Engine characteristics: In one engine working cycle, the crankshaft rotates twice (720 degrees). Each stroke corresponds to a half-rotation of the crankshaft (180 degrees). The intake stroke occurs with the intake valve open, while the other two strokes keep both intake and exhaust valves closed. Among the four strokes, only the power stroke generates driving force.
