Diesel engine electronically controlled high-pressure common rail fuel injection technology integrates computer control technology, modern sensing detection technology and advanced injector structure. It can not only achieve higher injection pressure, realize control of injection pressure and fuel injection volume, but also realize pre-injection and segmented injection, thereby optimizing fuel injection characteristics, reducing diesel engine noise and improving emission standards. It is suitable for meeting National III and above standards. One of the main fuel injection systems for emission standards. Its characteristics are as follows.

1. The use of advanced electronic control devices and high-speed solenoid valves (on the fuel injectors) (as shown in the figure) makes the control of the fuel injection process very convenient and has many controllable parameters, which is conducive to the optimization of the entire diesel engine combustion process. .
2. Using common rail fuel injection, the pressure fluctuation of the entire fuel injection system is small, the mutual influence between the injectors of each cylinder is small, the injection pressure control accuracy is high, and the fuel injection volume control is more accurate.
3. The high-speed solenoid valve has high frequency and flexible control, which makes the injection pressure of the diesel engine injection system have a wide adjustable range, and can easily realize pre-injection and other functions. It provides a solution for optimizing the diesel engine injection regularity, improving its performance and reducing exhaust emissions. effective means.
4. The entire fuel system structure is easy to transplant and has a wide range of adaptability, especially it can be well matched with current small, medium and heavy-duty diesel engines, so the market prospect is broad.

5. The injection timing can be independently and flexibly controlled, and combined with high injection pressure (120-200mpa), the commonly used common rail fuel system of Bosch Company has a common rail pressure of 145MPa, which can simultaneously control NOx and particulate matter (PM). within a smaller value to meet emission requirements.
