Abstract: Fossil fuels like as coal, petroleum, natural gas meets the world’s energy demand. They are depleting rapidly at the same time there combustion products are causing global problems such as acid rain, greenhouse effect, ozone layer depletion and pollution which is adversely impacting our environment and eventually total life on our planet. All researchers and engineers always struggling to produce a best suitable and reliable way for substitution of existing fossil fuels such as gasoline, diesel. Hydrogen gas has been considered as a best alternative to gasoline. The various investigators have completed their experiment by running various capacity engines on hydrogen. Most of such experimenter is successful in running IC engines on hydrogen without any big modification. There results and findings are available in the open literatures. However there is no consistency between the results of investigators and this is the big problem of these experiments. The hydrogen combustion increases thermal efficiency and its high velocity burning characteristic gives faster and smoother burning. The hydrogen also reduces critical pollution levels. Hydrogen combustion produces very clean exhaust due to its desirable characteristics. The hydrogen burning lowers HC, CO, CO2 and NOX levels from exhaust. As of now hydrogen combustion is dangerous due to back fire problems, but new developed technologies and science in fire arresters ensures us the backfire free operation of hydrogen operating engine and same time make it possible to control hydrogen supply precisely. In this paper the experimental analysis and result discussion is made on performance and emissions behavior of hydrogen-gasoline fuelled SI engine and its safe use.
