Abstract
Methods and systems are provided for a fuel vapor canister with a modular configuration that may include a number of physically and releasably coupled canister modules, each module including a temperature sensor embedded therein and filled with one of a number of adsorbents. The temperature sensors may be utilized in combination with information regarding module position and the adsorbents within each module to indicate whether one or more of the individual canister modules are not functioning as desired, where such indications are determined during either refueling events, or during canister purging events. In this way, costs associated with servicing fuel vapor canisters may be reduced, the lifetime of fuel vapor canisters may be improved, an overall reduction in undesired evaporative emissions may be achieved, and the capacity of the canister may be readily adjusted based on emissions standards.
