A method of avoiding abnormal combustion, so-called knocking, in an internal combustion engine, where a parameter representative of the combustion conditions in the engine is monitored. When abnormal combustion occurs, a signal representing such abnormal combustion is generated and is used to initiate an adjustment of the engine operating conditions by lowering the engine induction pressure so as to reestablish normal combustion. There is also provided an arrangement for avoiding abnormal combustion.

A method of avoiding abnormal combustion, so-called knocking, in a supercharged internal combustion engine, comprising the steps of monitoring a parameter representative of the combustion conditions prevailing in the engine, generating a first signal representing said parameter, sensing the engine speed, generating a second signal proportional to the engine speed and representing optimum combustion in the engine, comparing said first signal with said second signal to obtain a deviation signal, whereby, when abnormal combustion occurs in the engine, said deviation signal initiates an adjustment of the engine operating conditions for eliminating abnormal combustion, wherein the engine operating conditions are adjusted by reducing the engine induction pressure in response to the magnitude of said deviation signal to a level providing normal combustion.
