Recent Advances in Reducing Fuel Permeability and Leakage into the Environment from Automotive Fuel Systems

Leakage and permeability through fuel systems is an ongoing problem that both environmentalists and automakers face, but with the application of multi-layer plastic material technology and new manufacturing processes of internalizing components, partial zero emissions vehicles (PZEV) can be achieved. The legislative requirements that must be met for the future fuel systems regarding their permeation and leakage performance are discussed. Recent efforts on how the automotive industry is responding to meet those challenges are also presented.
