Abstract
A method for operating an internal combustion engine is described. The internal combustion engine includes a high-pressure accumulator and a low-pressure area. The high-pressure accumulator and the low-pressure area are connected via a pressure control valve. An open position of the pressure control valve is a function of a control pressure. A negative load change of the internal combustion engine is detected. The control pressure is reduced at a point in time from a starting level to a low level as a function of the detection of a negative load change.
