Abstract
Engine fuel system of articulated truck of Komatsu HM400-2 model is using the high pressure common rail technology. Its adaptability to poor quality fuel causes frequent faults to high pressure common rail tank. This kind of fault restricts the equipment utilization rate becomes one of the key factors to decrease the equipment failure rate. In this article, the high pressure common rail technology is introduced, the common rail tank failure phenomena is described and analyzed, combining the characteristics of the articulated truck engine fuel system structure. Based on the same model engine fuel filter structure of successful experience, the retrofit scheme of fuel oil filter system is put forward, and implemented, which has obtained the good effect.关键词
