有一部黄河牌汽车(其上安装的是6135型柴油机),大修后起动困难。蓄电池正常,起动机转速正常,供油时间也准确,喷油泵供油也正常,低压油路无空气,喷油器喷油压力、雾化正常。但起动困难,且发动机冒烟,发动机温度提高后,发动机冒烟大为减轻,汽车行驶动力正常。 根据上述情况,对配气机构做了细致检查,配气相位正确,进、排气门密封良好,气门下陷度符合规定。显然配气机构没有问题,由 There is a Yellow River car (which is installed on the 6135-type diesel engine), overhaul difficult start. Battery is normal, starter speed is normal, the fuel supply time is accurate, fuel injection pump is also normal, low-pressure oil air, injector fuel injection pressure, normal atomization. But difficult to start, and the engine smoke, the engine temperature increases, the engine smoke greatly reduced, the driving power of the car is normal.
