ABSTRACT:
A catalytic converter has a honeycomb catalyst body, a housing and a holding material, wherein the honeycomb catalyst body has, as the catalyst carrier, a honeycomb structure having an inner wall(s) which is (are) provided so as to divide the large number of cells into two or more cell blocks and which has (have) a thickness larger than the thickness of the partition walls, and the exhaust gas-incoming section and purified gas-outgoing section of the housing are divided by diaphragms into two or more exhaust gas-incoming passages and two or more purified gas-outgoing passages, and the two or more cell blocks of the honeycomb structure are allowed to communicate with the corresponding two or more exhaust gas-incoming passages and corresponding two or more purified gas-outgoing passages of the housing. This catalytic converter has a compact structure and can effectively prevent the reduction in engine output caused by exhaust gas interference, without adoption of complicated exhaust pipe structure, or increase in vehicle body weight, or increase in cost.
