Engine Piston Kit
Cummins®

The Engine Piston Kit, part number 4376355, made by Cummins®, is a crucial component of the internal combustion engine. It plays a vital role in the engine's power and performance. The piston kit consists of a piston, piston rings, piston pin, and circlips. The piston itself is a cylindrical component that moves up and down within the engine cylinder. It is typically made of high-strength alloy materials to withstand the extreme pressures and temperatures generated during combustion. The piston rings are positioned on the outer diameter of the piston and provide a seal between the piston and the cylinder wall, preventing the combustion gases from escaping and oil from entering the combustion chamber. The piston pin, also known as the wrist pin, connects the piston to the connecting rod, allowing the reciprocal motion of the piston. It must be strong enough to handle the forces exerted on it while maintaining a smooth operation. The circlips, or piston pin retainers, secure the piston pin in place, ensuring its proper functioning. In summary, the Engine Piston Kit, part number 4376355, manufactured by Cummins®, is a vital component of the engine that plays a significant role in converting the energy generated by the fuel-air mixture into mechanical power, allowing the commercial truck to operate efficiently and reliably.
