Abstract
An engine control normally effective for regulating the fuel and spark timing to provide substantially optimum engine performance. Periods of heavy operator loading are identified and integrated over time to define engine operating conditions for which engine protection concerns predominate. At such time, the normal controls are overriden to operate the engine at a reduced performance level, thereby to protect the engine from preignition damage.
