The word is composed of 'Diesel' and 'Motor' (engine). 'Diesel' is the name of the inventor Rudolf Diesel. The word therefore refers to an engine that works according to the principle he developed.

Common adjectives are 'kraftvoll' (powerful), 'sparsam' (fuel-efficient), or 'leistungsstark' (high-performance). Typical verbs are 'einbauen' (to install), 'entwickeln' (to develop), or the phrase 'mit einem Dieselmotor ausgestattet sein' (to be equipped with a diesel engine).

In a technical context, 'Diesel' can be short for the diesel engine. 'Dieselmotor' is the precise and clear term for this engine. So both words can mean the same engine. In everyday speech, people sometimes say the shorter 'der Diesel', especially when it is clear that they are talking about the engine. In a workshop, technical context, or explanation, 'Dieselmotor' is more precise and less ambiguous, because 'Diesel' can also mean fuel or a vehicle.
