喷油泵是柴油机上最重要的部件之一,它调整得好坏直接影响到柴油机的性能。因此,喷油泵的调整和安装必须按照规定进行,才能使喷油泵与柴油机达到最佳的匹配。罗马尼亚进口的DAC6135货车,装有DPA型分配式喷油泵(见图1)。该泵装有机械离心式全程调速器;带有键槽的斜齿轮传动;具有液压自动提前装置,以顺时针方向转动;柱塞直径为 Fuel injection pump is one of the most important components of diesel engine, it adjusts the quality of a direct impact on the performance of the diesel engine. Therefore, the fuel pump adjustment and installation must be carried out in accordance with the provisions of the injection pump and diesel engine to achieve the best match. The DAC6135 truck imported from Romania is equipped with a DPA type injection pump (see Figure 1). The pump is equipped with a mechanical centrifugal full speed governor; helical gear transmission with keyway; with hydraulic automatic advance device to rotate clockwise; plunger diameter
