柴油发动机喷油泵.供油提前角过早或过晚都会使发动机功率下降,耗油量上升,造成发动机起动困难,甚至不能起动。鉴别供油提前角过早过晚的方法如下: 1.看发动机排烟。供油提前角过早或过晚,都容易引起发动机排烟。过早多排黑烟,过晚多排白烟,如发动机温度越低,转速越高,负荷越小,排白烟现象就越严重,同时排气管子有啪啦声. 2.听发动机敲击声。供油提前角
Diesel engine fuel pump. Early or too late fuel supply will make the engine power down, fuel consumption increases, causing the engine start difficult, or even can not start. Identification of fuel advance too early too late as follows: 1. Look at the engine exhaust. Fuel advance too early or too late, are likely to cause engine exhaust. Too many rows of black smoke too early, too late row of white smoke, such as the lower the engine temperature, the higher the speed, the smaller the load, the more serious row of white smoke, while the exhaust pipe has a crackling sound. Strike sound. Fuel advance angle
