Understanding 2-Stroke Engines
2-stroke engines, also known as two-cycle engines, are a type of internal combustion engine that completes a power cycle in two strokes of the piston, or one rotation of the crankshaft. This is in contrast to four-stroke engines, which require four strokes of the piston to complete a power cycle. The simplicity and lighter weight of 2-stroke engines make them ideal for applications where power-to-weight ratio is critical, such as in motorcycles, chainsaws, and model airplanes.
Key Characteristics of 2-Stroke Engines
