Abstract
A system for preventing knocking combustion in a turbocharged Otto engine includes a knock detector mounted on the engine block and coupled to a microprocessor which controls the engine charge pressure and ignition timing. Upon indication of a certain knocking intensity, the processor sends signals to a valve regulating the charge pressure to reduce this pressure as well as signals to the engine timing control system to retard the engine ignition timing.
