Abstract
A method for operating an internal combustion engine: detecting a first signal from a knock sensor in a temporal measurement window for a first load point and for a first energization duration—assigned to a pre-injection—of an injector for an operating cycle; calculating a first first evaluation point from the first signal by a first metric; detecting a second signal from the knock sensor in the temporal measurement window for the first load point and for a second energization duration—assigned to the pre-injection—of the injector for the operating cycle; calculating by the first metric a second first evaluation point from the second signal; determining an optimum energization duration as an optimum of the first first evaluation point and the second first evaluation point; and storing and/or applying the optimum energization duration to the first load point and the first combustion chamber.
