Type of common rail fuel injection system in the 20th century 90 s only officially entered the stage of practical application.This kind of electric control system can be divided into: accumulator type electronic control fuel injection system, the hydraulic pressure type electronic control fuel injection system and high pressure common rail electronically controlled fuel injection system.High pressure common rail system can be realized in traditional injection system cannot achieve function, its advantages are:1. Injection pressure common rail system of the flexible adjustable, can determine the optimal injection pressure of different conditions, thus optimizing diesel engine comprehensive performance.2. Can independently of the flexible control of fuel injection timing, with the high injection pressure (120 mpa to 200 mpa), at the same time control NOx and particles (PM) in smaller ＆#118alues, in order to meet the emission requirements.3. The flexible control of fuel injection rate, the realization of the ideal fuel injection law, easy injection and injection for many times, can reduce diesel engine NOx, and can guarantee good performance and fuel economy.4. Oil is controlled by solenoid valve, the control accuracy is higher, there will be no bubbles and residual pressure in high pressure oil to the phenomenon of zero, so in the range of the diesel engine running cycle fuel injection quantity changes little, uneven each cylinder oil can be improved, so as to reduce the vibration of the diesel engine and reduce emissions.
