Trích: This is not a disadvantage regarding the power because, in contrast to the four-stroke cycle, every revolution in the two-stroke engine is a working stroke; therefore, power-to-volume ratio appears to be some 1.4–1.6 higher than in four-stroke engines, while the weight-to-power ratio is about 0.44–0.5 lower for the two-stroke engines.
