新买的或刚修理过的柴油机,特别是更换或修理过机油泵的柴油机,在起动之前,可用摇车法检查润滑系统的工作情况是否正常,其方法如下: 1.关闭油门,打开减压手柄,使发动机处于减压状态。 2.用摇把转动曲轴,观察机油指示器内的指针是否升起,若指针升起,说明润滑系统工作正常;若指针不升起,则表明润滑系统有问题。 Newly purchased or newly repaired diesel engines, particularly diesel engines that have been replaced or repaired with an oil pump, can be checked for operating conditions of the lubrication system by the crank method before starting, as follows: 1. Shut off the throttle and open the depressurized Handle, the engine in a decompression state. 2. Turn the crankshaft with the crank and observe if the pointer in the oil indicator rises. If the pointer rises, it indicates that the lubrication system is working normally. If the pointer does not rise, it indicates that there is a problem with the lubrication system.
