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. Jonathan Brandstein, Patrice O'Neal's manager, said the family wanted to thank "all with the fans and friends who've expressed an outpouring of love and support for Patrice these past weeks." "Many folks have lost an end and loved friend; all individuals have lost a real comic genius' Jonathan Brandstein said in a very statement. Charlie Sheen who had previously been fired through the hit CBS comedy 'Two and a Half Men' in September tweeted: "The entertainment world as well as the world most importantly lost an excellent man. Patrice O'Neal would have been a regular guest for the program 'Opie & Anthony Radio Show' and would have been a familiar face at some New York City TV shows such as "Chappelle Show," "The Office," and "Tough Crowd with Colin Quinn. Patrice O'Neal's death was announced on Twitter by Opie from the Opie & Anthony Radio Show on Sirius/XM satellite radio: 'Yes, it's true that our pal Patrice O'Neal has gone by away,' Opie tweeted.
