Knowra Piston engine Piston engine A piston engine produces power through pistons moving back and forth inside cylinders. Combustion or another pressure source drives the pistons, whose motion is converted into rotation or other useful work.
Four-stroke engine : An internal-combustion engine that completes intake, compression, power, and exhaust strokes over two crankshaft revolutions. Its four piston strokes form the standard cycle used in many piston engines.
Cylinder (engine) : A chamber in an engine in which a piston moves and, in many engines, a fuel-air mixture burns. Its bore guides the piston and contains the working pressure.
Wankel engine : A rotary internal-combustion engine that uses a triangular rotor moving within an epitrochoidal housing. It produces power without reciprocating pistons, avoiding their characteristic motion and components.
Automobile engine : An engine designed to propel a road vehicle, commonly using gasoline or diesel fuel. Road cars are the most familiar application of piston-engine power.
Automobile : A road vehicle designed primarily to carry people and powered by an engine or electric motor. Compact piston engines made widespread self-propelled road transport practical.
Two-stroke engine : An internal-combustion engine that completes a power cycle in one crankshaft revolution, using ports or valves to exchange gases. It combines gas exchange and compression into fewer piston strokes than a four-stroke engine.
Piston : A close-fitting moving component that slides within a cylinder and transmits pressure through a connecting rod. It receives force from gases and carries that force to the crank mechanism.
Gas turbine : A rotary engine that extracts power from a continuous flow of hot gas through turbines. Its continuous rotary flow contrasts with the piston engine's repeated cylinder cycles.
Aircraft piston engine : A reciprocating internal-combustion engine designed to propel an aircraft through a propeller. It adapts piston power for aviation, where weight and altitude performance matter.
Internal combustion engine emissions : Gases and particles released when fuel burns in an internal-combustion engine. Piston-engine exhaust contributes pollutants and greenhouse gases, depending on fuel and operation.
