Claim Text:
1. A method for operating an internal combustion engine, the internal combustion engine including a high-pressure accumulator and a low-pressure area, the high-pressure accumulator and the low-pressure area being connected via a pressure control valve, an open position of the pressure control valve being a function of a control pressure, the method comprising: detecting a negative load change of the internal combustion engine; reducing the control pressure at a point in time from a starting level to a low level as a function of the detection of a negative load change, the control pressure remaining at the low level for a time period from the point in time to another point in time; and returning the control pressure approximately to the starting level at the other point in time, a time period between the point in time and the other point in time being ascertained as a function of a rotational speed of the internal combustion engine.
