Question

Accepted Answer

2-stroke engines have power strokes every revolution, while 4-stroke engines have power strokes every other revolution.

2-stroke engines have a simpler design with fewer moving parts compared to 4-stroke engines.
2-stroke engines require a mix of oil and fuel for lubrication, while 4-stroke engines have a separate oil reservoir.
2-stroke engines are lighter and produce more power for their size, but are less fuel efficient and emit more pollution compared to 4-stroke engines.
Examples: 2-stroke engines are commonly used in chainsaws, motorcycles, and some small boats, while 4-stroke engines are found in cars, trucks, and larger boats.
