  • Exhaust gas purifying system for internal combustion engine
    Patent number: 6767378
    Abstract: In an exhaust gas purifying system 1, a pair of carriers 34 is arranged in series along the flow direction of exhaust gas. Approximately a half of the exhaust gas passing through a first distribution flow path 4 flows in the upstream-side carrier 34, and the remaining half of the exhaust gas passing through a second distribution flow path 5 flows in the downstream-side carrier 34. Therefore, the capacity of the whole of the paired carriers 34 can be substantially doubled as in the case where the carriers 34 are arranged in parallel, so that the function as the exhaust gas purifying system 1 can be improved.
    Type: Grant
