Abstract
Methods and systems are described for engine idle speed optimization. A system may include determining whether a fuel intake rate indicative of an amount of fuel consumed by an idling engine over time satisfies a threshold in comparison to a reference fuel intake rate. The reference fuel intake rate may be indicative of a predetermined amount of fuel consumed by the idling engine over time. The system may adjust a predetermined minimum speed at which the engine idles in response to determining that the fuel intake rate satisfies the threshold.
