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. The first thing you should do before getting into building your butt is always to jot down a strategy detailing which exercises you'll need to do, what foods to nibble on, what time you'll retire for the night and which days you'll workout. These factors are crucial in that it may help you overcome obstacles that lay within your way like deficiency of motivation, peers putting you down and discouraging from reaching your goals, not enough some time and procrastination.
