柴油机在工作过程中,由于使用不当或部件故障,转速会逐渐降低或突然降低而自行熄火。根据熄火时转速降低速度和所排烟色,可判断其故障原因。 1.熄火时,柴油机转速逐渐降低,柴油机响声和烟色无异常变化 此故障多发生在燃油系,一般要检查燃油是否用完,或油箱通气孔是否堵塞形成真空。如无上述问题,再由低压至高压检查油路,看油路是否堵塞,油路中是否有空气;高压油路中可 Diesel engine in the course of their work, due to improper use or parts failure, the speed will gradually reduce or suddenly reduce the self-extinguishing. According to the speed of flameout to reduce the speed and smoke color, you can determine the cause of the malfunction. 1. Turn off the engine, diesel engine speed gradually decreased, diesel engine noise and no abnormal changes in smoke This failure occurred in the fuel system, the general should check whether the fuel is exhausted, or the fuel tank vent is blocked to form a vacuum. If none of the above problems, and then by the low pressure to high pressure check the oil circuit to see if the oil circuit is blocked, whether there is air in the oil circuit;
