Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of accurately estimating a purge flow rate which is to be reflected to air/fuel ratio control. SOLUTION: The weight of a canister 31 is measured. The purge flow rate of evaporation fuel during purging of the evaporation fuel is estimated according to increase amount of the obtained weight due to adsorption of the evaporation fuel of the canister 31 and intake pressure generating in an intake system of an engine during purging of the evaporation fuel. Therefore, the purge flow rate is accurately estimated. COPYRIGHT: (C)2009,JPO&INPIT
