If you’d like to learn more about Wiseco 4-stroke pistons, check out the answers to our most frequently asked questions below.
2-stroke pistons operate in engines that complete a power cycle in two strokes of the piston (one crankshaft rotation), making them simpler and more lightweight but often less durable. 4-stroke pistons, on the other hand, work in engines that complete a power cycle in four strokes (two crankshaft rotations), resulting in more efficient combustion and better emissions control.
A 4-stroke engine operates through four stages: intake, compression, power, and exhaust. During the intake stroke, the piston moves down, drawing in a fuel-air mixture. In the compression stroke, the piston moves up, compressing this mixture. The power stroke occurs when the spark plug ignites, forcing the piston down and generating power. Finally, the piston moves again in the exhaust stroke, expelling exhaust gases. This cycle repeats to produce continuous power.
Choosing the right 4-stroke piston involves considering factors such as engine type, bore size, compression ratio, and specific application (e.g., racing, off-road, street). Wiseco provides a variety of options tailored for different engines and uses.
With over 80 years of experience, Wiseco has perfected the art of piston manufacturing, utilizing advanced 3D design techniques and high-quality forged materials to ensure each piston meets the highest standards.
