What is 2 stroke engine & 4 stroke engine?

Question

Accepted Answer

A 2-stroke engine completes a power cycle in two strokes of the piston, while a 4-stroke engine completes it in four strokes.

2-stroke engine: Combustion occurs every revolution of the crankshaft.
4-stroke engine: Combustion occurs every two revolutions of the crankshaft.
2-stroke engines are simpler, lighter, and have higher power-to-weight ratio.
4-stroke engines are more fuel-efficient and have better emissions control.
Examples: 2-stroke - chainsaws, dirt bikes; 4-stroke - cars, motorcycles.

Accepted Answer

In a two-stroke engine, the spark plug fires every revolution, which is different from four-stroke engines. Similar to a four-stroke engine, fuel and air are mixed in the cylinder. The fuel/air mixture is compressed and pushed toward the spark plug by the piston – this is known as the compression stroke.

A four-stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake: Also known as induction or suction
