1. A method for operating an internal combustion engine, comprising:

  • performing, in at least one cylinder, combustion of a fuel in a fuel-air mixture introduced into the at least one cylinder;

    influencing at least one physical process by at least one adjusting device;

    modifying a distribution of at least one of constituents and an overall composition of the fuel-air mixture in the at least one cylinder by the at least one physical process;

    retarding gradually, when a knock occurs, an ignition angle in the at least one cylinder by a knock control from a fundamental ignition angle by an adjustment angle; and

    reducing rapidly, by increments, the adjustment angle if at least one of an adjustment of the at least one adjusting device exceeds a specifiable first threshold and a change in the at least one physical process exceeds a specifiable second threshold, wherein a more rapid reduction occurs with at least one of a larger increment and a higher frequency of increments.
