Cylinder head for Citroën XUD9

The cylinder head, part number 908731K, seals the top of the cylinders in the Citroën XUD9 diesel engine to form the combustion chamber. This component houses the intake and exhaust valves, fuel injectors, and preheating plugs necessary for the engine combustion cycle. Maintaining a flat surface and a proper seal is required to preserve engine compression and prevent the leakage of combustion gases or coolant into the engine block.

This component is compatible with the Citroën XUD9 and Citroën XUD9 LEVAS/WITH engine models. It is engineered to meet the specific dimensional and functional requirements of these power units to ensure correct fitment and operation within the engine assembly.

A cylinder head functions as the upper closure of the engine block, providing the structural housing for the valve train and the ports for air intake and exhaust gas discharge. By securing the combustion space, it allows the engine to convert fuel energy into mechanical work while managing the thermal and pressure loads generated during operation.
