		Definition of piston engine in English: piston enginenoun An engine, especially in an aircraft, in which power is derived from cylinders and pistons rather than a turbine. 活塞发动机 Example sentencesExamples -  How did a piston engine tanker refuel a faster jet bomber?
 -  Jet engines have supplanted piston engines in commercial aircraft due to more power, greater speed, and better all-around performance.
 -  The basic design of the aviation piston engine hasn't changed drastically in decades.
 -  An old generation piston engine is nowhere near as technically reliable as a new generation high tech turbine aircraft engine.
 -  This type of powerplant was ideal for lower performance aircraft that could substitute their piston engines for the turboprop.
 -  H - 21s were powered by 1,425-horsepower radial piston engines and could carry 20 soldiers.
 -  Hitherto, helicopters had been powered by piston engines and this had brought many cooling problems.
 -  Wankle rotary engines use the Otto cycle, but they do it in a very different way than four-stroke piston engines.
 -  The operation of the rotary engine means that it is not prone to backfiring on hydrogen, as conventional piston engines are.
 -  The combination is a small, low-pressure steam boiler feeding a piston engine or turbine.
 -  Jet engines are crucial: They're faster than piston engines and far safer.
 -  They replaced the old radial air-cooled and liquid-cooled engines with a high-compression piston engine.
 -  Improved engine designs have boosted efficiency - turbines replaced piston engines, for example.
 -  One seemed to live and dream, aircraft and to this day I automatically crane skywards at the sound of a piston engine.
 -  A self-winding hose reel called ReelSmart lets you flip a switch to divert the water flow from the hose to a piston engine inside the drum.
 -  As in a piston engine, overlap is the short circuit by which spent gasses invade the fuel-air charge.
 -  Unlike a piston engine, where reciprocating parts move up and down, the twin rotors in the Mazda just spin around.
