So I have been wondering for some time now how our 3rd gen engines achieve EGR. I did some reading and found some generic descriptions of "in cylinder EGR". If I understood it correctly, the exhaust valve closes before TDC trapping exhaust gasses in the cylinder. Since we don't have any fancy active valve stuff on our engine I guess this is controlled by the cam. I also assume that this is the cause of lower economy and the carbon we get as well as the higher EGT we experience. Now for the questions. Is there anyone "in the know" that can confirm my assumptions? Who makes a cam that can put our engines back to a normal combustion cycle? Would any other supporting mods be required?
