我公司几台小松WA500-6型装载机作业过程中,常出现突然降速、熄火现象,再次启动作业一段时间后又出现熄火,且故障发生越来越频繁。现对该装载机燃油供给系统原理及常见故障排查方法分述如下。1.燃油供给系统原理日本小松WA500-6型装载机采用SAA6D140E-5型柴油机。该型柴油机燃油供给系统采用日本电装公司的ECD-U2型高压共轨电控燃油喷射系统,简称CRI系统。该系统可对柴油机的喷油定时、喷油持续期、喷油压力、喷
My company several Komatsu WA500-6 loader operation process, often sudden sudden deceleration, flameout phenomenon, start the operation again after a period of time there flame out, and the failure occurs more frequently. Now the principle of the loader fuel supply system and common troubleshooting methods are as follows. 1. Fuel Supply System Principle Japan’s Komatsu WA500-6 Loader SAA6D140E-5 type diesel engine. This type of diesel fuel supply system uses the Denso Corporation ECD-U2 high-pressure common rail electric fuel injection system, referred to as the CRI system. The system can diesel injection timing, injection duration, injection pressure, spray
