What is a common rail system？
The common rail system refers to a closed-loop fuel supply system composed of a fuel tank, a gear pump, an oil-water separator, a gear pump, a diesel fine filter, a high-pressure pump, a common rail pipe, an injector, and sensors and an ECU. It completely separates the generation of injection pressure and the injection process.
Working principle of common rail system
The common rail system is currently the most widely used fuel supply system in diesel engines. Its working principle is to pass fuel through a high-pressure pump, raising the fuel pressure to a very high level, and then sending the fuel into a pipeline called the common rail. In this pipeline, the pressure of the fuel is maintained at a relatively constant level, which ensures that the flow rate and pressure of the fuel are stable during injection from the fuel injector, thereby achieving better combustion efficiency.
