Exhaust purification system of internal combustion engine |
| abstract |
An exhaust purification system of an internal combustion engine is provided with a hydrocarbon feed valve which is arranged in an engine exhaust passage and an exhaust purification catalyst which reacts the NO X which is contained in exhaust gas and reformed hydrocarbons. It is formed to perform first operational control which feeds hydrocarbons from the hydrocarbon feed valve by within a predetermined range of amplitude and within a predetermined range of period and second operational control wherein the amount of feed of hydrocarbons from the hydrocarbon feed value in a predetermined time becomes greater than in the first operational control. In the second operational control, hydrocarbons are fed from the hydrocarbon feed valve by an injection pressure which is smaller than the injection pressure of hydrocarbons in the first operational control. |
