Piston for Mercedes-Benz OM364

The piston 87-740000-40 functions within the combustion chamber of the Mercedes-Benz OM364 engine. It receives the force generated by the combustion process and transmits this energy through the connecting rod to the crankshaft, which facilitates the rotation of the engine assembly. The component features integrated grooves designed to accommodate piston rings, which manage compression, regulate oil consumption, and assist in thermal transfer between the piston and the cylinder wall.

This component is compatible with the Mercedes-Benz OM364 engine series. The actual manufacturer of this part is Mercedes-Benz. The dimensions and surface finish are engineered to meet the original specifications required for proper clearance and sealing within the cylinder liner.

In internal combustion engines, the piston acts as a movable plug that seals the cylinder volume. It must withstand the pressure and temperature cycles inherent in engine operation while maintaining a sliding fit against the cylinder bore to ensure efficient power conversion.
