Fuel rail assembly 1100100-EG01 for Great Wall engine Haval H6
The fuel rail consists of the following components:
1. Fuel Inlet: The fuel inlet channel that connects to the high-pressure fuel pump
2. Seat Assembly: Multiple connectors that connect directly to the injectors
3. Pressure Regulator (optional): Some fuel rails have a pressure regulator installed at one end.
Description
油轨总成是共轨燃油供给系统的核心部件，承担着以下主要功能：
燃油储存与压力调节
油轨总成是共轨系统的标志性部件，它用于储存高压燃油并抑制压力波动，其物理结构能够有效缓冲高压泵和喷油器产生的压力脉动，保证各缸燃油压力均匀一致，避免因压力不均而导致的喷射量波动。
均匀燃油分配
轨总成采用内部流道设计，确保燃油均匀输送至各缸喷油器。例如，在奥迪等系统中，低压轨会先对燃油加压，然后再将其送入高压轨。压力传感器实时监测压力，并与ECU协调，实现精准的燃油输送。
