Upstroke (ignition/compression): The piston goes up, air and fuel enter the crankcase.This process requires fewer moving parts for easier maintenance, but it does provide less torque. Exhaust: The exhaust valve opens, and the exhaust gases exit the cylinder.Ī two-stroke engine combines the compression and ignition steps on the upstroke and the power and exhaust steps on the downstroke.Power: After the fuel is compressed, it is ignited to produce the engine’s power.Compression: As the piston moves upward, the fuel is compressed.Intake: The intake valve is open, and fuel is drawn in with a downward stroke.4-Stroke Engineįour-stroke engines are fuel-efficient and environmentally-friendly. This means a 2-stroke engine can potentially produce twice as much power as a 4-stroke engine and also weigh less. The main difference between a 4-stroke engine and a 2-stroke engine is that a 4-stroke engine goes through four stages, or two complete revolutions, to complete one power stroke, while a 2-stroke engine goes through 2 stages, or one complete revolution, to complete one power stroke.

While you may have heard of these types of engines before, you may be asking yourself what the difference is between them.
Throughout the many changes and innovations in automotive and engine design, one thing has remained a constant - the design of two-stroke and four-stroke engines.
