four-stroke cycle engine

four-stroke cycle engine: An engine requiring two complete revolutions of the crankshaft to fire each piston once. The first stroke down (intake stroke) pulls fuel and air into the combustion chamber. The second stroke up (compression stroke) compresses the mixture. The third stroke down (power stroke) comes about through the rapid burning of the compressed fuel mixture. The fourth stroke up (exhaust stroke) expels the exhaust gases from the cylinder. It is also called the "Otto cycle."
