LOW HYDROCARBON EMISSION FUEL TANK WITH INTERNAL COMPONENTS

摘要

A low permeation fuel tank formed with a first half (12) and a second half (14) includes a hydrocarbon barrier and a fuel system module (16). The hydrocarbon barrier reduces the emission of hydrocarbons from the fuel tank. Minimization of discontinuities in the hydrocarbon barrier is achieved by positioning the fuel system module (16) within the fuel tank. The fuel system module (16) includes a pre-formed sheet (46) to provide flexible and rigid support to the fuel tank. In addition, the fuel system module (16) may include fuel system components (44), structural enhancements of the fuel tank and/or functional features (48) of the fuel tank to minimize production of holes or other discontinuities in the hydrocarbon barrier.
