Cylinder head for Citroën XUD9

The cylinder head 9400201120 is a component for the Citroën XUD9 engine. It mounts to the top of the engine block to seal the cylinders and form the combustion chamber where fuel ignition occurs. This component integrates the intake and exhaust ports, valve seats, valve guides, and housings for injectors and glow plugs. It is engineered to manage thermal transfer through the engine cooling system while maintaining the structural requirements of the combustion cycle.

This part is compatible with Citroën XUD9 and Citroën XUD9 LEVAS/WITH engine configurations. It ensures the engine maintains the necessary compression levels for operational performance. The cylinder head is a critical assembly that houses the valvetrain and facilitates the flow of air and fuel into the cylinders while allowing exhaust gases to exit. By providing a precise seal against the engine block, it supports the overall efficiency and pressure management of the diesel engine system.
