    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 NOx contained in exhaust gas and reformed hydrocarbons, while the bottom coat layer (47) is comprised of an NOx 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, NOx contained in exhaust gas and NOx desorbed from the NOx absorption catalyst (47) are reduced in the exhaust purification catalyst (46).

    摘要： The present detector for detecting sulfur components includes a storage portion for storing SOx and NOx in the exhaust gas passing through an exhaust passage, in which the more an amount of stored SOx increases, the more an amount of stored NOx decreases, and which does not release SOx but release NOx at a set temperature, and a temperature sensor, estimates the amount of stored SOx on the basis of a relationship between, after the storage portion becomes the set temperature by heating, a heating pattern of the storage portion and temperature change of the storage portion measured by the temperature sensor, and detects an integrated amount of SOx passing through the exhaust passage during a given period or an value on the basis of the integrated amount.

    摘要： An exhaust purification system of an internal combustion engine has a selective reduction type NOX catalyst device which can hold ammonia and a storage reduction type NOX catalyst device which is arranged at an upstream side of the selective reduction type NOX catalyst device, which makes an air-fuel ratio of exhaust gas which flows into the storage reduction type NOX catalyst device change from a lean air-fuel ratio to a rich air-fuel ratio for starting an ammonia generation period, and which makes an air-fuel ratio of exhaust gas which flows into the storage reduction type NOX catalyst device change from a rich air-fuel ratio to a lean air-fuel ratio for ending the ammonia generation period.
