Which propulsion type is Diesel?

Explanation:
Diesel propulsion is about engines that run on diesel fuel and use compression ignition. In a diesel engine, air is compressed to a very high temperature, and the injected diesel fuel ignites automatically without a spark. This is different from petrol (gasoline) engines, which rely on a spark plug to ignite a petrol–air mixture, and from electric propulsion, which uses electric motors powered by batteries or grids. So, the term Diesel identifies the propulsion type as the diesel engine. The other terms describe different propulsion systems and aren’t diesel.
