In current days, fuel economy of automobile become major concerns for not only consumers but also automobile products. The addition of hydrogen in lean burn combustion is one of the way to increase fuel economy. By the way, for supply hydrogen to automobile engine, we need to hydrogen source. On-board fuel reforming can be a solution for hydrogen supply in automobile system. To produce hydrogen with fuel reformer, we need oxidizer. Current fuel reformer need to additional water tank and air compressor. So we use exhaust gas, due to there are enough steam and oxygen in engine exhaust gas and we have experience of exhaust gas reuse, similar to EGR system. In this work, we found the possibility of fuel reforming with using exhaust gas by calculation of thermodynamic equilibrium. After calculation of fuel reforming we test our fuel reforming system with iso-octane with monolith coated CGO-Pt catalyst. Fuel was fully converted by hydrogen and synthetic gas during changing exhaust gas ratio, temperature, composition of exhaust gas and GHSV of reactant. Maximum fuel conversion efficiency was 78% at certain operating condition.
