Experimental Investigation on CI Engine Using Waste Transformer Oil Methyl Esters as Bio Diesel

Modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. Day by day the demand for non renewable energy sources increases. Automobile leads to demand for petroleum based fuels. The present investigation oil is taken the waste transformer oil .The transformer oil is produced from wax-free naphthenic oils. Transformer oils are an important class of insulating oils. They act as a heat transfer medium in the transformer. After certain period of time of operation in the transformer the oil is thrown out in the form of waste. So the suitability of using waste transformer oil as alternative fuel for compression ignition engine and comparing its performance parameters with conventional diesel. Experimental investigation is carried out on 4 strokes –twin cylinder water cooled diesel engine. Preparing blends of transformer oil with diesel like T10, T20, T30, and T40 and comparing its performance parameters with conventional diesel. Among these blends selecting optimum blend and adding ignition improver in a different proportions and finding optimum blend. Then comparing performance parameters of the optimum blend with conventional diesel fuel. Here use Isopropyl alcohol is as ignition improver for optimum blend. Based on the earlier finding the current experimental investigation investigated the possibility of using waste transformer oil is a diesel substitute. The objective of the present research was to explore technical feasibility of waste transformer oil in direct injection C.I engine without any substantial modifications in the engine design
