Exhaust System car parts - all important information about operating method, mounting, diagnostics and service life

The exhaust system of the car is a complex combination of structural elements, which is aimed to guide exhaust gases away from the cylinders of the engine, to reduce cylinders temperature, to ensure the lowest level of harmful pollutants and to reduce exhaust noise from the engine of the vehicle.

The structure of the exhaust system of the engine
  • Exhaust manifold. Releases cylinders of the engine from exhaust gases.
  • Oxygen sensor. Can be mounted before the exhaust catalyst, after it, as well as before and after. Measures the proportion of oxygen in the exhaust gas.
  • Catalytic converter. It reduces the amount of toxic pollutants in the exhaust gases, such as carbon monoxide, hydrocarbons and oxides of nitrogen.
  • Particulate filter. It is presented in the exhaust system of vehicles with diesel engine. It removes soot from the exhaust gas of a diesel engine.
  • Muffler. It converts the exhaust gases energy, reduces the amount of noise.
  • Connecting pipes. Connect different elements of the system together.
Exploitation

Due to constant interaction with aggressive environment, determined by the location of the exhaust system, and high temperature impact factor, the exhaust system elements are characterized by higher level of deterioration. The service life time depends entirely on the quality of parts. Elements made of stainless steel, are able to serve 10-15 years. Service life of details made of aluminized steel will last 3-6 years.

As concerning items made of common steel, their service life does not exceed 1.5-2 years. Besides, you should not forget about the importance of the correct operation of the catalytic converter. When using the high-quality fuel it is able to overcome from 100 thousand up to 200 thousand kilometers. By properly operating catalyst the service life of a muffler is 5-6 years. The absence of this element reduces the service life of a muffler to 1-2 years. If you replace the converter by the flame arrestor, the muffler will be properly operating for 2-3 years.

Signs of exhaust system failure
  • Vehicle does not start, or stalls quickly.
  • No engine power, low acceleration, engine turns over slowly.
  • High fuel consumption.
  • Error "Check Engine" on the instrument board.
  • Exhaust gases are leaking inside the car.
  • The presence of soot on the muffler.
Causes of failure
  • Infringement of tightness caused by mechanical damage or incorrect connection of the details.
  • The vehicle is being used under unfavorable conditions (the excessive use of roadway de-icers and anti-icers, humid climate, the poor quality of the road surface).
  • Gas distribution mechanism failure.
  • Use of low quality fuel.
Repair of the exhaust system

The major nuance by repair work is the degree of complexity of the exhaust system damage. If you are faced with the problem of the quality of attachment, you can repair this failure yourself. Moreover, many motorists are not even afraid of infringement of tightness of components as a result of damage. Typically, this failure is being removed by using welding. But it is necessary to remember that the gases temperature, roadway de-icers and anti-icers and high humidity will not allow a repaired item to operate as long as you want.

Replacement of the exhaust system

In order to give the car its former flawless condition, it is reasonable to choose detail replacement instead of its repair in case of complex faults in exhaust system. New high-quality parts will let you forget the problem for a long time. In addition to it, the structure of the exhaust system allows you alongside with replacement of all elements at once, also to replace only those items that are really required. It is always better to let professionals acquire and install the spare parts.
