1柴油机供给系统的主要测试项目柴油机由于使用的燃料及燃料供给系统与汽油机不同,故在检测内容、方法上和汽油机相比有许多不同之处。在发动机不解体情况下,如利用QFC-5型发动机综合测试仪检测柴油机的综合参数,该仪器显示器能以多种形式观测各缸高压油管中的压力波和喷油器针阀升程波形,能定量、准确地测出喷油器的针阀开启压力 1 diesel engine supply system of the main test items Diesel fuel and fuel supply system used and gasoline engine different, so in the test content, methods and gasoline engine compared to many differences. In the case of the engine does not disintegrate, such as the use of QFC-5 engine tester to test the comprehensive parameters of the diesel engine, the instrument can monitor the various forms of high pressure tubing in each cylinder pressure wave and injector needle valve lift waveform, Can quantitatively and accurately measure the needle valve opening pressure of the injector
