Abstract
A device for catalytic purification of exhaust gas from an internal combustion engine includes a housing and a catalyst carrier mounted within the housing. The device communicates with the exhaust line from the engine so that exhaust gas flows through the catalyst carrier, entering and exiting from the carrier through different ends of the carrier. Disposed within the housing of the device adjacent at least one end of the carrier is a heat shield. The shield protects a wall of the housing against the heat from the exhaust gas flowing through the housing. The heat shield is particularly suitable for a catalytic purification device in which the catalyst carrier is mounted in the housing by an elastic support compressed between the carrier and the housing.
