The vessel imploded and from what I understand the sudden compression results in a diesel detonation whereby everything combustible is vaporized.
I don't believe you are insinuated that this sub was powered by diesel you are just describing the concept of compression ignition. FWIW, the compression cycle of diesel engines is about 400 psig. The compression cycle of gasoline engines are less than 200 psig. On a four cycle engine every fourth cycle the spark plug ignites. The other three cycles the fuel is ignited by compression. If engines were perfectly adiabatic spark plugs would not be needed after startup.

Yes. I know its not a diesel submersible.
I meant the phenomenon that compression creates heat.

The hull collapsed so quick that the pressure spike turn it into a combustion chamber. Nothing to do with propulsion.

That is not how a four cycle engine works.
