A method for controlling fueling of an engine, the method comprising during an engine cold start and before the engine is warmed to a predetermined level, transitioning from open-loop fueling to closed-loop fueling, where during closed-loop fueling feedback from an exhaust gas oxygen sensor is utilized and where said closed-loop fueling generates a cycling of delivered fuel in maintaining exhaust air-fuel ratio at a desired level; and providing a fueling adjustment to a subsequent engine start in response to fueling information, said fueling information obtained over at least a complete cycle of closed-loop fueling following said transition from open-loop fueling.

Cold idle adaptive air-fuel ratio control utilizing lost fuel approximation

A method to deliver fuel during a start for an internal combustion engine is described. The method provides individual cylinder fuel control based on the number of fueled cylinder events. The method offers improved engine emissions while maintaining engine run-up performance.

Cylinder event based fuel control

Provided is a method and apparatus for statistically detecting knock borderline and evaluating knock intensity in an internal combustion engine having at least one cylinder.
