2. Admitting high-pressure common rail method for oil supply, the pressure of the fuel injection system is small, the mutual influence between the injectors is small, the pressure size is independent of the engine speed, the injection pressure control accuracy is high, the injection quantity control is correct, and the pressure is high. The fuel injection pressure in the common rail system is flexible, and the optimum injection pressure can be determined for differential operating conditions to optimize the comprehensiveness of the diesel fuel.
3.Adoption of electronically controlled high pressure common rail technology comprehensively optimizes the injection discipline of the diesel engine (close to aspiration, easy to achieve pre-injection and multi-injection, can independently control the injection timing flexibly, with full high injection pressure, can be controlled The smaller values ​​of nitrogen oxides and particulates meet the requirements for satisfactory emissions, while at the same time ensuring excellent dynamics and properties.
