Abstract:
1. In a method of controlling an internal combustion engine ( 1 ) with common rail fuel injection comprising the steps of: calculating a fuel injection begin (SB) depending at least on an actual engine speed (nM(IST)), calculating an injection begin correction (dSB) from a deviation (dLM) of a desired intake air mass flow (LM(SL) from an actual intake air mass flow (LM(IST)) and calculating from the injection begin (SB) and the injection begin correction (dSB) a resulting injection begin (SB(RES)) for controlling the internal combustion engine, the improvement, wherein the desired intake air mass flows (LM(SL)) is calculated depending on the actual engine speed (mM(IST)) and one of a desired engine torque (MSW) and a filtered desired engine torque (MSW(F)) and in the calculation of the desired intake air mass flow (LM(SL)) an operating state of an exhaust gas turbocharger MOD(ATL)) is taken into consideration in the form of a single charger operation or a multi-charger charger operation.
