This paper is concerned with the benefits of addition of 1-pentanol and benzyl alcohol, which are classified as aliphatic and aromatic type alcohols respectively based on the position of hydroxyl group, to a blend of Siarouba glauca and diesel (B20) in minor quantities. This was later tested under various load conditions to study the performance, emission, and combustion on a CRDI engine. Literature is cited to show that the poor performance of B20 can be enhanced substantially by the addition of 1-pentanol (P) and benzyl alcohol (Bn). Each sample of fuel was prepared by 5% concentration by volume addition of 1-pentanol and benzyl alcohol. The tests were conducted on a single-cylinder, four-stroke, and constant speed CRDI engine and compared with the results from which diesel was used as a fuel. Break thermal (BT) efficiency is found to be a considerable 9.08% and 5.5% more in 5%pentanol and 5% Benzyl Alcohol fuel blends respectively than that of diesel. While comparing brake specific fuel consumption (BSFC) it was found that diesel has a noticeable 24.32% more consumption rate than both the fuel types. The emission rate of CO was found to be 81.25% and 81.33% less with 5%pentanol and 5% Benzyl Alcohol fuel blends than that of diesel. Diesel also released .5714 and .2698 times more Hydrocarbon(HC) compared to 5%pentanol and 5% Benzyl Alcohol respectively. However, NOx emissions were higher in both 5%pentanol and 5% Benzyl Alcohol. These benefits are documented by comparing each fuel in different load conditions and are represented graphically.
