Diethyl Ether as an Oxygenated Additive for Fossil Diesel/Vegetable Oil Blends: Evaluation of Performance and Emission Quality of Triple Blends on a Diesel Engine

摘要: The aim of this work is to analyze the effect using diethyl ether (DEE) as an oxygenated additive straight vegetable oils (SVOs) in triple blends with fossil diesel, be used current compression ignition (C.I.) engines, order implement process replacing fuels others a renewable nature. use DEE considered taking into account favorable properties for blending SVO and such its very low kinematic viscosity, high oxygen content, autoignition temperature, broad flammability limits (it works cold start aid engines), values cloud pour point. Therefore, can solvent reduce viscosity improve flow properties. Besides, renewable, since it easily obtained from bioethanol, which produced biomass through dehydration process. evaluated mixtures were castor oil, inedible, sunflower standard reference waste cooking oil. In meet European petrodiesel EN 590, study more relevant rheological biofuels DEE/vegetable oil double has been performed. incorporation diesel these gives rise diesel/DEE/vegetable blends, exhibited suitable able operate conventional engines. These have tested engine, operating electricity generator. efficiency, consumption smoke emissions engine measured. results reveal that substitution up 40% by volume achieved, independently employed. Moreover, significant reduction emission levels pollutants better also all tested.
