Bio-diesel as an alternative fuel for diesel engines—A review

Abstract: The present review aims to study the prospects and opportunities of introducing vegetable oils and their derivatives as fuel in diesel engines. In our country the ratio of diesel to gasoline fuel is 7:1, depicting a highly skewed situation. Thus, it is necessary to replace fossil diesel fuel by alternative fuels. Vegetable oils present a very promising scenario of functioning as alternative fuels to fossil diesel fuel. The properties of these oils can be compared favorably with the characteristics required for internal combustion engine fuels. Fuel-related properties are reviewed and compared with those of conventional diesel fuel. Peak pressure development, heat release rate analysis, and vibration analysis of the engine are discussed in relation with the use of bio-diesel and conventional diesel fuel. Optimization of alkali-catalyzed transesterification of Pungamia pinnata oil for the production of bio-diesel is discussed. Use of bio-diesel in a conventional diesel engine results in substantial reduction in unburned hydrocarbon (UBHC), carbon monoxide (CO), particulate matters (PM) emission and oxide of nitrogen. The suitability of injection timing for diesel engine operation with vegetable oils and its blends, environmental considerations are discussed. Teardown analysis of bio-diesel B20-operated vehicle are also discussed.

Production and analysis of bio-diesel from non-edible oils-A review

Abstract: Bio-diesel has become more attractive recently because of its environmental benefits and it is derived from renewable resources, bio degradable and non-toxic in nature. Several bio-diesel production methods have been developed, among which transesterification using alkali catalyst gives high level of conversion of triglycerides to their corresponding methyl ester in short reaction time. The process of transesterification is affected by the reaction condition, molar ratio of alcohol to oil, type of alcohol, type and amount of catalysts, reaction time and temperature, purity of reactants free fatty acids and water content of oils or fats. In this work, an attempt has been made on review of bio-diesel production, methods of analyzing, bio-diesel standard, resources available, process developed performance in internal combustion engines, teardown analysis of bio-diesel B20 operated vehicle, recommendation for development of bio-fuels, environmental considerations, economic aspects and advantages. The technical tools and process for monitoring the transesterification reaction like TLC, GC, HPLC, GPC, 1H NMR and NIR have also been summarized in this paper.

Production and wear characterisation of AA 6061 matrix titanium carbide particulate reinforced composite by enhanced stir casting method

Abstract: Metal matrix composite (MMC) focuses primarily on improved specific strength, high temperature and wear resistance application Aluminium matrix reinforced with titanium carbide (Al–TiC p ) has good potential The main challenge is to produce this composite in a cost effective way to meet the above requirements In this study Al–TiC p castings with different volume fraction of TiC were produced in an argon atmosphere by an enhanced stir casting method Specific strength of the composite has increased with higher % of TiC addition Dry sliding wear behaviour of AMC was analysed with the help of a pin on disc wear and friction monitor The present analyses reveal the improved specific strength as well as wear resistance

Study of structural and optical properties of cupric oxide nanoparticles

Abstract: In this study, cupric oxide (CuO) nanoparticles were synthesized via sonochemical method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. The spherical CuO nanoparticles were dispersed in sodium hexametaphosphate under sonication (25 kHz) to analyze the particle size distribution and UV absorption spectra. Using these absorption spectra, we further examined the CuO nanoparticle to explore the possibility of using them as a material for applications such as solar cell and textile production.
