摘要： An object of the present invention is to appropriately remove, from an exhaust gas, HC, CO, and ammonia flowing out from a filter (SCRF) on which an SCR catalyst is carried. In the present invention, a post-catalyst 8 is provided for an exhaust gas passage of an internal combustion engine on a downstream side from SCRF along with a flow of the exhaust gas. The post-catalyst 8 is constructed to include an adsorption reduction part 81c which adsorbs ammonia and which reduces NOx by using ammonia as a reducing agent, a first oxidation part 81b which oxidizes ammonia, and a second oxidation part 82 which oxidizes HO and CO.

摘要： An exhaust gas purification filter that is suitable for arrangement in an exhaust passage of an internal combustion engine and for collecting particulate matter contained in exhaust gas, comprises: exhaust gas inflow passages and exhaust gas outflow passages that are arranged alternately; and porous partitions that separate the exhaust gas inflow passages and the exhaust gas outflow passages from each other. Each of the partitions is divided into a coated zone in which a surface of a partition base is coated with a coating layer having a smaller average pore diameter than an average pore diameter of the partition base and a non-coated zone that is located on a downstream side of the coated zone and in which a surface of the partition base is not coated with the coating layer. A pore diameter of the partitions is set such that ash contained in the exhaust gas is able to pass through the partitions in the non-coated zone. A passage resistance of a partition portion located in the coated zone, the passage resistance being in a thickness direction of the partition portion located in the coated zone, is lower than a passage resistance of a partition portion located in the non-coated zone, the passage resistance being in a thickness direction of the partition portion located in the non-coated zone.

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： An exhaust purification system in which when an air-fuel ratio of exhaust gas is leaner than a stoichiometric air-fuel ratio, a silver-alumina-based catalyst device releases adsorbed NO2 at a first set temperature and releases adsorbed NO at a second set temperature which is lower than the first set temperature. When the air-fuel ratio of the exhaust gas is leaner than the stoichiometric air-fuel ratio and the silver-alumina-based catalyst device is a third set temperature which is lower than the second set temperature, a temperature rise of the silver-alumina-based catalyst device is suppressed to maintain the silver-alumina-based catalyst device near the third set temperature, and at least part of the NO which is adsorbed at the silver-alumina-based catalyst device is oxidized to NO2 to be adsorbed at the silver-alumina-based catalyst device, then the suppression of the temperature rise of the silver-alumina-based catalyst device is lifted.

摘要： In an internal combustion engine, inside of an engine exhaust passage, an NOx adsorption part and an NOx purification part are arranged. The NOx purification part has the property of reducing NOx 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 NOx is to be desorbed from the NOx adsorption part, the current NOx which is contained in the exhaust gas and the NOx which is desorbed from the NOx adsorption part are reduced by making the concentration of hydrocarbons of the NOx 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.
