ABSTRACT:
In a fuel cut period, an adsorbed CO quantity calculation section calculates the amount CATco of CO adsorbed on a catalyst, and an exhaust O2quantity calculation section calculates the amount GASo2of O2in exhaust gases. CO oxidation reaction heat ΔHrproduced when the calculated amount CATco of adsorbed CO reacts with the calculated amount GASo2of O2in the exhaust gases is calculated by a ΔHrcalculation section, and used in estimation of the temperature of the catalyst.
