SYSTEM AND METHODS FOR PURGING A FUEL VAPOR CANISTER |
| 摘要 |
A method for purging a fuel vapor canister, comprising: responsive to an indication of vapor slugs, reversing a direction of air flow through the fuel vapor canister while maintaining purge air intake at a vent line inlet. By reversing the direction of air flow through the fuel vapor canister, the vapor slugs may be adsorbed within the fuel vapor canister and may not affect engine operation. In this way, purge operation may be maintained and emissions may be reduced. |
