The Engine Piston Kit (Part Number: 4376345) for Cummins® commercial trucks is a crucial component of the internal combustion engine. Specifically designed for EPA13 Automotive 6.7liter ISB/QSB engines 2007.5-2018. It consists of a piston, piston rings, piston pin, and circlips. The piston is a cylindrical metal component that moves up and down within the engine cylinder. It serves the primary function of converting the energy generated by the burning fuel-air mixture into mechanical energy, which drives the vehicle's crankshaft. The piston rings provide a seal between the piston and the cylinder wall, ensuring efficient combustion and preventing leakage of gases. The piston pin connects the piston to the connecting rod, allowing the reciprocating motion of the piston to transfer power to the crankshaft. The circlips secure the piston pin in place. Overall, the Engine Piston Kit is essential for proper engine function, combustion efficiency, and reliable power delivery in Cummins® commercial trucks.
