Engine Piston Kit
Cummins®

The Engine Piston Kit (Part Number: 4955576) for Cummins® commercial trucks is a crucial component of the internal combustion engine. This kit includes one or more pistons, along with the necessary rings, pins, and retainers. The piston is typically made of high-strength alloy or cast iron and acts as a moving component inside the cylinder. Its primary function is to convert the energy generated by the combustion of fuel into mechanical force. When the fuel-air mixture ignites within the cylinder, the piston is forced downward by the expanding gases, transmitting power to the crankshaft. The piston moves up and down within the cylinder, creating a controlled combustion process. The piston rings help to seal the combustion chamber, preventing excessive leakage of gases and oil into the crankcase while also regulating lubrication. The piston pin connects the piston to the connecting rod, allowing it to move smoothly. In summary, the Engine Piston Kit (Part Number: 4955576) for Cummins® commercial trucks plays a crucial role in the engine's power generation process by converting the energy of combustion into mechanical force through controlled piston movement.
