diesel engine

Sparkless combustion powerplant

A diesel engine is an internal combustion engine that ignites fuel through compression rather than spark plugs.

Air is compressed until it becomes hot enough to ignite injected fuel spontaneously.

Diesel engines power heavy vehicles, ships, generators, and industrial equipment, offering greater fuel efficiency and torque than gasoline engines: The truck's diesel engine could haul forty tons up the mountain grade.
