1. for controlling and adjusting internal combustion engine(

  • 1)

    Method, wherein in normal operation adjust pressure accumulation pipe pressure(

    pCR)

    , knowingEmergency operating is switched to from normal operation, wherein pressure accumulation is improved in emergency operating when being clipped to pressure accumulating tube pressure sensor failurePipe pressure(

    pCR)

    , until a passive pressure limiting valve(

    11)

    Respond, the pressure limiting valve in the state of being opened fuel fromPressure accumulating tube(

    6)

    Leak into fuel tank(

    2)

    In, which is characterized in thatIn normal operation, as suction throttle valve(

    4)

    Trigger signal, pass through pump characteristic curve(

    16)

    Determine rated current(

    i(SL))

    , in emergency operating, pass through boundary curve(

    22)

    Determine rated current(

    i(SL))

    , to control pressure accumulation pipe pressure, byThis continuously improves pressure accumulation pipe pressure in emergency operating, until the passive pressure limiting valve responds.
