Abstract
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, in which a set injection quantity is computed at least as a function of an actual speed relative to a set speed. An injection time for controlling an A-side injector is computed by an injector map as a function of the set injection quantity and as a function of an A-side actual rail pressure. The injection time for controlling a B-side injector is computed by the same injector map as a function of the set injection quantity and as a function of a B-side actual rail pressure.
