The EGR system routes a number of the exhaust gases (6 ? 10%) through the EGR valve, back in for the Intake System, and finally inside combustion chamber. The exhaust gases are inert i.e. they do not burn inside the combustion chamber; also, the exhaust gases occupy a few of the space which may otherwise be taken from the intake air. This cuts down on level of intake air readily available for the combustion process during each Power Stroke; which often decreases the peak combustion temperatures. This ends in lower NOx emissions. I've stood a weight problem all my life. My parents bought me "huskies" while I would definitely grammar school. I wasn't an incredibly active kid. My parents always provided 3 good meals for me daily. School lunches were actually nutritious in those days. They weren't anything as if they are now with pizza, tacos, hamburgers, hot dogs, chips, sweet sodas and many types of kinds of chips and desserts. I hear chips are the main course especially with school girls. Today's kids don't have the opportunity.
