Abstract: An exhaust purification system of an internal combustion engine provided with an exhaust purification catalyst which reacts NOX and hydrocarbons. The exhaust purification catalyst includes an upstream side catalyst and a downstream side catalyst. The upstream side catalyst has an oxidation ability, while the downstream side catalyst carries precious metal catalyst particles on the exhaust flow surface and is formed with basic exhaust flow surface parts. The exhaust purification catalyst can make the concentration of hydrocarbons vibrate by within a predetermined range of amplitude and by within a predetermined range of period so as to partially oxidize the hydrocarbons or produce reducing intermediates at the upstream side catalyst. When the temperature of the upstream side catalyst is less than a first judgment temperature and the temperature of the downstream side catalyst is higher than a second judgment temperature, the temperature of the upstream side catalyst is made to rise.

Abstract: In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (16), an exhaust purification catalyst (13), a particulate filter (14), and an NO2 reduction catalyst (15) 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 (16). When the NO2 which is produced at the particulate filter (14) should be reduced to NO, the injection amount of hydrocarbons is increased whereby the pass through amount of hydrocarbons which pass straight through the exhaust purification catalyst (13) is increased.

Abstract: In an internal combustion engine, inside an engine exhaust passage, a hydrocarbon feed valve (15) an exhaust purification catalyst (13), and a particulate filter (14) are arranged. If the hydrocarbon feed valve (15) feeds hydrocarbons by a period of within 5 seconds, a reducing intermediate is produced inside the exhaust purification catalyst (13). This reducing intermediate is used for NOx purification processing. When the stored SOx should be released from the exhaust purification catalyst (13), the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) is made rich, the reducing intermediate built up on the exhaust purification catalyst (13) is made to be desorbed in the form of ammonia, and the desorbed ammonia is used to make the exhaust purification catalyst (13) release the stored SOx.
