Abstract
Energy to speed heating of a catalyst associated with an internal combustion engine can be provided in the form of sensible energy (heat) via hot combustion products. In some variations, timing of opening and/or closing of an exhaust valve can be manipulated to increase sensible heat delivered to the catalyst in the exhaust gases.
