Thats the wrong way round. They are generall cases of which the real life machines are special cases.
Loosemore is saying that RL is a special case that doesn’t generalise.
I’m not sure that I agree that a real car engine is a special case of a Carnot engine; I think the general case is a heat engine, of which a Carnot engine is a special case that is mathematically convenient but unattainable in physical reality.
