| titleOfInvention | Exhaust gas purification method |
| abstract | A conventional exhaust gas purification method oxidizes and removes gas components such as HC and CO by a precious metal-supporting honeycomb in the previous stage, further oxidizes NO to NO 2, and utilizes the oxidizing power of NO 2 to convert PM. Since it is a system that undergoes oxidative decomposition, there is a problem in that exhaust gas purification performance deteriorates when PM covers the surface of the noble metal. In the exhaust gas purification method of the present invention, a CCV-supported DPF 4 and a Pt-supported honeycomb 5 are disposed in the filter case 1 at the front stage and the Pt-supported honeycomb 5 at the rear stage with respect to the exhaust gas flow. Diesel exhaust gas containing PM, HC, CO, NO, etc. first passes through the CCV-supported DPF 4 and PM is collected. The collected PM is oxidized and burned by the action of the CCV and becomes a gas component such as CO or CO 2 and passes through the Pt-supporting honeycomb 5 at the subsequent stage, so that PM does not flow into the Pt-supporting honeycomb 5. . Further, the gas component that has passed through the Pt-supporting honeycomb 5 is oxidized by the action of Pt. [Selection] Figure 3 |
