dc.description.abstractThere is an increasing interest in India to search for suitable alternative fuels that are environmental friendly. Environmental concerns and limited amount of petroleum resources have caused interests in the development of alternative fuels for internal combustion (IC) Engines. As an alternative, biodegradable, renewable and sulphur free biodiesel is receiving increasing attention. The use of biodiesel is rapidly expanding around the world, making it imperative to fully understand the impacts of biodiesel on the diesel engine combustion process and pollutant formation. Biodiesel is known as the mono-alkyl-esters of long chain fatty acids derived from renewable feedstock, such as, vegetable oils or animal’s fats, for use in compression ignition engines. Therefore, in this study, different parameters for the optimization of biodiesel production were investigated in the first phase, while in the next phase of the study performance test of a diesel engine with neat diesel fuel and biodiesel mixtures was carried out. Biodiesel was made by the well known transesterification process. Waste cottonseed oil was selected for biodiesel production. The transesterification results showed that with the variation of catalyst, methanol, variation of biodiesel production was realized. A maximum of 76% biodiesel was produced with 20% methanol in presence of 1.0% KOH. The engine experimental results showed that among three different blends of biodiesel (B10, B15 and B20), B10 blend of biodiesel has the highest performance characteristic value of brake power, brake thermal efficiency lowest value of brake specific fuel consumption and exhaust gas temperature. The experimental result also showed that the exhaust emissions including carbon monoxide (CO), hydrocarbons (HC) and smoke emissions were reduced for all biodiesel mixtures and hydrocarbon (HC) and NOx emissions of B10 blend is lowest among all the three blends of biodiesel there is a slight increase in the carbon monoxide (CO) emission for the B10 blend as compared to B15 and B10. However, a slight increase in oxides of nitrogen (NOx) emission was experienced for biodiesel mixtures.en
