Abstract

Diesel engines are used widely as they have lower fuel consumption and higher thermal efficiency in transportation sector. However, the emitted high NOx, CO and soot emissions have led researchers to search different alternative fuels. At this point, diesel fuels emulsions help to reduce exhaust emissions. In this study, the effects of diesel fuel emulsions containing 5% (E5) and 10% (E10) water on engine performance an exhaust emissions has been investigated. Mono ethylene glycol was used as an auxiliary emulsifier in the preparation of the emulsion. Use of the mono ethylene glycol reduced the subsidence rate of the E5 and E10 about 34.5% and 47.1% respectively. The experiments were conducted at full load condition and at 2500, 3250 and 4000 rpm engine speeds. Engine torque and power increased according to diesel fuel between 2400 and 3600 engine speed range when emulsified fuels were used. But significant reductions were observed after that engine speed range. It was observed that the nitrogenoxide (NOx) emission reduced 5.42% and 11.01% with using E5 and E10 fuel respectively according to diesel fuel at 2500 rpm. Also the soot emissions reduced 12.39% and 22.97% with using E5 and E10.
