A four-stroke engine can also be referred to as a four-cycle engine, as it completes four distinct stages - intake, compression, combustion, and exhaust - during one complete cycle. Other synonyms for this type of engine include spark-ignition engine, as gasoline is typically used as fuel and ignited with a spark plug, and reciprocating engine, as its pistons move up and down in a reciprocating motion. Additionally, some may refer to it as a internal combustion engine, as it burns fuel within the engine itself to generate power. Regardless of the terminology used, four-stroke engines are commonly found in a wide variety of vehicles and machines, including automobiles, motorcycles, and lawnmowers.
