Abstract
the conventional fossil fuels for internal combustion engines will be available for few years only, due to tremendous increase in the vehicular population. Moreover, these fuels cause serious environmental problems by emitting harmful gases into the atmosphere at higher rates. Commonly pollutants released by engines are CO, Unburnt hydrocarbon, NOx, smoke and particulate matter. At present, alternative fuels like methyl ester of vegetable oil, alcohols etc. are in the line to replace the fossil fuels for IC engines. In the present study and experimental investigation were carried out with waste cooking oil as an alternative fuel in a compression ignition (CI) engine. The problem associated with vegetable oil are high viscosity , lowered volatility and high reactivity, but at the same time their higher cetane no, lower sulphur content , inherent oxygen concentration are the desirable properties to use as fuel in compression ignition engines. The process of transesterification of vegetables oil with methyl alcohol provides a significant reduction in viscosity, thereby enhancing the physical properties of vegetable oil. The present paper show a study carried to investigate the combustion, performance and emission characteristics of waste cooked oil methyl ester with diesel fuel on a single cylinder, four stroke, direct injection and water cooled diesel engine. The results of blends of biodiesel and diesel for different measurements such as BSFC, BSEC, BTE, Mechanical efficiency, EGT, A/F ratios, volumetric efficiency, CO, CO2, HC, and NOx & smoke opacity are compared with that of pure diesel. Biodiesel can be blended with diesel in any volume percentage. The Properties of waste cooked biodiesel are determined and found that its properties are nearer to diesel fuel.
