A pop-up piston is a specialized piston design used in some chainsaw engines. Unlike traditional pistons that have a flat top, pop-up pistons feature a raised center section. This design allows for a higher compression ratio within the combustion chamber. When the piston moves upward in the cylinder, the raised center section compresses the fuel-air mixture more intensely than a traditional flat-top piston. This increased compression leads to a more powerful explosion and greater torque output.
