摘要： An exemplary embodiment of the present disclosure relates to a selective catalytic reduction and catalytic regeneration system, and the selective catalytic reduction and catalytic regeneration system includes: a main exhaust flow path along which exhaust gas containing nitrogen oxide moves; a reactor which is installed on the main exhaust flow path and includes a catalyst for reducing nitrogen oxide in the exhaust gas; a bypass exhaust flow path which branches off from the main exhaust flow path, bypasses the reactor, and merges with the main exhaust flow path again; an ammonia injection unit which is installed on the main exhaust flow path, and injects ammonia to the exhaust gas which is to flow into the reactor; a hydrolysis chamber which is supplied with urea, and produces ammonia to be supplied to the ammonia injection unit; an ammonia supply flow path which connects the ammonia injection unit with the hydrolysis chamber; a branch flow path which branches off from the main exhaust flow path at a front side of the reactor; a recirculation flow path which branches off from the main exhaust flow path at a rear side of the reactor, and merges with the branch flow path; and a multifunctional flow path which connects the hydrolysis chamber with a point where the branch flow path and the recirculation flow path merge together.

摘要： In an internal combustion engine, inside of an engine exhaust passage, an upstream side air-fuel ratio sensor (23), a hydrocarbon feed valve (15), an exhaust purification catalyst (13), and a downstream side air-fuel ratio sensor (24) are arranged in this order from the upstream. At the time of engine operation, the injection amount of hydrocarbons from the hydrocarbon feed valve (15) is controlled based on the air-fuel ratio detected by the upstream side air-fuel ratio sensor (23) and the downstream side air-fuel ratio sensor (24) so that the amplitude of change of the concentration of hydrocarbons which flow into the exhaust purification catalyst (13) becomes within a predetermined range of amplitude.

摘要： In cases where an NOx selective reduction catalyst is provided at a location downstream of an NOx storage reduction catalyst, NOx purification performance in an exhaust gas purification apparatus as a whole is maintained, irrespective of deterioration of the NOx storage reduction catalyst. For this purpose, the reduction of NOx in the NOx storage reduction catalyst is promoted more when the degree of deterioration of the NOx storage reduction catalyst or the NOx selective reduction catalyst is low than when it is high, and the reduction of NOx in the NOx selective reduction catalyst is promoted more when the degree of deterioration of the NOx storage reduction catalyst or the NOx selective reduction catalyst is high than when it is low.
