An Experimental Investigation on Characteristics of a Diesel Engine with Decanol as an Additive using Corn oil Biodiesel

Abstract

Diminution of natural resources combined with the disturbing increment of contamination level is the main threat to utilize diesel in a naturally beneficent way. Research done till now focused upon the usage of lower alcohols and fewer data is available on higher alcohol mix in corn oil biodiesel. The present examination explores the impact of utilizing a ternary blend of diesel, biodiesel, and decanol as an additive in DI diesel engine. Tests were performed using decanol blended with biodiesel and diesel. The concentration of decanol mixing were 10%, 20%, 30% by volume while the diesel concentration was kept 50% all through. The research revealed brake thermal efficiency increases and brake specific fuel consumption decreases with increase in the concentration of decanol. BTE values for pure diesel, P100, D50P50, D50P40DC10, D50P30DC20, D50P20DC30 was observed as 32.16%,26.94%,28.55%,30.54%,30.68%,and 31.65% at full load. BSFC of ternary blend D50P20D30 was 20.58% and 12.90% less than P100 and D50P50. With the expansion of decanol content in the ternary mix, heat release rate is observed to be increased though the combined heat release rate is seen to be diminished during the end period of ignition. NOx emission was 1868 PPM, 1837 PPM, 1818 PPM and 1809 PPM for D50P50 and for 10%, 20% and 30% of decanol in the ternary blend. Therefore, the current examination prescribes 30% mix of decanol, biodiesel 20% and diesel 50% to improve engine performance and emission without any changes in the CI engine.
