本文研究了一台单缸、四冲程、水冷、直喷(DI)、自然吸气式压燃(CI)发动机的燃烧、性能和排放参数，该发动机在恒速(1500 )下的额定功率输出为3.7kW 。将不同负荷条件(25%、50%、75%、100%)下的微生物掺烧柴油比(BYY)与柴油在CR17.5：1下进行了比较，结果表明，与柴油相比，最佳掺烧比例为B20%。试验结果表明，该车的制动热效率降低了0.98%，排气温度降低了1.7%，碳氢化合物(HC)降低了16.3%，一氧化碳(CO)降低了3.6%，NOX排放降低了6.8%，烟度排放降低了12.35%。其次，在发动机转速恒定的满载条件下，与柴油(B0%)相比，螺旋桨终止率(B20%)比柴油(B0%)的比油耗增加了5.2%，CO2排放量增加了2.8%。
The present work encompasses combustion, performance, and emission parameters of experimental investigations of a single cylinder, four stroke, water cooled, direct injection (DI), naturally aspirated compression ignition (CI) engine with a rated power output of 3.7 kW at constant engine speed (1500 rpm) using diesel and different blends of microalgaespirulina. The microalgaespirulinablend of ratio with diesel (BYY) where YY indicates blending percentage (0%, 20%, 40%, 60%, 80%, and 100% volume basis with diesel respectively) with different engine loading condition (25%, 50%, 75% and 100%) were compared with diesel at CR17.5:1. The output illustrates that the most optimum value is B20% when compared with diesel. The result depicts firstly that there is a reduction in brake thermal efficiency by 0.98%, exhaust gas temperature by 1.7%, hydrocarbon (HC) by 16.3%, carbon monoxide (CO) by 3.6%, NOXemission by of 6.8%, and smoke emission by 12.35% respectively. Secondly, there is an increase in specific fuel consumption by up to 5.2% and CO2emission by 2.8% forspirulinablend ratio (B20%) as compared to diesel (B0%) at full load condition engine with constant engine speed.
