Shimozi, K; Teshima, H

A monolithic catalytic exhaust gas purifier is described for an internal combustion engine. The purifier includes a cylindrical sheet metal casing having a longitudinal axis, a first end with an inlet, and a second end opposite the first end with an outlet for respectively introducing exhaust gas into and discharging exhaust gas from the casing. The casing has a flattened cross section transverse to the axis with a minimum cross dimension in one direction and a maximum cross dimension perpendicular to the one direction, a monolithic catalyst housed within the casing, and a supporting and sealing member of heat-insulating resilient material and an outer peripheral surface of the catalyst facing the flattened cylindrical wall of the casing. The supporting and sealing member exists completely around the outer peripheral circumference of the catalyst.
