Abstract:
A method for operating an internal combustion engine including an engine of a motor vehicle, the method comprising the steps of:injecting fuel directly into the combustion chamber either in a first operating mode (VH) during a compression phase or in a second operating mode (SH) during an induction phase; switching over between the two operating modes (VH, SH); controlling (open loop and/or closed loop) the injection duration (ti), which influences the injected fuel mass, differently in the two operating modes (VH, SH); and, when switching from the first operating mode (VH) into the second operating mode (SH), influencing the injection duration (ti) via a function (Fti-SH-inst) which runs from a positive start value, which is greater than 1, to an end value 1.
