Abstract:
1. A method for controlling a V-type internal combustion engine with a separate common rail system on an A side and a separate common rail system on a B side of the internal combustion engine, comprising the steps of: computing a set injection quantity (QSL) at least as a function of an actual speed (nIST) relative to a set speed (nSL), computing an injection time (SD) for controlling an A-side injector by an injector map as a function of the set injection quantity (QSL) and as a function of an A-side actual rail pressure (pIST(A)); and computing an injection time (SD) for controlling a B-side injector by the same injector map as a function of the set injection quantity (QSL) and as a function of a B-side actual rail pressure (pIST(B)), including switching from the A-side actual rail pressure (pIST(A)) as an input variable of the injector map to the B-side actual rail pressure (pIST(B)) as the input variable of the injector map or vice versa as a function of firing order (ZF).
