Cylinder head for Mercedes-Benz OM

The cylinder head, part number A6510108418, mounts to the top of the engine block to seal the cylinders and form the combustion chambers. This component houses the intake and exhaust valves, valve seats, valve guides, and fuel injectors for the Mercedes-Benz OM651 engine. It contains internal passages for the circulation of coolant to manage thermal loads and oil galleries to provide lubrication to the valve train mechanism.

This component is compatible with the Mercedes-Benz OM and OM651 engine series. It is engineered to maintain the structural integrity required to contain the combustion pressures and temperatures generated during operation. The cylinder head is essential for maintaining proper engine compression, which directly influences power output, fuel efficiency, and emissions compliance.

In an internal combustion engine, the cylinder head acts as the primary interface for gas exchange. By housing the valve train and providing the necessary geometry for the combustion process, it ensures that air and fuel are delivered and exhaust gases are expelled according to the engine timing. Proper sealing between the cylinder head and the engine block is necessary to prevent fluid cross-contamination and loss of cylinder pressure.
