Abstract: A temperature sensor (10) 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 (10) is disposed upstream of an exhaust purification system (30). 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.

Abstract: An exhaust purification system of an internal combustion engine arranging in an engine exhaust passage an NOx storing reducing catalyst storing NOx contained in exhaust gas when an air-fuel ratio of inflowing exhaust gas is lean and reducing and purifying stored NOx when the air-fuel ratio of the inflowing exhaust gas becomes a stoichiometric air-fuel ratio or rich, which system is provided with an NOx production reducing means for reducing an amount of production of NOx produced in a combustion chamber due to change of a combustion state of the engine and temporarily reduces the amount of production of NOx by the NOx production reducing means when an amount of N 2 O flowing out from the NOx storing reducing catalyst is anticipated to exceed an allowable amount.
