Abstract
The present disclosure relates to a method for removing residual purge gas in operating an active purge system and includes determining evaporation gas purge stop in a control unit, closing a PCSV mounted on a purge line connecting a canister and an intake pipe, and determining whether all of the evaporation gas flowed into the intake pipe is flowed into a combustion chamber, so that all of the evaporation gas flowed into an intake pipe during travelling can be flowed into and combusted in the combustion chamber.
