As we approach the next century, the scientists recognize that our supply of fossil fuel is limited. Hence, more efficient use of the fossil fuel are required. This paper give some possible use of new catalytic system that can produce the maximum benefits of fuel-treatment process which can give better combustion, maximum power with minimum noxious pollutants. The reformed fuel was obtained in the laboratory by special mixing process and the ignition study was conducted on the fuel. The ignition probability study is one of the methods used by researchers in United Kingdom to study the comparison of ignitability of fuels used in spark ignition engine. This preliminary study has been carried out, based on UK Emission Consortium Methods for High Tolerance EGR Combustion in the laboratory. The study has been carried out using fan-stirred bomb with various turbulent conditions. The study has shown that the reformed fuel-air has better ignition probability
