1.直列泵系统体积较大,每个气缸对应一个分泵,分泵与对应缸之间通过高压油管连接,喷油器利用柴油自身的压力被动喷油。该系统多采用机械离心式调速器,可靠性较好,但精度较差。驾驶员通过油门控制调速器弹簧的预紧力,飞锤离心块产生的离心力与弹簧力相互制约,保持动态平衡。弹簧力将油量控制机构向供油量增加的方向移动,供油量增加使柴油机加速,同时调速器飞锤离心块的离心力也增加,离心力使油量控制机构向减油的方向移动,制约转速的增加,油门位置与调速弹簧预紧力对应,弹簧预紧力与转速相对应,从
1. Inline pump system larger, each cylinder corresponds to a sub-pump, sub-pump and the corresponding cylinder through the connection between the high-pressure tubing, injector using diesel pressure on their own passive fuel injection. The system uses mechanical centrifugal governor, reliability is better, but the accuracy is poor. The driver controls the pre-tightening force of the governor spring through the throttle and the centrifugal force and the spring force generated by the centrifugal hammer of the flying hammer restrict each other to maintain the dynamic balance. Spring force to the fuel control mechanism to increase the direction of the amount of fuel to increase fuel supply to accelerate the diesel engine, centrifugal governor flyweight centrifugal block also increased centrifugal force to the oil control mechanism to the direction of reducing oil, Restricting the increase of rotational speed, the accelerator position corresponds to the pre-tightening force of the governor spring, and the pre-tightening force of the spring corresponds to the rotational speed.
