ABSTRACT:
Detonation (knock) control apparatus for an internal combustion engine, such as an outboard motor, comprises a transducer for sensing detonation and for providing a signal when detonation occurs to an electronic controller which then operates an electrically controllable valve to enrich the fuel/air mixture to the engine to thereby reduce detonation. The electronic controller is fail-safe and is responsive to loss of signal from the sensing device and to electrical power supply failure to operate the valve to enrich the mixture.
