CONSTITUTION: A method for determining the deterioration rate of an oxidation catalyst. The actual inlet temperature of exhaust gas passing through the entrance of an oxidation catalyst(130) is measured. The temperature of the theoretical interior gas passing through the oxidation catalyst is computed using the actual inlet temperature. The theoretical outlet temperature of the exhaust gas passing through the exit of the oxidation catalyst is computed using the actual inlet temperature and the theoretical interior gas temperature. At the state excluding the oxidation heat of the oxidation catalyst, the temperature and theoretical outlet temperature of the theoretical interior gas are calculated. The actual outlet temperature of the exhaust gas passing through the exit of the oxidation catalyst is measured. The difference between the theoretical outlet temperature and the actual outlet temperature is computed. The degradation rate of the oxidation catalyst is determined by comparing the difference with the set value.
