An Experimental and ANNs Study of the Effects of Safflower Oil Biodiesel on Engine Performance and Exhaust Emissions in a CI Engine

Abstract

In this study, the experimental results obtained concerning engine performances and exhaust emissions of a diesel engine fueled with diesel fuel–biodiesel (produced from safflower oil) blends compared with diesel fuel in laboratory tests. In the results of tests, engine torque, engine power and specific fuel consumption as performance values of test fuels were commentated. Values of engine torque and engine power from biodiesel were lower than diesel fuel fuel as average 26% amount, and values of specific fuel consumption from biodiesel were higher than diesel fuel as average 41.5% amount. CO emission values of biodiesel decreased as average 74% amount according to diesel fuel. With using biodiesel, increased as average 2.45 fold amount for CO2 emissions, as average 1.3 fold amount for NO emissions, , and decreased as average 87% amount for HC emissions with compared to diesel fuel.

Keywords

• Biodiesel from safflower oil,engine performance,exhaust emissions,diesel engine.
