Description
The cylinder head injector sleeve serves as a critical dry housing tube within the engine, separating the fuel injector from the coolant passages. By maintaining the injector at a fixed depth and correct axis, it ensures a consistent seal between the combustion chamber and the water jacket while acting as a thermal bridge to conduct heat away from the injector.
This component is specifically engineered for Scania engines, providing reliable performance under heavy-duty operating conditions. It is essential for maintaining combustion chamber integrity and preventing coolant contamination into the fuel system.
During installation, technicians should ensure the cylinder head bore is clean and inspect the seating surface. Proper seating is vital to prevent vibration or leakage. It is recommended to replace the sleeve alongside any associated sealing elements during injector service to ensure optimal system pressure and thermal transfer.
Check the compatibility list to confirm exact fitment for your specific engine configuration.
