Cylinder head for Citroën XUD9

The cylinder head 908020K is a component for the Citroën XUD9 engine, positioned at 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, and valve guides, while also providing mounting points for fuel injectors and glow plugs. It features internal passages for coolant circulation to manage thermal loads and channels for lubricating oil distribution.

This part is compatible with the Citroën XUD9 engine. It maintains the necessary compression levels within the engine cylinders when installed with a matching head gasket. The component ensures the separation of combustion gases from the cooling and lubrication systems, preventing leaks and maintaining engine pressure.

A cylinder head functions as the upper closure for the engine block, creating the space where fuel and air are compressed and ignited. It facilitates the flow of intake air and exhaust gases through the valve ports and manages heat transfer from the combustion process to the engine cooling system.
