what is a stroke engine
Each of these is called a stroke. The term is also used to mean the length of the stroke. In a steam locomotive, or in a steam, Otto, Diesel or piston engine, a stroke is the action of a piston travelling the full length of its locomotive cylinder or engine cylinder in one direction. The stroke length is determined by the cranks on the crankshaft. Stroke can also refer to the distance the piston travels.
