As a general definition we can say that the EGR valve is component of the exhaust emission control system of the vehicle. This vehicle piece is very intricate and specific but it has a very vital function which makes the vehicle engine work with a much higher efficiency as well as helps avoiding that vehicle gases affect the environment.
EGR is a short form for Exhaust Gas Recirculation and this name directly refers to its responsibility. This valve transfers exhaust gases back into the combustion chamber by redistributing them through the intake manifold air stream. This way, this valve mainly functions by taking exhaust gases to the best place.
Through this valve, the vehicle engine’s combustion chamber readmits exhaust steam assisting reduce peak combustion chambers and engine emissions. This way, the EGR valve has the Oxides of Nitrogen reduction as its main work. It avoids the way in which gases created from the automobile engine could damage the environment once they enter in contact with the atmosphere. This way, the EGR valve serves as help to the engine’s economy as well as it helping it work more efficiently and prevents gases from damaging the environment.
It is very vital to maintain the EGR valve clean since it can easily become obtruded by dirt because of the way in which exhaust gases are constantly passing by it. This way, one of this vehicle piece’s main weak points is the appearance of dirt impeding the correct pass of gases through it. You should make sure the valve is always clean and devoid of dirt or any other element which could be an obstacle for its proper operation.
Apart from the way in which it helps the vehicle engine to work more efficiently, the EGR also adds to the environment since it keeps car gases from causing smog. This way, it is imperative to have this car unit working properly, but in case it is broken you should remember that this valve usually is an electronic car unit and therefore if it is broken you should not try to fix it yourself unless you are sure of what you are doing.
