Abstract
Methods are provided for controlling an engine in response to a pre-ignition event. A pre-ignition threshold and a pre-ignition mitigating action are adjusted based on a rate of change of cylinder aircharge. As a result, pre-ignition events occurring during transient engine operating conditions are detected and addressed different from pre-ignition events occurring during steady-state engine operating conditions.
