Abstract

See full text

Methods and systems are provided for improving engine spark and torque control. In one example, adaptive spark control of an engine may include a modifier that adjusts the inferred fuel octane estimate and a spark adaptation based on ambient humidity. The method allows the speed-load dependent variation in octane effect of humidity to be reduced.
