Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine disassembly equipment, in particular to a diesel engine injector disassembly tool. Background Art

[0002] The fuel injector is a key component of a diesel engine. It atomizes the diesel fuel and sprays it into the engine's combustion chamber, allowing the fuel to mix thoroughly with air. This converts the heat generated by the fuel combustion into mechanical energy that drives the load. According to research on shipping vessels, as the main engine is used, the injectors are regularly maintained and tested, and when an injector malfunctions, the injectors need to be removed. However, removing the injectors is extremely difficult. Improper installation often creates a gap between the injector and the cylinder head. When the injector operates for long periods of time and is exposed to high temperatures, the injector and cylinder head can become stuck, making the injector extremely difficult to remove. Conventional methods and tools are typically used to remove the injectors, but this is difficult, labor-intensive, and inefficient, potentially stranding the vessel at port. Forced removal can also damage the injectors, cylinder heads, and accessory components, resulting in unnecessary economic losses. Utility Model Content
