Abstract

In the current study, the physicochemical, engine performance, and exhaust emission of different ternary fuel blends containing waste fish oil (WFO) biodiesel, bioethanol, and petro-diesel have been investigated. WFO Biodiesel was prepared from waste fish oil via transesterification method. Different physiochemical properties including the kinematic viscosity, density, flash point, pour point, cloud point, and heat value have been measured for different fuel blends and compared with the neat petro-diesel. The performance and exhaust emission of engine have been also studied using different fuel blends using a single-cylinder diesel engine in full load condition at 1800 rpm. It was found that the engine torque, engine power, and thermal efficiency of the ternary fuel blends was reduced by 2.45%, 9.25%, 2.35% averagely in comparison with the neat petro-diesel, respectively. The average break specific fuel consumption was also increased by 10.44% compared to the neat petro-diesel. The emission of carbon monoxide (CO), carbon dioxide (CO), unburned hydrocarbons (UHC), and nitrogen oxides (NO) was also measured. It was also found that the utilization of ternary fuel blends results in a considerable reduction in CO and UHC emission by 50.55% and 43.87% on average compared to the neat petro-diesel, respectively. The emission of NO was also increased by 28.25% on average compared to the neat petro-diesel. It was also found that the NO emission can be adjusted by tuning the WFO biodiesel and bioethanol contents of the ternary fuel blends.

摘要

在当前的研究中，已经对含有废鱼油（WFO）生物柴油、生物乙醇和石化柴油的不同三元燃料混合物的物理化学性质、发动机性能和废气排放进行了研究。WFO生物柴油是通过酯交换法由废鱼油制备而成的。已经测量了不同燃料混合物的各种物理化学性质，包括运动粘度、密度、闪点、倾点、浊点和热值，并与纯石化柴油进行了比较。还使用单缸柴油发动机在1800转/分钟的满负荷条件下，对不同燃料混合物的发动机性能和废气排放进行了研究。结果发现，与纯石化柴油相比，三元燃料混合物的发动机扭矩、发动机功率和热效率平均分别降低了2.45%、9.25%、2.35%。平均制动比油耗也比纯石化柴油增加了10.44%。还测量了一氧化碳（CO）、二氧化碳（CO₂）、未燃烧碳氢化合物（UHC）和氮氧化物（NO）的排放。还发现，与纯石化柴油相比，使用三元燃料混合物可使CO和UHC排放平均分别大幅降低50.55%和43.87%。与纯石化柴油相比，NO排放平均也增加了28.25%。还发现，可以通过调整三元燃料混合物中WFO生物柴油和生物乙醇的含量来调节NO排放。
