30kw Large Diesel Generator
The diesel engine is running at normal speed under the drive of the starter, but it fails to start and there is no explosion sound. No diesel smell or smoke is emitted from the exhaust pipe outlet, indicating that diesel has not entered the cylinder. Possible causes for this situation include:
1The fuel tank is empty, the fuel tank switch is not turned on, or the ignition pull lever has not been returned.
2Injection pump fuel lever stuck, air in the oil line, clogged filters, and twisted, bent hoses in the oil line.
3The filter screen at the oil inlet of the fuel pump is clogged, there is water in the oil line causing freezing in winter, and the incorrect diesel grade is being used. If summer oil is used during winter, the diesel will condense and separate into paraffin, thereby blocking the oil line.
4Injector pintle stuck, not spraying fuel; damage to the injection pump drive gear; and damage to the injection pump camshaft keyway or semi-circular key.

Causes of Oil Leaks in Diesel Generator High-Pressure Fuel Lines: Oil leaks typically occur due to cracks or fractures at the pipe joint, usually resulting from loose seals at the connection points of the high-pressure fuel line, injectors, and fuel pumps. After inspecting and eliminating oil leakage issues from the injectors and fuel pumps, check if the cold-forged conical surfaces of the finished high-pressure fuel lines meet the drawing specifications and if there are any dimensional errors in the bends. The vibration of the high-pressure fuel line, combined with bending errors and resulting installation stress, can exacerbate loose seal conditions on the conical surfaces. To ensure the precision of the seal cone shape and dimensions, it is recommended to add a process of precision grinding the conical surface before cold-forging the connection head of the high-pressure fuel line and before bending the pipe. This ensures the accuracy of the conical surface dimensions and shape, usually requiring grinding for each high-pressure fuel line.0.02—0.05mmTo form a complete and good conical surface, some parts require grinding.1.0mmAbove. Additionally, after cold heading, the parts should be stored with protective covers to completely eliminate the issue of part damage.VITwo-cylinder high-pressure fuel lines are more prone to breakage compared to other cylinders. In addition to the quality of the fuel lines themselves, the primary cause is often the failure to properly install or position the high-pressure fuel line clamp during maintenance and the disassembly and reassembly of the fuel injection pump.
