Abstract

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.
