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： An object of the present invention is to suppress HC, CO, and NOx from being discharged to the outside when a filter regeneration process is executed in an exhaust gas purification system for an internal combustion engine provided with a filter including an SCR catalyst carried thereon. In the present invention, a post-catalyst is provided for an exhaust gas passage disposed on a downstream side from the filter. The post-catalyst has an oxidizing function, and the post-catalyst has such a function that the production of N2 based on the oxidation of ammonia is facilitated in a predetermined first temperature area. Further, when the filter regeneration process is executed, the temperature of the post-catalyst is adjusted to be in the first temperature area while adjusting the temperature of the filter to be in a predetermined second temperature area lower than a filter regeneration temperature during a certain period of time.

摘要： An internal combustion engine in which an SOx trap catalyst (13) for trapping SOx contained in the exhaust gas contains an oxygen adsorbing and releasing material (54) which can adsorb SO2 contained in the exhaust gas and an SOx storage material (55) which can store SOx in the form of sulfates. The SO2 which is contained in the exhaust gas is chemically adsorbed at the oxygen adsorbing and releasing material (54) without being oxidized. If the temperature of the SOx trap catalyst (13) becomes higher than the start temperature of adsorbed SO2 movement, the SO2 which is chemically adsorbed at the oxygen adsorbing and releasing material (54) is oxidized and stored in the form of sulfates in the SOx storage material (55).

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 NOx that can be stored decreases, estimates the amount of stored SOx on the basis of an amount of NOx stored in the storage portion, 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. In the present detector, the estimating of the amount of stored SOx for detecting the integrated amount of SOx or the value on the basis of the integrated amount is prohibited when a current amount of NOx that can be stored is not stored in the storage portion.
