Abstract: An exhaust gas control system for an internal combustion engine, before execution of a filter regeneration process, executes a pre-regeneration process that is a process of raising a temperature of a filter to a second target temperature lower than a first target temperature and increasing the concentration of NO 2 contained in exhaust gas flowing into the filter for a predetermined period. The first target temperature during execution of the filter regeneration process in the case where a speed of change in a detected value of a differential pressure sensor during execution of the pre-regeneration process is high is set so as to be lower than the first target temperature in the case where the speed of change is low.

Abstract: An exhaust purification system of an internal combustion engine comprising an exhaust treatment catalyst (13) arranged in an engine exhaust passage and a heat and hydrogen generation device (50) able to feed only heat or heat and hydrogen to the exhaust treatment catalyst (13). When the warm-up operation of the heat and hydrogen generation device (50) is completed and a reforming action by a reformer catalyst (54) becomes possible, if the temperature of the exhaust treatment catalyst (13) is a preset activation temperature or more, a partial oxidation reaction is performed at the heat and hydrogen generation device (50) and the generated heat and hydrogen are fed to the exhaust treatment catalyst (50). If the temperature of the exhaust treatment catalyst (13) is less than the preset activation temperature, a complete oxidation reaction by a lean air-fuel ratio is continued and a heat is fed to the exhaust treatment catalyst (13).
