    Abstract: A catalytic converter has a cylindrical can with open ends. Exhaust gases admitted through one end may flow through a first catalyst bed to openings in the side wall of the can or through the narrow end of a funnel shaped container projecting through an opening in the center of the first catalyst bed. A second catalyst bed, coaxial with the first, is placed in the wide end of the funnel shaped container to increase the catalyst bed flow area. A housing containing the can has walls which define an annular passage around the can through which the exhaust gases flow upon emerging from the beds to increase heating of the catalyst beds for faster catalyst warm-up.

    Abstract translation: 催化转化器具有开口端的圆筒形罐。 通过一端容纳的废气可以通过第一催化剂床流到罐的侧壁中的开口或通过在第一催化剂床的中心突出的漏斗形容器的窄端。 与第一催化剂床同轴的第二催化剂床被放置在漏斗形容器的宽端,以增加催化剂床流动面积。 容纳罐的壳体具有限定围绕罐的环形通道的壁,当从床上出来时废气流过该环状通道,以增加催化剂床的加热以实现更快的催化剂预热。
