What is 2stroke?

A 2-stroke engine is a type of internal combustion engine that completes a power cycle in two strokes of the piston, or one crankshaft revolution. It combines the intake and compression processes in one stroke and the power and exhaust processes in another, allowing for a simpler design and lighter weight. This type of engine is commonly found in smaller applications, such as motorcycles, chainsaws, and lawn equipment, due to its high power-to-weight ratio. However, 2-stroke engines are generally less fuel-efficient and produce more emissions compared to their 4-stroke counterparts.
