摘要： In an exhaust purification system of an internal combustion engine of the present invention, a silver-alumina-based catalyst device and NO x reducing catalyst device are arranged in the engine exhaust system. When a temperature of the silver-alumina-based catalyst device becomes a first set temperature T1 on the high temperature side (step 110), NO x released from the silver-alumina-based catalyst device is reduced by reducing material to be purified in the NO x reducing catalyst device (step 115). When the temperature of the silver-alumina-based catalyst device becomes a second set temperature on the low temperature side (step 104), NO x released from the silver-alumina-based catalyst device is reduced by reducing material to be purified in the NO x reducing catalyst device (step 107).

摘要： In an internal combustion engine, inside of an engine exhaust passage, an NO x adsorption part and an NO x purification part are arranged. The NO x purification part has the property of reducing NO x which is contained in exhaust gas if the concentration of hydrocarbons is made to vibrate by within a predetermined range of amplitude and within a predetermined range of period. When NO x is to be desorbed from the NO x adsorption part (at step 203), the current NO x which is contained in the exhaust gas and the NO x which is desorbed from the NO x adsorption part are reduced by making the concentration of hydrocarbons of the NO x purification part vibrate by the amplitude and period which are set for the current engine operating state, at least of which (ΔT·k) has been corrected so that the amount of hydrocarbons becomes greater (step 205).

摘要： In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust treatment catalyst (13) are arranged. On a substrate (45) of the exhaust treatment catalyst (13), a coat layer comprised of at least two layers of a top coat layer (46) and a bottom coat layer (47) is formed. The top coat layer (46) is comprised of an exhaust purification catalyst for reacting NO x contained in exhaust gas and reformed hydrocarbons, while the bottom coat layer (47) is comprised of an NO x absorption catalyst. The concentration of hydrocarbons which flows into the exhaust treatment catalyst (13) is made to vibrate within a predetermined range of amplitude and within a predetermined range of period. Due to this, NO x contained in exhaust gas and NO x desorbed from the NO x absorption catalyst (47) are reduced in the exhaust purification catalyst (46).
