(A) the composition of common rail systems

Compared with traditional mechanical fuel injection system, electronically controlled common-rail fuel injection system-much more complex, from the pressure to produce bodies of the fuel injection control agencies have a lot of improvement. Electronic Common Rail fuel injection system and the structure of the system in Figure 2 and plans were shown in Figure 3. These mainly include: high pressure for pumps, fuel filters, the high-pressure common-rail, electronically controlled fuel injection, electronic control unit ECU, all kinds of sensors. The agency decided to improve the common rail electronic control systems to the traditional mechanical fuel injection system has many advantages.
