How to Check The Quality of Diesel Generator Set Fuel Injection Pump

Sep. 11, 2021

Do you know how to check the quality of the fuel injection pump of a diesel generator set? Use and filter the diesel fuel to ensure that the diesel fuel entering the fuel injection pump is highly clean. Generally speaking, the filtration requirements of diesel generator sets for diesel are much higher than those of gasoline engines. When using diesel generators, it is necessary to select diesel that meets the required grades, and at least 48 hours of precipitation. Strengthen the cleaning and maintenance of the diesel filter, clean or replace the filter element in time; clean the diesel tank in time according to the operating environmental conditions to remove the sludge and moisture at the bottom of the fuel tank. Any impurities in the diesel fuel will affect the plunger of the fuel injection pump and the fuel delivery valve. The mating parts and transmission parts cause severe corrosion or wear.

Secondly, always check whether the amount and quality of the oil in the oil pool of the fuel injection pump meet the requirements. Before starting the diesel generator set, check the quantity and quality of the oil in the fuel injection pump (except for the fuel injection pump that is forced to be lubricated by the engine) to ensure that the quantity of oil is sufficient and the quality is good. This will cause early wear of the plunger and delivery valve assembly, resulting in insufficient power of the diesel engine, difficulty in starting, and in severe cases, corrosion of the plunger and delivery valve assembly.


Due to internal leakage of the oil pump, poor operation of the oil outlet valve, wear of the oil delivery pump tappet and casing, and damage to the sealing ring, diesel will leak into the oil pool and dilute the oil. Therefore, the oil should be replaced in time according to the quality of the oil. Clean the tank to remove the sludge and other impurities at the bottom of the oil tank, otherwise the engine oil will deteriorate if it is not used for a long time. The amount of oil should not be too much or too little. Too much oil in the governor will easily cause the diesel engine to "runaway". Too little oil will cause poor lubrication. The oil dipstick or the oil flat screw shall prevail. In addition, when the diesel engine is not used for a long time, be sure to check whether there are impurities such as water, diesel, etc. in the oil sump of the oil pump, and replace it immediately. Otherwise, due to long-term storage, the water will easily cause the plunger and the oil outlet valve to be coupled. Corrosion stuck and scrapped.
