ABSTRACT:
A method and an arrangement for regulating the signal level in detecting knocking in an internal combustion engine. A transducer, incorporated in a knocking detector, senses a parameter responding to pressure and/or temperature during combustion in the engine and emits a signal representing the degree of knocking. The output signal of the knocking detector controls a knocking-regulating quantity affecting combustion in the engine by being applied to a signal level limiting block which, when knocking sensed by the transducer exceeds a preselected level, limits the output signal level to a level corresponding to said preselected level, whereafter the output signal, at least for a limited time, can only be altered by signals representing a lesser degree of knocking than the preselected degree. Knocking can then be inhibited without delay.
