Abstract
A device for suppressing engine knocks in an internal combustion engine, using a detection device for the detection of the respective operating parameters of the internal combustion engine; a control unit for determining manipulated variables for the injection and ignition on the basis of the acquired operating parameters; a dynamic phase detection device for acquiring a dynamic phase of the internal combustion engine; and a correction device for correcting the manipulated variables for the ignition, which is constructed so that for knock suppression, the ignition control quantity, given a dynamic phase acquired by the dynamic phase detection device, can be adjusted in the late direction by a dynamic lead that is dependent on a predicted load difference, and at the end of the dynamic phase can be brought step-by-step back to the manipulated variable determined by the control unit.
