Exhaust gas purification device for internal combustion engine |
| abstract |
In the internal combustion engine, a hydrocarbon supply valve (15) and an exhaust purification catalyst (13) are disposed in the engine exhaust passage. A first catalyst in which an exhaust purification catalyst (13) carries platinum (51) and a basic layer (52) on alumina (50), and a second catalyst in which rhodium (56) is supported on zirconia (55). And a mixture. The concentration of hydrocarbons flowing into the exhaust purification catalyst (13) is oscillated with an amplitude within a predetermined range of 200 ppm or more and a period within a predetermined range of 5 seconds or less, whereby in the exhaust gas The contained NO X is reduced in the exhaust purification catalyst (13). |
