一丰收-35型拖拉机在行驶途中突然熄火,再次起动,工作如常,音度、烟色亦无异常现象,中速行驶状况良好,只是中速加大油门后速放油门时,发动机才熄火。这种征象表明,故障出在燃油供给系。疑是喷油泵油量控制阀涩滞所致,遂打开喷油泵顶盖。拿出油量控制阀一看,其上甚多油污,且阀体不能灵活转动,由于油量控制阀涩滞,当油门增大后速放油门时,油量控制阀不能迅速回位,以增大供油量,而仍处在减少供油量位置,使供油不足,从而导致发动
A harvest -35 tractor in the middle of a sudden turn off, start again, work as usual, the tone, smoke color is no exception, good speed in the medium-speed driving, but only in the throttle after the accelerator pedal speed, the engine stalls. This sign shows that the fault lies in the fuel supply system. Suspected injection pump fuel control valve due to stagnation, then open the fuel injection pump roof. Out of the oil control valve to see a lot of oil on it, and the body can not be flexible rotation, as the fuel control valve stagnation, when the throttle increases after the release of the throttle, the fuel control valve can not be quickly returned to Increase the amount of oil supply, while still in the position of reducing fuel supply, making oil shortage, which led to the mobilization
