And "Reduced Heat Rejection," again should have been noted as a measure of the fact that your heat engine has a cooler fire inside it with EGR. What we'd like to do is make the MOST heat, and get the most out of that heat, with the smallest amount of fuel, emissions aside.

Mechanic, I'm not picking on anyone, and anyone reading Mr. Webb's posts can see he's a smart guy.
Well, am engine is actually more efficient with a wide open throttle. Putting your foot to the floor in a standard car is an entirely different scenario, also, that is what you do basically with "pulse and Glide" to reduce consumption. I also wonder about the "heat rejection" part.
