Experimental Investigation of Using Eucalyptus Oil and Diesel Fuel Blends in Kirloskar TV1 Direct Injection Diesel Engine

Abstract

The aim of this study is to partial replacement of diesel fuel with eucalyptus oil and experimentally determines their effects on the engine performance, combustion and exhaust emissions such as brake specific energy consumption (BSEC), brake thermal efficiency (BTE), heat release rate, cylinder pressure and emissions such as smoke density, carbonmonoxide (CO), unburned hydrocarbon (UBHC) and oxides of nitrogen (NOx). For this purpose, five different blends containing 10, 20, 30, 40 & 50% of eucalyptus oil with diesel fuel were prepared in volume basis and tested in naturally aspirated direct injection kirloskar TV1 diesel engine with constant speed of 1500 rpm at varying load conditions. Results indicated that the brake thermal efficiency is increased about 6.2% for 60:40 DF/EOF blend (blend has 60% of diesel and 40% of eucalyptus oil) as compared to standard diesel fuel (DF) operations. Further the results showed that at full load condition, 60:40 DF/ EOF blend have 16.7%, 25% and 15.15% reduction of smoke, CO and UBHC respectively as compared to standard DF. NOx emission is slightly reduced about 0.97% for 60:40 DF/ EOF blend as compared to DF. The heat release rate and cylinder pressures are increased positively.
