Comedian and radio personality Patrice O'Neal died at 41 at the New York-area hospital on Tuesday morning due to a stroke he suffered last October following a long fight with diabetes. Patrice O'Neal is survived by his wife, Vondecarlo Brown, his stepdaughter, Aymilyon, his sister, Zinder, and the mother, Georgia. The EGR system routes a few of the exhaust gases (6 ? 10%) through the EGR valve, back in towards the Intake System, and ultimately within the combustion chamber. The exhaust gases are inert i.e. they do not burn in the combustion chamber; also, the exhaust gases undertake a few of the space which may preferably be taken with the intake air. This reduces the quantity of intake air available for the combustion process during each Power Stroke; which decreases the peak combustion temperatures. This results in lower NOx emissions.
