Description
What does an injector sleeve do?
This cylinder head injector sleeve acts as a critical dry housing tube within the engine's combustion chamber. Its primary role is to separate the fuel injector from the coolant passages while maintaining the injector on its correct axis. By conducting heat from the injector to the coolant, it also functions as a vital thermal bridge to prevent overheating during high-load operations.Engine compatibility and fitment
This component is specifically engineered for a wide range of Volvo engines, including those found in Volvo F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 models. It is compatible with various engine families such as TD70, TD100, TD101, TD102, TD103, D10A, TD120, TD121, TD122, and D12A.Installation and maintenance guidance
When performing engine maintenance or injector servicing, technicians should inspect the sleeve for signs of thermal fatigue or erosion. Proper installation is essential to ensure the seal between the combustion chamber and the water jacket remains intact under high pressure. It is recommended to assess the condition of sealing elements during any injector removal or cylinder head service.Service recommendations
Maintaining precise injector seating helps prevent leaks and ensures optimal combustion efficiency in heavy-duty diesel engines. Consult your authorized distributor.OE cross-reference
