DESCRIPTION
The engine piston (part number 3070706) is a crucial component of the Cummins® commercial truck engine. It is a cylindrical metal piece that fits snugly within the engine cylinder. The piston moves up and down within the cylinder in response to the engine's combustion process. Its primary function is to convert the energy generated by fuel combustion into mechanical motion. As the fuel-air mixture ignites, it exerts pressure on the piston, pushing it downward. This motion transfers energy to the crankshaft, which eventually powers the wheels of the vehicle. The piston also plays a vital role in sealing the combustion chamber, maintaining compression, and controlling fuel combustion within the engine. Overall, the engine piston is a fundamental part of the Cummins® commercial truck engine, ensuring efficient energy conversion and effective engine performance.
