Abstract

Alcohols are suitable substitutes for diesel engines. Higher-chain alcohols (methanol and ethanol), as opposed to lower-chain alcohols (methanol and ethanol), have a bright future in diesel engines. 1 - Pentanol, a higher-chain alcohol that can be produced from biomass, when compared to lower alcohols, 1-pentanol has better fuel characteristics. It can be blended with diesel to lessen pollution levels and demand on diesel fuel. The effects of exhaust gas recirculation (EGR) and the addition of 1-Pentanol on the performance and emissions of a direct injection diesel engine were investigated in this study. Fuel blends of (D100, D90Pen10, and D85Pen15) were created for experimental use work by adding 1-pentanol (10% and 15% by volume) to diesel. Engine tests were conducted at two engine loads (4 and 8 N.m) with a maximum and minimum engine speed to evaluate engine characteristics (2100 rpm and 3000 rpm) and EGR ratio (0%,5%,10%,15% and 20%). The results of the study showed that the addition the 1-pentanol leads to increases in the brake specific fuel consumption, decrease in brake thermal efficiency at (PEN15) and increases in exhaust gas temperature at maximum speed but the addition of 1-pentanol has a positive impact on NOX emissions and a negative impact on CO and UHC emissions. When using the EGR ratio, the results indicate that, brake specific fuel consumption increases and brake thermal efficiency decreases with increased EGR ratio while exhaust gas temperature and NOX emissions decreases, UHC and CO emissions increases with increased EGR ratio.
