Abstract (en)

[origin: WO2012062522A2] The invention relates to a method for operating an internal combustion engine. The internal combustion engine comprises a high-pressure accumulator (13) and a low-pressure region (8). The high-pressure accumulator (13) and the low-pressure region (8) are connected via a pressure control valve (10). In the method, an open position of the pressure control valve (10) is dependent on an actuating pressure. A negative load change of the internal combustion engine is detected. The actuating pressure is reduced from an initial level to a low level at a point in time dependent on the detection of a negative load change.
