一台宝马MPH120型稳定土路拌机配置道依茨BF10L513型柴油机。在路基施工过程中,柴油机油底壳中机油液面不断上升,机油变稀、黏度下降、排气冒白烟。产生上述故障的原因可能有:柴油中有水;喷油提前角太小以及喷油雾化不良等,导致柴油进入油底壳中。由于喷油泵一直没有拆装过,故排除喷油提前角太小的故障。将柴油箱和油水分离器中的水放尽,故障现象依旧。
A BMW MPH120 stable soil mixer configuration DEUTZ BF10L513 diesel engine. In the process of roadbed construction, the oil level in diesel oil pan rises continuously, the oil gets thinner, the viscosity decreases, and the exhaust gas takes white smoke. The reasons for the above failures may include: diesel in water; fuel injection advance angle is too small and poor spray atomization, resulting in diesel into the oil pan. As the fuel injection pump has not been disassembled, it eliminates the fuel injection advance angle is too small fault. The diesel tank and water separator to drain the water, the fault still.
