Variations in oxygenated blend composition to meet energy and combustion characteristics very similar to the diesel fuel

By the method of data collation, research into changes in life histories (ignition delay plus time of combustion) of the compounded fuel droplets (diesel fuel–biodiesel fuel (RME)–bioethanol), as well as diesel engine D-144 brake specific fuel consumption rates was performed and obtained results being compared to diesel fuel by an analogous manner. An optimum composition of the multi-component blend B30 + 7.5E demonstrating specific fuel consumption rates and droplet combustion characteristics very similar to diesel fuel was derived. In comparison to B30, a newly derived combustible blend demonstrated fairly improved emissions of exhaust gases. For low load mode: smoke opacity (−10%), NO X (−2%), CO (−20%), and HC (−12.5%). For average load mode: smoke opacity (−10%), NO X (−2%), CO (−22%), and HC (−14.5%). For high load mode: smoke opacity (−18%), NO X (−2%), CO (−22%), and HC (−18%).
