Fuel tank for automotive vehicles and evaporative emission control system incorporating same

In an evaporative emission control system including a fuel tank, a canister for adsorbing evaporative fuel generated within said fuel tank to temporarily store said evaporative fuel, and at least one evaporative fuel-guiding passage for guiding said evaporative fuel generated within said fuel tank to said canister,

• the improvement wherein said fuel tank comprises:
• a tank body for storing fuel;
• a filler pipe connected to said tank body;
• and
• a fuel outlet port device located within said tank body and connected to an end of said filler pipe, said fuel outlet port device having an upwardly facing fuel outlet opening, wherein said upwardly facing fuel outlet opening has an area which is at least larger than a cross-sectional area of said filler pipe, and said fuel tank further comprising a fuel trap for storing part of said fuel supplied through said filler pipe to thereby prevent evaporative fuel generated within said tank body from flowing into said filler pipe.

• said fuel tank including:
• a tank body for storing fuel, said at least one evaporative fuel-guiding passage being connected to said tank body;
• a float valve mounted at an end of said at least one evaporative fuel-guiding passage opening into said tank body, said float valve being located within said tank body at an upper portion thereof;
• a filler pipe connected to said tank body;
• and
• a fuel outlet port device located within said tank body and connected to said filler pipe, said fuel outlet port device having a fuel outlet opening from which fuel supplied via said filler pipe flows into said tank body;
• and
• a fuel trap for storing part of said fuel supplied through said filler pipe to thereby prevent evaporative fuel generated within said tank body from flowing into said filler pipe,
• the improvement wherein said fuel outlet opening of said fuel outlet port device faces in a direction deviating from said float valve.
