提出了一种微机控制的柴油机燃油喷射系统,设计了系统的硬件和软件,并在油泵试验台上对系统进行了性能试验。由试验可知,完成一次喷油动作的最小时间为0.9ms;喷油量的可控范围可达50°;喷油正时的可控范围可达±30°油泵轴转角;喷油正时及喷油量的控制误差均小于0.36°CA。
A microcomputer-controlled diesel fuel injection system is proposed. The hardware and software of the system are designed. The performance of the system is tested on the oil pump test bench. It can be seen from the test that the minimum time to complete an injection action is 0.9 ms; the controllable range of the fuel injection amount can reach 50 °; the controllable range of the injection timing can be up to ± 30 °; the rotation angle of the pump shaft; And the control error of fuel injection quantity is less than 0.36 ° CA.
