Piston for Mercedes-Benz OM401

The piston A4030300617 functions as a central component within the combustion assembly of Mercedes-Benz OM401 and OM402 engines. It moves reciprocally within the cylinder to compress the air and fuel mixture and transmits the force generated by the combustion process to the crankshaft via the connecting rod. The component features integrated grooves designed to accommodate piston rings, which maintain a seal to prevent gas leakage and manage oil consumption during engine operation.

This part is compatible with Mercedes-Benz OM401 and OM402 engine models. It is manufactured to meet the specific dimensional and functional requirements of these engine series to ensure proper fitment and operation within the cylinder bore.

In internal combustion engines, the piston acts as a movable plug that seals the combustion chamber. It must withstand the high pressures and temperatures generated during the power stroke while maintaining a sliding fit against the cylinder wall. By converting the energy from the expanding gases into mechanical motion, the piston enables the engine to generate torque and power for the machinery.
