Thermodynamic Analysis of Compression Ignition Engine Fueled with Blends of Processed Railway Waste Engine Oil 2020-28-0443
Depletion of fossil fuel and the explosion in energy demand led the researchers to find the alternative of conventional fuels for internal combustion engines. The tendency of oil price has increased consecutively and especially India has a deficient amount of fossil fuel. Focusing on the scope of a particular field, processed waste engine oil (WEO) of the railway is blended with diesel and investigated on the compression ignition engine. WEO derived from railway loco was processed through successive chemical processes to attain optimum fuel characteristics. The processed WEO is blended with diesel by volume 10, 15, 20, 25, and 30%. The performance indicators of the engine such as BP, TFC, BSFC, and brake thermal efficiency have been investigated using different WEO blends. Apart from engine performance, the thermal analysis of engine in terms of EGT, total heat supplied, heat equivalent to BP, heat carried by cooling water, heat carried by exhaust gas, and unaccounted heat also carried out to determine the optimum blending. The results obtained from a thermodynamic analysis of Diesel engine are variant in nature for different blends. However, the major conclusions advocate that the blending of processed WEO up to 20 % offers optimum engine performance.
