车用大功率柴油机转速闭环控制方案的研究

【摘要】 在柴油机电控喷油系统的基础上研究了转速闭环控制，通过控制喷油泵的供油齿杆位置，达到控制喷油量的目的。相对于实际油门位置提出并应用了当量油门位置的概念。试验结果表明：车用大功率柴油机转速闭环控制方案是可行的，控制效果较好，对车辆动力与传动系的综合电控研究具有重要的意义。更多还原

【Abstract】 Investigation work of closed cycle control scheme of engine turning speed is made in diesel engine electronically controlled fuel injection system by means of controlling the position of fuel feeding toothed rod to fulfill the aim of fuel injection amount control.In the course of closed cycle control scheme, concept of equivalent fuel feeding actuator position is proposed and applied corresponding to the actual fuel feeding actuator position.The investigation of closed cycle control system of large power diesel engine turning speed on motor vehicle is feasible and fairly good,which has an important significane for synthetic eletronical control research work of motor vehicle power and transmission system.更多还原
