摘要: Methods and systems are provided for mitigating knock and/or pre-ignition. Each of a spark timing retard, cylinder enrichment, and engine load limiting is adjusted based on a knock sensor output generated in a single defined crank angle window, and not based on knock sensor output generated outside the defined crank angle window. A severity of the mitigating actions is adjusted in proportion to the knock sensor output intensity with the severity of the mitigating action increased as the knock sensor output intensity increases.

摘要: Methods and systems are provided for pre-ignition control. A pre-ignition mitigating enrichment is deactivated in response to a tip-out but reactivated in response to a subsequent tip-in. By preemptively enriching the engine, repeated pre-ignition due at subsequent tip-ins is reduced.
