在试验分析的基础上查找了4PY340W喷油泵配QC4115T柴油机冷启动困难的原因。通过增加启动弹簧刚度和减小负校正量,有效地改善了柴油机的启动性能,使问题得以圆满解决。
Based on the experimental analysis, we find the reason why 4PY340W injection pump is equipped with QC4115T diesel engine. By increasing the starting spring stiffness and reducing the amount of negative correction, effectively improve the starting performance of the diesel engine so that the problem can be satisfactorily solved.
