Abstract:
1. A method for controlling a dethrottled internal combustion engine, the engine having a shared fresh gas line supplying fresh gas to a plurality of fresh gas pipes, each fresh gas pipe carrying fresh gas to one cylinder, at least one intake valve per cylinder, a clocked valve for each fresh gas pipe for opening and closing the respective fresh gas pipe, and a fuel injector per cylinder for metered addition of fuel, the method comprising the following steps: adjusting a chronological position of an injection time of fuel for each cylinder as a function of a point in time of a change in a switch position of the respective clocked valve; and controlling the clocked valves so that the metered addition of fresh gas is thus performed for the respective cylinder, said step of controlling taking place at least during partial-load operation of the internal combustion engine so that at least two fresh gas charging phases spaced a distance apart from one another in time are performed during one intake stroke with each cylinder.
