Treb I have that textbook.
I like it, but I had forgotten that it had HCs in the tables.
Our rub is not that it matters between high heat and low heat. Our only issue is that your engine is given this much energy but it can only usefully extract this much. IF we count up all the little pieces of energy that come out the other side its the same as went in, but the point is electric fuel delivery systems and electric engines are more efficient by far than HC fuel delivery systems and ICE engines.
What is worth mentioning is that even a Carnot cycle would be less capable than an EV(cycle and chains included, or not). So if the absolute most efficient heat engine with absolutely no irreversibilities cannot compete, no real engine is even worth talking about. A real engine if its lucky will get 50% of what the ideal theoreticaly will get.
