喷油泵的供油量及其均匀性对发动机的动力性及经济性具有重要影响,在试验台上保证供油量调整的准确性是很重要的。试验台上供油量的准确程度受油嘴开启压力、高压油管长度、输油压力、输油温度等因素的影响。通过试验探讨以上诸因素对供油量的影响规律,在调整供油量时适当控制各影响因素的变化,达到供油量调整准确的要求。 Fuel injection pump fuel supply and uniformity of the engine power and economy have a significant impact on the test rig to ensure the accuracy of the fuel supply adjustment is very important. The accuracy of the test bench oil supply by the nozzle opening pressure, high pressure tubing length, oil pressure, oil temperature and other factors. Through experiments to explore the above factors affecting the law of supply, the amount of oil in the adjustment of the appropriate control of changes in various factors, to meet the precise adjustment of fuel requirements.
