ABSTRACT:
An exhaust gas purifying apparatus includes a carrier of a honeycomb structure which is made of at least one flat metal plate and at least one corrugated metal plate which is superimposed on the flat metal plate. A catalytic layer is formed on the surface of the carrier. The carrier suited for being coated with the catalytic layer is disposed in an exhaust pipe of an internal combustion engine. The carrier is provided, on an axially intermediate portion thereof, with a large number of louvers which causes a haphazard secondary motion in the exhaust gas. A predetermined portion of the carrier including the turbulence producing portion and an additional region located adjacent to said predetermined region is coated with a larger amount of catalyst than that with which the remaining portion of the carrier is coated, whereby good purifying efficiency can be obtained for a long time.
