典型的燃油系统示意图

燃油供油油路是一种传统设计,用于使用喷油器的发动机。 供油油路使用输油泵将燃油从油箱输送到电子喷油器。 输油泵是一种定量泵。

燃油继而流经燃油滤清器,然后进入供油歧管。 用于加注系统的燃油燃油充油泵位于燃油滤清器底座上。 更换滤清器后必须充注系统。 排放供油和回油歧管,更换喷油器之后,必须充注系统。

燃油连续不断地自供油歧管流经喷油器。 燃油会在喷油器的供油口或注油口没有被喷油器体组件柱塞关闭时流过喷油器。 没有喷入气缸的燃油经过回油歧管流回油箱。

回油歧管的端部有一个压力调节阀。 压力调节阀控制整个燃油系统的压力。 该调节使得喷油器能够被正确加注。

电子控制机械驱动的喷油器系统提供了喷射正时的全面电子控制。 改变喷油正时是为了优化发动机的性能。

正时环是后齿轮总成的一部分。 发动机转速 / 正时传感器产生一个信号。 此信息用于检测曲轴位置和发动机转速。 其他信息和这些数据允许电子控制模块(ECM)向喷油器电磁阀发送信号。 喷油器电磁阀通电激励以便开始喷油。 喷油器电磁阀断电以便结束喷油。 请参阅系统操作, "喷油器"。
