Abstract
An evaporative emission control system for a plug-in hybrid electric vehicle that indicates the level of loading of a carbon canister of the system. The system has multiple thermocouples positioned space apart from each other along a vapor flow path within the carbon canister. A controller is connected to each thermocouple, which monitors the temperature of the thermocouples. The controller indicates the level of saturation of the carbon canister based on certain pre-determined temperature criteria.
