Piston for Mercedes-Benz OM364

The piston 87-117900-00 is a core component within the Mercedes-Benz OM364 diesel engine. It functions by converting the energy generated from the combustion process into linear motion, which is subsequently transferred to the crankshaft to create rotational movement. This component is engineered to manage the pressures and temperatures present within the combustion chamber during each engine cycle.

This part is compatible with the Mercedes-Benz OM364 engine. It includes specific grooves machined for the installation of compression and oil control rings, which are necessary for maintaining proper compression and managing lubricant levels within the cylinder bore.

In internal combustion engines, the piston acts as a movable barrier that seals the combustion chamber. By moving within the cylinder liner, it facilitates the intake, compression, power, and exhaust strokes. Proper fitment and surface finish are required to ensure the piston moves with minimal friction while maintaining a tight seal against the cylinder wall to prevent gas leakage and oil consumption.
