The world is facing declining liquid fuel reserves at a time when energy demand is exploding. As the supply decreases and costs rise, everyone will be forced to adopt the alternative energy resources. In order to achieve a secure and stable energy supply that does not cause environmental damage, renewable energy sources must be explored and promising technologies should be developed. Considering various gaseous fuels, Brown’s gas produced by the electrolysis process has the high potential for cost effective and emission aspects. It is identified as the one of the best partial alternate gaseous fuel to be enriched with intake air in a spark ignition engine or compression ignition engine. The present investigation involves the usage of Brown’s gas in SI engines. The experiment was carried out in a 100 cc single cylinder air cooled engine at 1500 rpm for various loads. The performance characteristics such as Brake thermal efficiency and Specific fuel consumption and emission characteristics such as Carbon monoxide (CO), Unburnt hydrocarbon (UBHC), Smoke (BSN) and Oxides of Nitrogen (NOx) were studied. The results are compared and found that the Brown’s gas enriched operation gives better results when compared with conventional engine operation.
