Vehicle refueling detection method utilizing hydrocarbon sensor

摘要

Embodiments for detecting fuel events are presented. In an embodiment, a method comprises performing an action responsive to a fuel event indicated based on output from a hydrocarbon sensor positioned between a fuel tank and a fuel vapor canister. In this way, the hydrocarbon sensor may be used to detect fuel events and engine operation may be adjusted accordingly.
