How injection pressure is controlled in a comon rail fuel system

  • In common rail system of fuel injection, common piping supplies fuel to the individual injectors by a branch pipe which is the feature of the common rail system. This pipe and the full system is under high pressure i.e. the injection pressure. 
  • To control this, a bypass valve is utilized which is fitted at the end of the common pipe.
  • By closing or opening this valve, more or less, the fuel is bypassed from the system back to the suction of the pump, thus reducing the pressure.
