<p>The present invention provides a novel fuel tank to reduce evaporative fuel loss in a fuel tank. The novel fuel tank includes a foam and/or mesh inside to reduce the turbulence-induced evaporative fuel loss and a double walled construction with air gap/insulators between the walls to reduce the heat-induced evaporative loss of fuels in the fuel tank. The foam and/or mesh is made of various shapes and sizes and are inserted inside the tank to minimize the turbulence/slosh inside the tank. A cell size in the metallic foam and/or mesh is in the range of 2 mm to 5 mm to confine the fuel within the foam or mesh structure, and also the cell size is applicable to a wide range. An inter-cell distance is in the range of 3 mm-6 mm, and also the concept is applicable to a wide range of inter-cell distance.</p> |
