The EGR system routes many of the exhaust gases (6 ? 10%) through the EGR valve, last on the Intake System, and in the end in the combustion chamber. The exhaust gases are inert i.e. they don't burn within the combustion chamber; also, the exhaust gases use up a number of the space which could preferably be taken with the intake air. This decreases the volume of intake air available for the combustion process during each Power Stroke; which experts claim decreases the peak combustion temperatures. This leads to 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.
