Motorcycles:
* Gasoline engines: Most motorcycles, from small scooters to powerful sport bikes, utilize four-cycle gasoline engines.
Boats:
* Outboard motors: Many outboard motors on boats use four-cycle gasoline engines.
* Inboard motors: Some larger boats use four-cycle diesel engines for inboard propulsion.
Aircraft:
* Piston engines: Many small aircraft use four-cycle gasoline engines.
Other Vehicles:
* Generators: Four-cycle engines power many portable and stationary generators.
* Lawn mowers: Most gasoline-powered lawn mowers use four-cycle engines.
* Tractors: Many farm tractors use four-cycle diesel engines.
* Construction equipment: Excavators, bulldozers, and other construction equipment often employ four-cycle diesel engines.
* Forklifts: Some forklifts utilize four-cycle gasoline or diesel engines.
Note: While four-cycle engines are common, some vehicles also use two-cycle engines. Two-cycle engines are typically found in smaller, less powerful machines like chainsaws, lawn trimmers, and some small motorcycles.
