Caution: Use of non-original parts from the manufacturer may cause problems with overall handling characteristics.
In the exhaust system, the exhaust gases are "cleaned" of harmful components in the catalytic converter (nitrogen oxides, carbon monoxide and hydrocarbons), muffler and resonator (exhaust noise).
Individual components of the exhaust system can be secured with clamps or have a flange connection with or without a gasket.
Brackets and rubber insulators take the weight of the exhaust system, providing vibration damping of the exhaust system and eliminating impacts of system parts on the body. In addition, there is compensation for changes in the length of the exhaust system parts during heating and cooling.
To prevent damage to individual vehicle parts from overheating, heat shields are used in the exhaust system.
The exhaust system may consist of the following parts:
- Catalytic converter
- Brackets
- Heat shields
- Insulators
- Exhaust manifolds
- Exhaust noise muffler
- Exhaust pipe
- Resonator (if installed)
- End pipe of the muffler (if installed)
- Catalytic converter
A catalytic converter is a device for reducing the toxicity of exhaust gases, such as reducing the level of hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxides (NOx) emissions. The catalytic converter consists of a monolith of porous ceramics installed in a sheet metal shell. The ceramics are coated with three noble metals:
- Palladium (Pd)
- Platinum (Pt)
- Rhodium (Rh)
The neutralizer is not serviced or repaired.
Muffler
The exhaust silencer reduces the noise level to an acceptable level.
Resonator
Some exhaust systems may be equipped with a resonator (before or after the muffler). Installing a resonator as a reactive noise muffler allows you to reduce the overall hydraulic resistance of the exhaust system.
