The Two-Stroke Cycle is a type of internal combustion engine cycle that completes a power stroke in just two movements of the piston, or one crankshaft revolution. This cycle consists of two main strokes: the compression stroke and the power stroke. During the compression stroke, the fuel-air mixture is compressed, and then it is ignited, causing an explosion that pushes the piston down during the power stroke. Two-stroke engines are commonly found in small machinery, such as chainsaws and lawnmowers, due to their lightweight and simple design. However, they are generally less fuel-efficient and produce more emissions compared to four-stroke engines, making them less suitable for larger vehicles like cars and trucks.
