Esterified Papaya Oil and Flamboyant Oil as a Fuel on Single Cylinder Diesel Engine

Abstract

The future demand, increase in the price and environmental issues of fossil fuels necessitated the search of renewable alternate called biodiesel which reduces the dependence of fossil fuel import from other countries. The present research investigation outlines a detailed vision on the performance parameters and the exhaust characteristics of the methyl esters of papaya oil (POME) and flamboyant oil (FOME) and its blends on water cooled diesel engine comprising single cylinder running at 1500 rpm. The collected seeds are processed and found to contain oil percentage of 37% and 35% and they are esterified in a reactor to enhance its properties. From the result it is concluded that at maximum load, the blend B25 of papaya biodiesel accounted in better brake thermal efficiency than that of diesel with relatively less exhaust emission, such that the specific fuel consumption, brake thermal efficiency, exhaust gas temperature, smoke density, carbon monoxide emission, hydrocarbon emission and nitrous oxide emission are 0.27 kg/kW-hr, 31.46 %, 318°C, 49.02 Hsu, 0.095 %, 55 ppm and 988 ppm respectively.
