How many rotations of the crankshaft are required to complete each stroke of a?

In a four-stroke engine, the crankshaft completes two rotations to complete one full cycle of all four strokes: intake, compression, power, and exhaust. This means that each stroke of the engine corresponds to half a rotation of the crankshaft. Therefore, for each individual stroke, one full rotation of the crankshaft is required for two strokes.
