Research on the Cause of Imperfect Ignition or Rough Running of the CAT938 Loader and its Solution

针对卡特彼勒CAT938F装载机发动机点火不良或运转不平稳的情况,找出其故障点且加以排除.由于CAT938采用了单体泵的设计,在车辆运行中经常出现某一缸的喷油器出现故障.在此主要就喷油器的故障加以分析、判断和解决,减少维修时间,使机械在安全、可靠的状态下工作.

In view of the condition of imperfect ignition or rough running of the Caterpillar CAT938F loader engine,the faulty position has been located and eliminated.Since single pump is designed in the CAT938F loader,the injector of a cylinder often breaks when the vehicle is running.This paper mainly analyze,judge and solve the fault of the injector in order to reduce the maintenance time so that the machinery is in a safe,reliable operating mode.
