The automotive industry urgently requires advanced technology for fuel containment. It is being subjected to ever-tighter regulations to reduce emissions, and in the longer term, new sealing systems need to be developed for alternative fuels and their associated powertrains. Moreover, in their current configurations the potential adoption of fuel cells as a power source brings with it a massive increase in the sealed surface area where failure can lead to loss of stack integrity. This paper outlines the potential for mathematical modelling tools as the future method for designing and improving performance of fuel sealing systems in vehicles. One of the proposed tools will allow engineers to design the whole fuel system, select the fittings of appropriate types and sizes, and then estimate the total fuel leakage as new and over the life time for different models of vehicles. BHR already has stand-alone software to model fuel leakage and ageing of elastomer components, and sealing systems, and an integrated software package will shorten product development time and reduce physical testing costs. The use of computational analysis offers a highly cost effective way forward for assessing potential emission and/or limitations of proposed fuel connectors and system design, without having to make large numbers of fuel system prototypes tests. It provides design engineers with predictions of emissions during fuel system development, therefore enabled optimisation of new fuel systems. Component suppliers can also consider the effect of their connector design to the overall emissions. In the longer term, the software can be expanded to time based analysis. Alternative fuels from future 'clean' vehicles will expose their fuel systems to a variety of new fluids, including the by-products of electrochemical processes. Knowledge and techniques gained from related process and nuclear industries can be applied to the design of vehicle fuel system, with the aid of computational analysis tools.
