| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | When a first NOX purification method is performed, the catalyst temperature is lowered by extending the injection period of hydrocarbons from a hydrocarbon feed valve. In an internal combustion engine, a hydrocarbon supply valve (15) and an exhaust purification catalyst (13) are arranged in an engine exhaust passage. When hydrocarbons are injected from the hydrocarbon feed valve (15) with a period within a predetermined range and NOx contained in the exhaust gas is reduced by the reducing intermediate produced thereby, the exhaust gas When the temperature of the purification catalyst (13) exceeds a predetermined temperature that causes a reduction in the NOx purification rate, hydrocarbons from the hydrocarbon feed valve (15) are used to reduce the temperature of the exhaust purification catalyst (13). And the injection amount of hydrocarbons from the hydrocarbon feed valve (15) is increased. [Selection] Figure 20 |
