Engine Piston Kit
Cummins®

A piston kit is a set of components used in the internal combustion engine of a truck. The engine piston kit includes a piston, piston rings, and wrist pin. These parts work together to transfer energy from the expanding gases in the engine's combustion chamber to the crankshaft. The piston moves up and down inside the cylinder, compressing air and fuel during the intake stroke and then igniting it during the power stroke. The piston rings seal the gap between the piston and cylinder wall to ensure efficient combustion and prevent oil from leaking into the combustion chamber. The wrist pin connects the piston to the connecting rod, which transfers power from the piston to rotate the crankshaft. A well-functioning engine piston kit is crucial for optimal engine performance and reliability in heavy-duty trucks like those used for hauling cargo or towing trailers on long-distance routes.
