    摘要: 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.
