高压共轨发动机原理
高压共轨又称电喷柴油机，而采用电子控制燃油喷射及排放的柴油机即为电喷柴油机。电喷柴油发动机的喷射系统由传感器、ECU(计算机)和执行机构三部分组成。其任务是对喷油系统进行电子控制，实现对喷油量以及喷油定时随运行工况的实时控制。采用转速、油门踏板位置、喷油时刻、进气温度、进气压力、燃油温度、冷却水温度等传感器，将实时检测的参数同时输入计算机(ECU)，与已储存的设定参数值或参数图谱(MAP图)进行比较，经过处理计算按照*佳值或计算后的目标值把指令送到执行器。执行器根据ECU指令控制喷油量(供油齿条位置或电磁阀关闭持续时间)和喷油正时(正时控制阀开闭或电磁阀关闭始点)，同时对废气再循环阀、预热塞等执行机构进行控制，使柴油机运行状态达到*佳。
