Experimental Analysis of the Performance of Hevea brasilensis and Jatropha curcas Oils as Biodiesel


Keywords: , , , , ,

A sure source of energy at a realistic cost for the continuation and development of the adapted life style of the inhabitants of the industrialized and the non oil producing developing world has become the concern of many scientists, energy researchers and governments because of the impending gap, which appears inevitable in the not too distant time, between the eventual demise of the conventional fossil fuels as sources of energy and the emergence of long term replacement. Biodiesel is an alternative fuel made from renewable biological sources such as edible and non-edible oil. The non-edible vegetable oil of the seeds of Jatropha curcas, Hevea brasilensis, etc, has the potential of providing viable alternative to petroleum diesel fuel. The Jatropha curcas and Hevea brasilensis oil were produced by first collecting and de – husking the seeds, then drying and grinding of the seeds before extracting the oil using a screw press machine. A Yoshita R175AN four stroke single cylinder diesel engine with declared speed of 2600 rpm and rated power of 4.85kw unmodified was used for the experiment by measuring its speed when loaded with 30kg load and when not loaded using a Tachometer. The exhaust gases were similarly analyzed using SV – 5Q Automobile Exhaust Gas Analyzer. From the results, comparing the different speeds and powers generated by the engine using the different fuels, it is clearly seen that the power and speed generated by 100% transesterified Jatropha curcas oil and 100% transesterified Hevea brasilensis oil is higher than that of 100% Petroleum diesel. In a percentage of 20% petroleum diesel and 80% biodiesel, Hevea brasilensis biodiesel produces more speed and power compared to Jatropha curcas biodiesel.
