Modelling and Simulation of Gasoline Engine at Different Load Conditions using Oxyhydrogen Blend

The demand for fossil fuels is increasing regularly; therefore Researchers are facing the challenge of finding promising alternative fuels such as hydrogen, oxyhydrogen, alcohol, biodiesel fuels etc. Some of the adverse effects of the current fuel technology prevailing in internal combustion engines are poor air quality index, increased accumulation of greenhouse gases in the environment. The aim of present research was to generate the oxyhydrogen gas through the process of electrolysis and send the homogeneous mixture of gasoline and oxyhydrogen into the four cylinder four stroke spark ignition engine and then analyse emission and performance parameters. Oxyhydrogen gas was manipulated as a secondary fuel in spark ignited1298 cc engine. Results obtained conclude that by using oxyhydrogen and gasoline mixture the r.p.m increased by 9%, fuel consumption decreased by 10.80%, brake power increased by 8.61%, indicated power increased by 12.63% whereas indicated and brake specific fuel consumption decreased by 21.18% and 18.17% respectively, also the emission of hydrocarbon decreased by 8.25% and carbon monoxide decreased by 6.05%. The drawback of this research setup was the increase in frictional losses due to high heat generation which accompany the reduction in mechanical efficiency by 4.31%. Oxyhydrogen generator and supplying system can be made compatible to the engine without any major modification which approaches towards better results.
