SYSTEMS AND METHODS FOR REDUCING BLEED EMISSIONS |
| 摘要 |
A method for a fuel system, comprising: during a first condition, including an engine-off condition and a sealed fuel tank, directing fresh air into a fuel vapor canister responsive to detecting hydrocarbons in a canister vent line. By directing fresh air into the fuel vapor canister, fuel vapor stored within the canister may be redistributed away from the canister vent line. In this way bleed emissions from the fuel system may be reduced without the need for a dedicated bleed canister. |
