Abstract
An internal combustion engine, wherein fuel vapor adsorbed in a canister (22) is purged into a surge tank (13) through a purge control valve (28). A target value of the fuel vapor rate showing the ratio of the amount of fuel vapor in the purge gas to the amount of fuel injection is stored in advance. At least one of the amount of purge gas or the amount of fuel injection is controlled so that the fuel vapor rate becomes the target value.
