Difference between 2 stroke engine and 4 stroke engine

Question

Accepted Answer

2 stroke engines have a simpler design and produce more power, but are less fuel efficient and emit more pollution compared to 4 stroke engines.

2 stroke engines complete a power cycle in 2 strokes of the piston, while 4 stroke engines complete it in 4 strokes.
2 stroke engines do not have valves, while 4 stroke engines have intake and exhaust valves.
2 stroke engines require a mixture of fuel and oil, while 4 stroke engines use separate fuel and oil systems.
2 stroke engines are commonly used in small power tools, motorcycles, and boats, while 4 stroke engines are used in cars, trucks, and larger machinery.

Accepted Answer

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.
