Experimental Studies of Emissions in a CI Engine Blended with Refined Sunflower Oil


The present study analyzes emissions, by using different blends of diesel and Refined Sunflower oil (RSF) on Kirloskar Direct Injection 4-stroke Diesel engine, single cylinder air-cooled, 4.4 kW, constant speed at 1500 rpm, compression ratio 17.5:1, Methyl Esters of refined sunflower oil (BRS) was transesterified with sodium meth oxide before blending with diesel. The main objective of this study is to measure the NOx , CO, HC, and Exhaust temperature by varying the Injection pressure and the load. The experiments were conducted with various blends of diesel (BRS10, BRS30, and BRS40) at different pressures (180 bar, 210 bar, & 240 bar) and at different loads (0%, 25%, 50%, 75%, 100%). A 3–hole nozzle was used to inject the fuel. The Emission results were studied using AVL gas analyzer. The results show that there is an increase in CO, marginal increase in NOx and decrease in HC.
