Performance, Combustion, and Emission Characteristics of Diesel Engine Fuelled with Waste Cooking Oil Biodiesel/Diesel Blends with Iron Oxide Nanoparticles

摘要

In the present research work, WCO biodiesel with iron oxide nanoparticle samples was considered for DI diesel engine, and its impacts on engine efficiency, combustion, and exhaust gas (emission) characteristics were studied. In this investigation the biodiesel is obtained from WCO by transesterification procedure. The experimental tests were conducted in a CI engine using WCO biodiesel with iron oxide nanoparticles. Engine trials were conducted for all the blends (B20WCOME and B20WCOMEINP75) and the obtained results were compared with diesel. All the tests regarding this work are carried out in a CI engine (diesel engine) at (1500 RPM) constant speed. The biofuel is obtained from WCO and commercially available iron oxide nanoparticles (INP) is used in the present experimental work. INP is added to biodiesel in proportions of 50, 75, and 100 ppm using an Ultrasonicator. The results obtained upon experimentation clearly show that the BTE increases marginally (14.285%) for iron oxide nanoparticles (for 75 ppm) blended WCOME while BSEC decreases (26%) when compared to other blends. The emission levels of oxides of nitrogen (4.87%), carbon oxide (16%), and unburnt hydrocarbons (10%) are marginally decreased as compared to diesel for 75 ppm concentration. From the present experimental work, the blending of iron oxide nanoparticles in WCOME produces most promising results in the CI engine performance with marginal drop in the harmful exhaust gases from CI engines.
