It is best to classify air particles from the aerodynamic properties as these properties determine the removal of them from the air, and where they deposit inside your breathing. 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.
