Common Rail System Bosch The high-pressure rail gives its name to the common-rail system and binds the pump and injectors together as the central hydraulic component. Bosch Group English High-pressure rail for common-rail systems Bosch Common Rail System is modular in design. The right combination of high-pressure pump, In a common rail fuel injection system, a fuel pump pressure-feeds fuel to a common rail, which accumulates the fuel at high pressure corresponding to fuel injection pressure. An electronic control unit (ECU) drives and controls a suction control valve provided in the fuel pump to regulate a pressure-feeding amount of the fuel and to perform fuel pressure feedback control. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. 20.11.2016 · How to Repair Bosch Common Rail Injector?
