So the combustion heat is spread out over more mass, and the temperature is lowered as a result. That answers my question.
This is an 88 Accord BTW. It's a feedback carb, set rich internally, with small amounts of air introduced under ECU control downstream of the throttle. EGR is controlled...
Thanks for the response. Good point about the EGR gas temp. So let's assume the throttle valve is opened enough to restore the original air mass, and torque. Now, with the addition of exhaust gas, the pressure, and so the temperature, inside the cylinder is even greater at the top of the...
Hello,
If I have gasoline engine at part throttle, and open the EGR valve, can I assume, holding throttle constant, a rise in manifold absolute pressure?
Does this nonetheless increase the total mass of gas entering the cylinders? while reducing mass of fresh air?
Thanks in advance..
