对柴油机配气实行电子控制的必要性进行了阐述。介绍了 1 3 5型柴油机所设计的一套电子控制液压驱动的可变气门系统。包括液压系统的选择 ,气门驱动机构的设计及其有关参数的确定 ,以及电子控制单元的硬件设计等 ,并给出了初步实验结果。试验证明 ,针对 1 3 5型柴油机所设计的电控可变气门系统基本能够满足设计的初步要求 ,在 1 5 0 0 r/min时 ,2 70℃ A内能完成气门的开启与关闭动作 ,并且其时面值可以调节 ,基本上能满足其他非标定转速 ,尤其是低转速工况下对气门正时进行调节的需要
The necessity of implementing electronic control of diesel engine gas distribution is described. A set of electronically controlled hydraulically driven variable valve system designed by a 1 35 diesel engine is introduced. Including the selection of hydraulic system, the design of valve drive mechanism and its related parameters, as well as the hardware design of electronic control unit, and gives the preliminary experimental results. The test proves that the electronically controlled variable valve system designed for a 1 35 diesel engine can basically meet the preliminary design requirements, and the valve opening and closing operations can be completed within 2 70 ° C at 1 5 0 0 r / min, And its face value can be adjusted, basically to meet other non-calibrated speed, especially in low speed conditions to adjust the valve timing needs
