Re: [PSUBS-MAILIST] Back to surface propulsion (generators)
How difficult a normal engine is to crank would have to do with the compression ration or how much pressure is built up in the combustion chamber. When you compress the air in a diesel engine, the compression produces heat. When the cold diesel fuel is injected into the hot (or warm) cylinder it causes spontaneous combustion.
Heat is a relative term. Takes 3 things to make a fire: Fuel, Oxygen, and heat.

My diesel Oldsmobile had two batteries and a 12-volt system. It
takes a lot of amps to squeeze diesel fuel enough to get it to
explode ... or so I understand.
Don't airplanes have 24v systems?
