Introduce high pressure common rail injection system

It uses a fuel pump to transport high-pressure oil to a common, large-volume oil distribution pipe and oil rail, accumulates the high-pressure oil, and then transports it to the injector through the high-pressure oil pipe, that is, multiple injectors are connected in parallel on the common oil rail. On the common oil rail, an oil pressure sensor, pressure limiting valve and flow limiter are installed. Since the microcomputer accurately controls the fuel pressure in the fuel rail, the fluctuation of the fuel supply pressure in the fuel system caused by changes in the diesel engine speed is significantly reduced (this is a major flaw of the traditional diesel engine). The amount of fuel injection only depends on the opening time of the injector solenoid valve.
Features:
1.Completely separate the generation of fuel pressure from the injection process. The establishment of fuel pressure has nothing to do with the injection process. After the fuel is sprayed from the injector, the oil pressure in the fuel rail is almost unchanged;
2.The fuel pressure, injection process and injection duration are controlled by a microcomputer and are not affected by the diesel engine load and speed;
3.Injection timing and injection metering are controlled separately, and the injection amount and injection starting angle of each cylinder can be freely adjusted.
