SYSTEM AND METHODS FOR PURGING RESIDUAL EXHAUST AND UNCOMBUSTED FUEL TO A FUEL VAPOR CANISTER |
摘要 |
A method for an engine is presented, comprising, following an engine-off event, positioning a first engine cylinder with an intake valve open, opening a canister purge valve; and purging contents of the first engine cylinder to a fuel vapor canister. In this way, uncombusted fuel that may otherwise be emitted from the engine during a prolonged diurnal soak may be stored within the fuel vapor canister, thus decreasing overall vehicle emissions. |
