Abstract
A detector for detecting sulfur components having a storage portion for storing SOX and NOX in the exhaust gas passing through an exhaust passage and a temperature sensor for measuring a temperature of the storage portion. The detector includes a heater for heating the storage portion and determines the current heat capacity (C) of the storage portion on the basis of an increase in (T2−T1) the temperature of the storage portion measured by the temperature sensor and a quantity of heat (QH) generated by the heater when the heater heats the storage portion.
