Silencer is an important structural component of the exhaust system. Functioning of the modern car is impossible without this car part. The silencer has several functions. First, it reduces the noise level of exhaust gases. Secondly, it converts the energy of exhaust gases and reduces their speed, temperature and pulse. That exhaust gases that leave the engine cylinders have high pressure. But the movement of gases in the exhaust system creates sound waves that spread faster than gas. The muffler also converts into thermal energy sound vibrations, thereby reducing the noise level to a desired one. At the same time this creates pressure in the exhaust system that reduces engine power.

In order to reduce noise level, there are used multiple technologies, such as expansion of the flow, changing the flow direction, the interference of sound waves and the absorption of sound waves. The flow expands using multiple chambers of different sizes, which are separated by partitions. This effectively suppresses low-frequency sound waves. Flux depression and expansion in the muffler is possible due to diaphragm hole or throttle. It is also worth noting that in addition to straight silencers, car muffler includes changing the direction of flow of exhaust gases, which allows reducing medium-and high-frequency sound waves.

To date, in cars there are set from one to five silencers. As a rule, there are two silencers. That silencer, which is located closer to the engine, is a pre-muffler or resonator, followed by the main or rear muffler. It is important to remember that each specific set of mufflers corresponds to an individual car model. When the silencer fails, do not hurry to order the spare part in the car workshop. It will be far cheaper and faster to order this part in our online shop. It is the place where you will always find brake discs, exhaust valve or distributor rotor.
