To explore the effect of hybrid fuels containing microalgae, ethanol, methanol and diesel fuel (base fuel) were blends on combustion, performance and emission characteristics and compare with base fuel. The hybrid fuels were calculated using a single-cylinder, four-stroke, naturally aspirated engine, water-cooled, direct injection, diesel engine was used for the experiments under 20%, 50%, 75%, 100% load and simulated by using a thermodynamic engine simulation tool software. The results show that engine brake torque (EBT) of hybrid fuel (ethanol) emulsions were found to be high and exhaust gas temperature to be low compared with that of base fuel. Hybrid fuel (methanol) emulsions helps to increase the cylinder pressure. With the hybrid fuels blend, the ignition delay period and combustion duration of hybrid fuel blends is increased. With the addition of spirulina microalgae, the ignition delay period of spirulina microalgae-diesel blend fuel is shortened. Engine emission results indicated that spirulina microalgae emulsions fuel reduces the specific particulate matter (PM), soot and smoke emissions except nitrogen oxides (NO_X) emissions but carbon dioxide (CO2) emission to be higher compared with base fuel.

为了探讨含微藻的混合燃料的影响，将乙醇，甲醇和柴油燃料（基础燃料）混合在一起，对燃烧，性能和排放特性进行了比较，并与基础燃料进行了比较。使用单缸，四冲程，自然吸气发动机，水冷，直喷，柴油发动机计算混合燃料，在20％，50％，75％，100％负载下进行实验，并通过热力发动机仿真工具软件。结果表明，与基础燃料相比，混合燃料（乙醇）乳液的发动机制动扭矩（EBT）高，排气温度低。混合燃料（甲醇）乳液有助于提高气缸压力。使用混合燃料混合物，混合燃料混合物的点火延迟时间和燃烧持续时间增加。添加螺旋藻微藻后，螺旋藻微藻-柴油混合燃料的点火延迟时间缩短。发动机排放结果表明，螺旋藻微藻乳液燃料可减少特定颗粒物（PM），烟尘和烟气排放，但氮氧化物（NO_X）排放量，但二氧化碳（CO2）排放量比基础燃料要高。
