  • Method and system for reducing engine spark knock during a rapid transient
    Patent number: 5445127
    Abstract: A method and system is provided for reducing engine spark knock during rapid transient operating conditions. The method includes the step of determining, at periodic intervals, an estimate of airflow into a combustion chamber. The method also includes the step of determining, at periodic intervals, whether rapid transient operating conditions exist. If such conditions exist, an estimated spark advance is determined based on the estimated airflow. Finally, a spark is fired in the combustion chamber based on the estimated spark advance parameter.
