Abstract
An exhaust system used for a motor vehicle and extending between an exhaust-generating internal combustion engine and an exhaust pipe for release of exhaust into the surrounding environment, includes a three-way catalytic converter disposed in proximity of the combustion engine, a NO -adsorber disposed upstream of the exhaust pipe, and an exhaust line, which extends between the catalytic converter and the NO -adsorber, for conducting exhaust. The exhaust line includes an inner tube, an outer tube in spaced-apart surrounding relationship to the inner tube to define a space, and a separation tube received in the space, to thereby define between the inner tube and the separation tube an inner annular gap for conducting exhaust, and between the outer tube and the separation tube an outer annular gap for conducting a coolant. A shut-off device is integrated in the inner tube for regulating the flow of exhaust through the inner tube.
