Abstract
An auto ignition mitigation system comprises a piston position module that determines a position of a piston within a cylinder and a temperature module that determines a first temperature of air within the cylinder. A fuel enrichment module communicates with the piston position module and the temperature module and determines a first fuel quantity based on the first temperature and the position of the piston. A fuel control module communicates with the fuel enrichment module and provides the first fuel quantity to the cylinder after the engine is started and before a first exhaust stroke of the piston.
