Abstract
A method and a system for regenerating an exhaust gas treatment device for an internal combustion engine having at least one cylinder are presented. The system comprises an exhaust gas treatment device, a fuel storage means, a fuel vapor retainer, and an engine control unit adapted to selectively allow fuel vapors from the fuel vapor retainer to reach the engine. The method comprises regenerating an exhaust gas treatment by allowing fuel vapors from the fuel vapor retainer into at least one of the engine cylinders, and inhibiting combustion in at least one of the cylinders into which fuel vapors are to allowed.
