Description
What does an injector sleeve do?
This cylinder head injector sleeve acts as a critical housing tube within the cylinder head, separating the injector from the engine's coolant passages. By maintaining a precise seal between the combustion chamber and the water jacket, it prevents coolant ingress into the fuel system. It also functions as a thermal bridge, conducting heat from the injector to the coolant to manage operating temperatures during heavy-duty cycles.Compatible vehicles and engines
This component is compatible with Scania engines used in heavy commercial vehicles. It is designed to maintain the injector at a fixed depth and correct axis, ensuring optimal combustion and fuel injection performance. The sleeve is manufactured from high-strength components to withstand continuous thermal expansion and contact with engine coolant.Installation and maintenance
When performing injector maintenance or cylinder head servicing, technicians should inspect the sleeve for signs of wear or corrosion. It is often replaced alongside sealing gaskets to ensure a complete and reliable seal. Proper installation is vital to prevent vibrations or leakage within the combustion chamber.Troubleshooting and selection
