Abstract
An evaporated fuel control system in internal combustion engines includes a canister filled with an adsorbent for adsorbing an evaporated fuel in a fuel tank, a purge amount control device provided in the middle of a purge passage connecting an intake passage and the canister, and a fuel supply device. The purge flow rate from the start of purging is integrated, and the purge amount is reduced to a larger extent in response to a purge amount integration value becoming smaller. This improves the nature of an exhaust gas immediately after the start of purging and the like.
