What are the four strokes of a four-stroke engine?

[Kyle]

Four strokes are: intake stroke; compression stroke; power stroke; exhaust stroke. The following is an introduction to the four strokes: Introduction: A cycle consists of four strokes, or the unidirectional linear movement of the piston in the cylinder. Principle: In most four-stroke engines, the valves simply close with the return of the spring. As the engine speed increases, the time for the spring to push the valve to open and close will change, and this change in time is not conducive to the performance of the engine. The disadvantage of this system is its high complexity and cost. Some manufacturers use it in the Ducati system for motorcycle engines.
