Abstract
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.
