Abstract: The disclosure relates to a method for pressure regulation in a fuel high-pressure injection system having an overpressure valve, in which pressure pulsations occur which are caused by fuel being pumped into a high-pressure fuel accumulator and extracted from the high-pressure fuel accumulator. The method includes detecting pressure values of the fuel present in the high-pressure fuel accumulator. The method also includes comparing the detected pressure values with a nominal pressure value; and carrying out a pressure regulation in which the fuel pressure prevailing in the high-pressure fuel accumulator is set to the nominal pressure value. During pressure regulation, a peak pressure value of the detected pressure values is used as the actual pressure value. The disclosure also relates to a device for pressure regulation in a fuel high-pressure injection system.
