DESCRIPTION
The Engine Piston Kit (Part Number: 4089736) for Cummins® commercial trucks is a crucial component of the engine. It includes the piston itself, piston rings, wrist pin, and retaining clips. The piston moves up and down within the cylinder, creating the necessary compression for combustion to occur. It is responsible for converting the force of expanding gases into mechanical energy, which powers the engine. The piston rings help to seal the combustion chamber and prevent any leakage of gases. The wrist pin connects the piston to the connecting rod, allowing the reciprocating motion. The Engine Piston Kit ensures efficient and reliable engine performance in Cummins® commercial trucks.
