Abstract:
Methods and systems are provided for increasing an efficiency of a purging operation of a fuel vapor storage canister of a vehicle, the fuel vapor storage canister configured to capture and store fuel vapors stemming from a fuel tank of the vehicle. As one example, a method comprises reactivating one or more cylinders of an engine during a purging operation, in response to an indication that the purging of stored fuel vapors from the fuel vapor storage canister is compromised as a result of fuel vaporization stemming from the fuel tank. In this way, the canister may be effectively cleaned even under high fuel vaporization circumstances, which may improve fuel economy and may reduce release of undesired evaporative emissions to atmosphere.
