What Does Engine Stroke Mean?

[McPreston]

Engine stroke refers to the movement of the engine piston from one end of the cylinder to the other. Engines are categorized into two-stroke and four-stroke, also known as two-stroke and four-stroke engines. A complete engine cycle consists of intake, compression, power, and exhaust. Two-stroke engine: The piston moves from top to bottom and then from bottom to top, with the crankshaft completing one rotation. One full cycle of intake, compression, power, and exhaust is completed in one crankshaft rotation for a two-stroke engine. Four-stroke engine: The crankshaft completes two rotations to finish one cycle of intake, compression, power, and exhaust for a four-stroke engine. Engine: Refers to an engine with the same power output but smaller in size, quieter in operation, easier and cheaper to maintain with readily available parts, and lower maintenance costs. Under the same conditions, it has longer maintenance intervals, lower fuel consumption and failure rates, and a longer service life.
