Abstract (en)

[origin: WO2008019919A1] Method for the determination of a rail pressure nominal value (P_Rail_Nominal) for a high-pressure rail of an internal combustion engine, wherein the rail pressure nominal value is changed at a maximum using a maximum gradient (Rail_P_SetPointInc) for the modification of the rail pressure nominal value (P_Rail_Nominal), and the maximum gradient (Rail_P_SetPointInc) is taken from an operating point (Rail_dpSetPointIncOfs_Map) as a function of the operating parameters of the internal combustion engine. The operating parameters comprise a shifted gear (Gearbx_stGear) of a gear changing mechanism.
