Diesel engine fuel pump maintenance points

First, the use of good diesel and filter off, to ensure that the diesel engine into the diesel fuel pump highly clean. In general, the diesel engine on the diesel filter requirements than the gasoline engine on the petrol requirements are much higher in the use of the requirements to meet the requirements of the diesel, to strengthen the cleaning and maintenance of diesel filters, timely cleaning or replacement of filter; Operating conditions in a timely manner to clean the diesel fuel tank, the tank completely remove the bottom of the sludge and moisture, diesel oil in any of the impurities will be on the diesel fuel injection pump plunger, valve coupling parts and transmission parts cause serious corrosion or wear. Second, we must always check the diesel fuel pump and governor of the oil and its quality is in line with the requirements. Before starting the diesel engine, check the amount and quality of the oil in the diesel fuel pump (except for the fuel pump that is forced to lubricate) to ensure that the oil quantity is adequate and the quality is good. If the oil is deteriorated due to water or diesel oil Which caused the plunger and the valve out of the early wear, resulting in diesel engine power shortage, starting difficulties, serious caused by plunger and the valve even the corrosion of corrosion. Due to the oil pump leakage, the valve out of the valve work, oil pump tappet and shell wear, seal damage, will make the diesel oil into the oil pool and dilute the oil, it should be based on the quality of oil in a timely manner, The pool for thorough cleaning, the oil sump at the bottom of the sludge and other impurities removed, or use a long time the oil will deteriorate. The number of oil can not be too much or too little, the governor refueling too much, easy to lead to diesel "speed", too little oil will make bad lubrication, should be oil or oil surface screws prevail. In addition, when the diesel engine is not used for a long time, be sure to check the oil in the oil pump oil tank, whether it is water, diesel and other impurities, if you want to immediately replace, or because of prolonged storage, easy to make the plunger, Pieces of rust stuck and scrapped.

Third, to regularly check the adjustment of diesel fuel pump fuel supply advance angle and the cylinder oil supply interval angle. In use, due to the coupling coupling bolts loose, camshaft and roller body parts of the wear and tear reasons, often lead to fuel supply advance angle and the cylinder oil supply interval angle changes, so that the quality of diesel combustion deterioration, diesel engine power , Economic deterioration, while starting difficulties, unstable operation, issued abnormal and overheating and so on. In actual use, the majority of drivers pay attention to the overall fuel supply advance angle of the inspection adjustment, but ignored the fuel interval angle (involving a single pump feed advance adjustment) check adjustment, resulting in the overall adjustment, although the first cylinder oil supply , But the rest of the cylinder due to the camshaft, wheel drive parts wear and other reasons so that oil is not necessarily positive, the same will lead to diesel engine start difficult, lack of power, running is not smooth, especially for the use of a longer time for diesel , But also to pay attention to the fuel pump fuel supply interval check the adjustment. Fourth, to regularly check the diesel fuel pump pump to adjust the fuel supply. As the plunger and the valve even wear the valve, resulting in diesel internal leakage, the cylinder will reduce the amount of oil supply or uneven, resulting in diesel engine starting difficulties, lack of power, fuel consumption increased, unstable operation. Therefore, to regularly check the diesel fuel pump to adjust the fuel supply to ensure that the diesel engine power to play. In actual use, you can observe the diesel engine exhaust, listen to the diesel engine sound, touch the exhaust manifold temperature and other methods to determine the size of the cylinder fuel supply.
