置。[Scope of claim for utility model registration] While supplying a set amount of fuel to the engine according to the engine operating conditions, the fuel evaporated in the fuel tank is temporarily adsorbed and stored in a canister filled with adsorbent. An engine that detects engine temperature in a fuel supply system for an internal combustion engine equipped with an evaporative fuel evaporation prevention device that mixes stored fuel with purge air that flows through a canister after the engine is idling and guides it to the engine's intake system. temperature detection means; fuel temperature detection means for detecting the fuel temperature directly or through temperature detection related thereto; idle state detection means for detecting the idle state of the engine; and fuel supply amount reduction correction means for reducing and correcting the fuel supply amount set based on other engine operating conditions when the fuel temperature is above a predetermined temperature and during acceleration immediately after idling. Fuel supply system for internal combustion engines.
