Abstract

In a method for monitoring an exhaust gas purifying component with gas storage capability for purifying exhaust gases from an internal combustion engine, the exhaust gas purifying component comprises a gas storage material which changes from a first state into a second state upon storage of the gas. A temperature change of the exhaust gas purifying component and/or of the gas storage material, substantially based on a heat tonality of the modification transition, is measured and evaluated.
