本文阐述了柴油发动机在动态、空载工况下,采用“断缸──闭气”法或“断缸──调油”法以获取额定转速,以便测验喷油泵的额定转速和额定转速时的油量。并阐述了“YB-1型喷油泵电子测试仪”和“电子自控量油装置”的功用与操作方法。以及对该仪器的可靠性和精确度所做的对比试验。作者认为采用该仪器系统和相应的测验方法,可作为柴油机喷油泵随车检查的手段,必要时还能随车调试喷油泵的额定油量、各缸匀性、发动机的额定转速和最高空转转速。 This article describes the diesel engine in the dynamic, no-load conditions, the use of “broken cylinder ─ ─ closed air” or “broken cylinder ─ ─ oil transfer” method to obtain the rated speed, in order to test the rated speed of the injection pump and rated speed Oil volume. And expounds the function and operation method of “YB-1 fuel injector electronic tester” and “electronic self-control oil device”. As well as a comparative test of the reliability and accuracy of the instrument. The authors believe that the instrument system and the corresponding test methods can be used as a means of diesel fuel injection truck on-board inspection, if necessary, can also test the fuel pump rated fuel, cylinder uniformity, engine rated speed and maximum idle speed .
