The EGR system routes a number of the exhaust gases (6 ? 10%) from the EGR valve, last on the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they cannot burn in the combustion chamber; also, the exhaust gases take up a number of the space which would preferably be taken with the intake air. This reduces the volume of intake air readily available for the combustion process during each Power Stroke; which in turn decreases the peak combustion temperatures. This brings about lower NOx emissions. The automobile is really a complex machine comprised of different components each which has a specific role. Fuel is processed inside the engine where it really is changed to souped up that moves the vehicle. Exhaust in the combustion process is filtered to render emissions less unhealthy for environmental surroundings. The transmission system feeds more capability to the engine for the automobile to boost its acceleration.
