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: A particulate filter (23) for trapping the particulate matter which is contained in the exhaust gas is provided inside an engine exhaust passage. Additional fuel is secondarily injected from a fuel injector (3) in an engine expansion stroke or exhaust stroke or hydrocarbons are secondarily added from an addition valve (24) which is provided upstream of the particulate filter in the exhaust pipe (21). An amount of hydrocarbons which come from the fuel injector (3) or addition valve (24) and then adhere in the form of a liquid to the inflow end of the particulate filter, and an amount of particulate matter which reaches the inflow end of the particulate filter are respectively estimated. A degree of clogging at the inflow end of the particulate filter is estimated based on the amount of hydrocarbons and the amount of particulate matter.

Abstract: An internal combustion engine which is provided with a hydrocarbon feed valve (15) arranged in an engine exhaust passage. When injection control for injecting hydrocarbons from the hydrocarbon feed valve (15) for exhaust treatment is stopped, to prevent the hydrocarbon feed valve (15) from clogging, hydrocarbons for preventing clogging are injected from the hydrocarbon feed valve (15) when the engine is not discharging soot, that is, when the feed of fuel to the inside of the combustion chamber (2) is stopped and, after hydrocarbons for preventing clogging are injected once, the injection of hydrocarbons for preventing clogging from the hydrocarbon feed valve (15) is stopped until injection control for exhaust treatment is started.
