A comparative study ofMesua ferreaL. based hybrid fuel with diesel fuel and biodiesel

Abstract

The study presents preparation of a Mesua ferrea L. seed-oil-based emulsion hybrid fuel system by blending with alcohols (ethanol and butan-2-ol) in which butan-2-ol was employed as a surfactant. The study also deals with the investigation of the effect on fuel properties of the hybrid fuel due to the variation in surfactant amount and analysis of the prepared hybrid fuel system by 1 H nuclear magnetic resonance ( 1 H NMR). The experimental results show that the properties of the hybrid fuels were comparable to that of diesel and biodiesel.

Performance, combustion and emission characteristics of a direct injection VCR CI engine using a Jatropha curcas oil microemulsion: a comparative assessment with JCO B100, JCO B20 and petrodiesel

“…2,[4][5][6] In sight of these difficulties, microemulsication technique has been regaining importance as an economically viable and 'green' approach for liquid biofuel production from vegetable oils. 5,[7][8][9][10][11] Especially, in the recent 2-3 years several research articles dealing with production, characterization and application of hybrid diesel fuels by microemulsication method were reported. 7,8,10,[12][13][14] The advantages of microemulsication approach over the chemical routes (transesterication, hydrocracking, hydroprocessing etc.)…”

“…Their method makes use of the naturally occurring monoglyceride, diglyceride and free fatty acids (or esters in case of pretreated oils) components present in these low grade oils as the surfactants to produce thermodynamically stable, isotropically clear microemulsion systems (Windsor Type IV) with anhydrous ethanol as dispersed phase and 1-butanol or 2-butanol as the co-surfactant. [8][9][10] Keeping in view the importance of microemulsion systems like MHBF as renewable and low cost fuel alternative to reduce CI engine exhaust and maintain the engine efficiency, an investigation of the recently introduced MHBF was found necessary to conrm its potential utility as a fuel. Accordingly, the CI engine performance, combustion and emission analysis of Jatropha curcas oil (JCO) based MHBF were studied in a single cylinder direct injection CI engine and reported herewith.…”
