Exhaust purification system of internal combustion engine |
| abstract |
In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve ( 15 ) and an exhaust purification catalyst ( 13 ) are arranged. At the time of engine operation, the amplitude of change of the concentration of hydrocarbons which flow into the exhaust purification catalyst ( 13 ) is made to become within a predetermined range of amplitude by control of the injection amount of hydrocarbons from the hydrocarbon feed valve ( 15 ), the concentration of hydrocarbons flowing into the exhaust purification catalyst ( 13 ) is made to vibrate by a predetermined range of period by control of the injection period of hydrocarbons from the hydrocarbon feed valve ( 15 ), and thereby the NO x contained in the exhaust gas and the NO x stored in the exhaust purification catalyst ( 13 ) are reduced. |
