ABSTRACT:
A method for controlling a dethrottled internal combustion engine, which has a shared fresh gas line which supplies fresh gas to fresh gas pipes, which in turn supply fresh gas to each cylinder. The engine has at least one intake valve per cylinder, a clocked valve per fresh gas pipe for opening and closing the gas pipe and a fuel injector for each cylinder, for metered addition of fuel. The chronological location of the injection time of the fuel is adjusted for the respective cylinder as a function of a point in time of a change in the switch position of the respective clocked valve, to improve the emission values of the engine. In addition, the clocked valves are controlled so that the metered addition of fresh gas is accomplished for the respective cylinder.
