Re: Diesel engine.

A steam engine can be very efficient

It can't. All heat engines are thermodynamically limited to a peak maximum efficiency of 1 - TC/TH.

For a steam engine, you're never going to get TH above about 400K, and TC is going to be around 300K, so you're left with a theoretical peak efficiency of about 25%.
