signs of such faults are as follows:

1. Razing and ringing sound from under the bottom of the car. About such a sound also say - the silencer rattles. As a rule, this is the consequence of the fact that the inner department of the resonator burned out and even collapsed, and small elements chat somewhere in the stream of gases.
2. The volume of leaving gases increases, since the breakdown resonator does not perform its functions.
   
3. Possible reduction in motor power as a result of violation of the geometry of internal surfaces, as well as a significant braking of expire gases.

Criterion for choosing a new resonator

Double-housing resonators last longer. It is important that the material is unresponsive to corrosion. Usually, inexpensive silencers are made of aluminated steel, i.e., ordinary steel coated with a small layer of aluminum, which protects the surface from corrosion. However, when buying such a resonator, it should be remembered that the small cost of the product is obtained by reducing durability. The best resonators are made of stainless steel. An equally important role is played by the volume of the resonator. This indicator affects the effectiveness of its work. When the volume is not enough, with a sharp press on the gas pedal, the noise will be significantly intensified, and the element itself can begin to vibrate.

Choosing a workplace

The replacement of the resonator on the VAZ 2114 must be carried out on the overpass or the observation pit.

Tools, fixtures, consumables

To replace the resonator, you will need the following tools and devices:

1. Keys on "17" (two pieces).
2. Key amplifier.
3. New gasket resonator.
4. Sealing metal rings.
5. Clamps with fasteners.
6. WD40 liquid.

How to replace an additional silencer (resonator) Step-by-step instructions

1. The connecting bolts and tightening clamps on both sides of the resonator are applied WD40 liquid and give it time so that it can penetrate all the slots (about 10-15 minutes).
2. By a catalyst, install the stand in advance so that after dismantling the clamps that connect the resonator with the catalyst, it does not like that it may cause damage to the fasteners with the receiving pipe. In the same way, we make a stand under the resonator, because it will need to be unscrewed on both sides.
   
3. We take pre-prepared keys and turn the fastenings from the catalyst. Be prepared for what you need to make a fairly great effort.
4. We unscrew the mounts from the silencer, thereby freeing the gasket between the resonator and the silencer.
5. We dismantle the old resonator.
6. When installing a new resonator, first tighten the fastening bolts from the catalyst side, but not completely.
   
7. Next, we connect the muffler with the resonator, in advance inserting a new sealing ring. During the connection, check the laying density of the gasket, in order to avoid leakage of exhaust gases.
8. We reach the fastening bolts from the catalyst.

Tips Pros: What parts are changed additionally when replacing the resonator

In the process of replacing the resonator, it is desirable to replace rubber suspensions that reduce the vibrations of the muffler when the vehicle is moving.
