Abstract
The present detector for detecting sulfur components includes a storage portion for storing SOand NOin the exhaust gas passing through an exhaust passage, in which the more an amount of stored SOincreases, the more an amount of stored NOdecreases, and which does not release SObut release NOat a set temperature, and a temperature sensor, estimates the amount of stored SOon the basis of a relationship between, after the storage portion becomes the set temperature by heating, a heating pattern of the storage portion and temperature change of the storage portion measured by the temperature sensor, and detects an integrated amount of SOpassing through the exhaust passage during a given period or an value on the basis of the integrated amount.
