The concentration of their language When a plan is finally formulated it usually looks something such as this; you are going on a diet of some sort and if you're really motivated attempt an exercise program. This makes sense because everybody knows the fewer calories we take in the more fat we could lose. Add jogging a couple of times a week and some sit-up and eventually that rebellious stomach is going to be put in its place. 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.
