Abstract
An internal combustion engine control system includes at least one cylinder having a combustion chamber configured to combust an air/fuel mixture stored therein. The air/fuel mixture is configured to combust in response to reaching an autoignition temperature. At least one electronic control module is configured to determine a chamber temperature within the combustion chamber. The electronic control module controls combustion of the air/fuel mixture based on a comparison between the chamber temperature and an autoignition temperature threshold.
