Exhaust purification system of internal combustion engine |
| abstract |
A hydrocarbon feed valve and an exhaust purification catalyst are arranged in an engine exhaust passage. A first NO X purification method which injects hydrocarbons from the hydrocarbon feed valve by a predetermined period to thereby remove NO X which is contained in the exhaust gas and a second NO X purification method which makes the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst rich to make the exhaust purification catalyst release the stored NO X when the NO X which is stored in the exhaust purification catalyst exceeds a first allowable value are selectively used. Hydrocarbons are injected from the hydrocarbon feed valve by the predetermined period, and when the NO X which is stored in the exhaust purification catalyst exceeds a second allowable value which is smaller than the first allowable value, the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst is made rich. |
