An EGR valve, that stands for Exhaust Gas Recirculation. As the name suggests, this valve is responsible for sending the exhausted air back in to the combustion chamber. This exhausted air is much warmer than the incoming air, thus it helps the engine in starting up quickly because the fuel and the air does not need to be heated up as it is already warmed by the valve. This causes the engine of the car to work efficiently and smoothly.
The EGR valve is situated in the center of the engine and it creates a small opening between the exhaust fan and the manifold. This allows the exhausted air to be re circulated back in to the engine which reduces any combustion air that could otherwise cause the engine not to work properly. The valve helps in controlling the creation of nitrogen oxides which are harmful.
In latest cars, the EGR valve is electronic using a small stepper motor. It is important the valve remains close when the engine is cold and not in uses other wise it can get clogged. Only when the engine has warmed up, then the valve should be opened.
Many a times the valves get clogged with dirt particles and combusted air which causes the car to come to a halt and stop. In such cases either the valve is cleaned with cleaners and if it does not work, then the valve has to be replaced with a new one.
