Abstract
A method for improving purging of fuel vapors from a fuel vapor storage canister to an engine is presented. In one example, the method adjusts engine operation to provide sonic flow between a canister and the engine. In this way, it may be possible to lower an amount of fuel vapors stored in a canister while the engine continues to operate efficiently.
