Abstract
Official abstract text for this publication.
Methods and systems for detecting a refueling event for diagnostics are disclosed. In one example approach a method comprises discontinuing leak diagnostics in response to a temperature change in a fuel vapor canister coupled to a fuel tank in an emission control system while the leak diagnostics are being performed in the emission control system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for a vehicle with an engine comprising: discontinuing leak diagnostics in response to a temperature change in a fuel vapor canister coupled to a fuel tank in an emission control system while the leak diagnostics are being performed in the emission control system. 2. The method of claim 1 , wherein the temperature change comprises a rate of temperature change in the canister greater than a threshold.…
