Diesel Generator Tech

There is no doubt that fuel injection nozzle burning will definitely influence the normal operation of generator set . If you find the related causes, you can quickly solve the problems. 1. Long time idling operation Due to the diesel engine keeps running slowly for a long time, the temperature in the cylinder is low, the fuel combustion is not sufficient, the combustion chamber and fuel injection nozzle are easy to form carbon deposition. So it leads to the deterioration of working conditions for fuel injection nozzle. Especially in winter, it is even more serious under the condition of cold climate. Because the combustion chamber has carbon deposition, heat dissipation is slow, which may cause spray orifice obstruction of the fuel injection nozzle and the oil drip phenomenon  may happen. The fuel stays in the nozzle head for a long time, the local high temperature will make the nozzle and thermal insulation jacket burned. 2. The fuel is not clean Due to there a...

Fuel injector faults may be caused by the following causes. A little or no fuel injected. Causes: (1) There is air in the fuel supply system. (2) Seizure of the fuel injector nozzle. (3) Abnormal fuel supply from the fuel injection pump. (4) Oil leak at high-pressure fuel pipes. (5) Wear of fuel injector nozzles. Correction Prime the fuel system. Let a professional serviceman check and replace the nozzle assembly. Refer to fuel injection pump fault for troubleshooting. Tighten the pipe locknut and replace the pipes with crack, make replacement if required. Let a professional serviceman replace the nozzle assembly. Too low fuel injection pressure. Causes: (1) Lose pressure regulating screw. (2) Deformation or break of the pressure regulating spring. (3) Seizure of needle valves. Correction: Let a professional serviceman readjust the screw to the defined pressure and tighten the locknut. Let a professional serviceman replace the injector ...
