The use of biofuel as a supplementary fuel may reduce environmental pollution, strengthen the agricultural economy, create job opportunities and reduce diesel requirements, thereby contributing to the conservation of a major commercial energy source. Methanol is one of the possible alternatives for the partial replacement of mineral diesel in diesel engines. The studies apply biofuel (methanol) blends on the engine exhaust emissions results were compared with the baseline (pure ultralow sulfur diesel fuel) case. Results showed that the CO emissions could be reduced by up to 33.33% for the 5 wt% methanol blend case, HC emissions could be reduced by up to 20.83%, NOx emissions could be reduced by up to 25.38%, smoke emissions could be reduced by up to 13.19%, CO2 emissions could be reduced by up to 16.13%, engine exhaust gas temperatures could be decreased by 5.56%; and O2 emission could be increased by 1.89%. Thus, biofuel (methanol) blends can be added to diesel fuel for reducing engine exhaust emissions. The engine exhaust emissions for biofuel (methanol) blends are lower than those for pure ultralow sulfur diesel fuel because of the presence of O2 in the molecular structure of the biofuel (methanol). Biofuel is increasingly replacing pure ultralow sulfur diesel fuel as a renewable and sustainable alternative for diesel engines.
