Piston for Mercedes-Benz OM611

The piston with part number 87-136400-00 is a component for the Mercedes-Benz OM611 diesel engine. It functions as the moving boundary within the cylinder, compressing the air-fuel mixture and receiving the force generated by combustion to drive the crankshaft through the connecting rod. This component ensures the necessary seal against the cylinder walls to maintain compression and manage combustion gas pressures during engine operation.

This part is compatible with the Mercedes-Benz OM611 engine. It is engineered to meet the specific dimensions and tolerances required for this engine series. Proper installation of the piston is required to maintain the compression ratio and internal clearances specified for the OM611 power unit.

In internal combustion engines, pistons facilitate the transfer of energy from the expanding gases to the mechanical drivetrain. By moving reciprocally within the cylinder bore, the piston manages the intake, compression, power, and exhaust strokes. Maintaining the integrity of the piston and its associated rings is necessary for the efficient operation of the engine and the prevention of blow-by or oil consumption issues.
