在东风4型机车上装有电动机油泵和燃油泵，在每次起动前需延时45s~60s 供机油和燃油，供机油是为了防止在柴油机停机时间较长时，其各运动部件拉伤，而提供的燃油则是为柴油机点火建立燃油压力。在供机油过程中，起动滑油泵运转时间不能过长，否则不利于蓄电池的保养。在起动过程中，起动电机转动和燃油泵向气缸内供油为同步控制。油压建立以前，起动电机不可以停转。 

       起动柴油机必须解决3 个问题：（1）燃油的供给；（2）运动部件的润滑；（3）蓄电池向起动电机供电，QD 带动柴油机转动。在整个起动过程中，对起动电机和喷油泵供油齿条的控制，都是通过起动接触器（Q C）来实现的。 

       这种控制方法存在如下缺陷： 
       a.操纵人员必须通过主观判断起动完成与否来控制柴油机起动，每次起动都需要耳听发火声，眼睛观察机油压力表的变化； 

       b.向气缸内供油过早，在柴油机低速转动时，喷油器的喷油质量很差，将降低气缸内的温度，拖延点火转速，导致起动能量耗高，排烟量大，甚至爆燃； 

       c. 在柴油机气缸内已经点火后，蓄电池继续向起动电机供电，造成蓄电池的放电量大； 

       d. 如果由于某种原因柴油机不能正常点火，将出现起动接触器烧死的情况，并且蓄电池亏能增大。 

       2 柴油机起动过程的编程设计 
       针对目前柴油机起动过程中的缺陷和不足，可以将其起动过程按时间展开，进行编程控制，采用PCC 实现检测和控制环节。 

       柴油机的起动过程大致可分为4 个阶段，准备、柴油机被驱动转动、点火和建立油压稳定运转。准备阶段主要是预供机油和燃油。东风4型机车采用45s 延时控制燃油泵和机油泵运转。实现起动前预先向管路供油。根据起动过程的不同阶段，结合前面柴油机起动过程中的问题，可逐步解决。
