摘要： An exhaust purification system including a particulate filter, a selective reduction catalyst provided at a downstream side from the filter, an ammonia ingredient feed device which feeds an ammonia ingredient to the selective reduction catalyst, a control device which controls the amount of the ammonia ingredient which is adsorbed at the selective reduction catalyst to become a target adsorption amount, and a filter regeneration system which performs filter regeneration processing to remove PM which has built up on the particulate filter when an execution start condition stands. When removal of PM is demanded, so long as the execution start condition of the filter regeneration processing by the filter regeneration system does not stand, the target adsorption amount is decreased a plurality of times in stages, and the execution start condition of the filter regeneration processing is changed to a different condition at each stage of the target adsorption amount.

摘要： A temperature sensor includes temperature detecting means and at least one of a catalyst and an adsorbent applied to the surface of the temperature detecting means. At least one of the catalyst and the adsorbent catalyzes an exothermic reaction of a reactant in gas on the temperature detecting means. A temperature that is increased by the exothermic reaction is detected by the temperature detecting means. The catalytic efficiency for the exothermic reaction of at least one of the catalyst and the adsorbent is reduced by sulfur poisoning. The temperature sensor is disposed upstream of an exhaust purification system. Accordingly, it is determined that the temperature sensor is subjected to sulfur poisoning if the temperature detected by the temperature sensor is below a prescribed temperature.

摘要： In an internal combustion engine, an NO x selective reduction catalyst (14) is arranged in an engine exhaust passage, and an NO x storage catalyst (12) is arranged in the engine exhaust passage upstream of the NO x selective reduction catalyst (14). When the amount of NO x stored in the NO x storage catalyst (12) exceeds a predetermined allowable value, the NO x storage catalyst (12) is raised in temperature to make the NO x storage catalyst (12) release the NO x . The amount of urea feed is decreased by exactly the amount of reduction of the calculated stored NO x amount with respect to the amount of urea feed determined from the engine operating state, and the amount of urea feed is increased by exactly the amount of reduction of the calculated released NO x amount with respect to the amount of urea feed determined from the engine operating state.

摘要： 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.
