Description
What does an injector sleeve do?
This cylinder head injector sleeve functions as a critical dry housing tube within the engine cylinder head. By separating the injector from the coolant passages, it prevents direct contact between the injector and the water jacket while maintaining a secure seal between the combustion chamber and the cooling system. It also acts as a vital thermal bridge, conducting heat away from the injector to ensure optimal engine performance.Compatibility and engine fitment
This component is specifically designed for use in Mercedes-Benz heavy commercial vehicle engines. It provides the necessary structural support to keep the injector at a fixed depth and on its correct axis during high-pressure combustion cycles. Proper fitment ensures the integrity of the sealing arrangement within the cylinder head assembly.Maintenance and installation guidance
For professional workshop technicians, it is recommended to inspect the sleeve and its sealing elements during any injector or cylinder head maintenance. Maintaining a precise seal is essential to prevent coolant ingress into the combustion chamber or loss of compression. Check the compatibility list to ensure correct application for your specific engine model.OE cross-reference
