Abstract: Abstract In the current investigation, fuel blend combination (FBC) of spirulina microalgae biodiesel (SMAB), diesel, ethanol, and methanol is prepared and assessed. Engine performance and spray attributes of FBC were investigated through Diesel-RK Software (DRS) at different engine loads using FBC0, FBC1, FBC2, FBC3, FBC4, FBC5, and FBC6. The viscosity of SMAB decreased with the addition of alcohol. Increasing percentage of SMAB from 0 to 40% in the FBC increases the spray characteristics by 11.9%. Performance of engine was enhanced by adding ethanol and menthol to SMAB and diesel combinations. Brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) were 1.7% higher and 6.6% lower for FBC6 blend compared to FBC0 (diesel fuel). Increase in percentage of SMAB, ethanol, and methanol in hybrid fuels has shown a decrease in smoke emissions, NOX emissions by 41.3 and 43% at various engine loads.
