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 Oquantity calculation section calculates the amount GASoof Oin exhaust gases. CO oxidation reaction heat ΔHproduced when the calculated amount CATco of adsorbed CO reacts with the calculated amount GASoof Oin the exhaust gases is calculated by a ΔHcalculation section, and used in estimation of the temperature of the catalyst.
