Abstract
The current numerical study examines the effect of using beef oil methyl ester (BOME) blends with diesel fuel on diesel engine characteristics. The engine powered by diesel fuel and three different volumetric blends of BOME biodiesel (10%, 20%, and 30%). The simulation program Diesel-RK has been used. The results obtained showed an increase in the brake specific fuel consumption (BSFC) as a result of replacing BOME with diesel. The brake thermal efficiency (BTE) decreased slightly by 1.5384%, 3.0855% and 2.3597% for the use of 10%, 20% and 30% BOME respectively due to difference in heating content of BOME blends. The exhaust temperature dropped for all BOME blends. Slight increase in NOx emissions by 4.1227%, 9.6836%, and 13.7105% correspond to 10%, 20% and 30% of BOME respectively. Compared with diesel the bosh smoke number (BSN) decreased by 4.44619%, 11.846%, and 17.8947% for B10, B20, and B30 respectively. A little increase in CO2 emission. The findings of this investigation are compared with the results of other studies and reported an acceptable deviation.
