When society is cognizant of depleting reserves of fossil fuels beside the deteriorating global climate, it is apparent that biodiesel promises to make a handsome contribution to the future energy demands of the domestic and industrial economies. Among different edible (crop based) and non-edible potential foliages of biodiesel (mono alkyl esters) castor is an esoteric potential of sustainable energy and promising substitute for crop-based biodiesel. The present work investigates the possibility of a novel fuel additive package synthesized from castor oil for agricultural diesel engines. The research challenge of fuelling diesel engines with crude castor oil in absolute package concerns its high viscosity. The mechanism of transesterification using lower or higher alcohols subsides the viscosity of crude castor oil to an acceptable range and other properties were evaluated using diesel as baseline fuel. In present investigation, castor oil methyl and ethyl esters (COME and COEE) were synthesized using both methanol and ethanol. The physical and chemical properties of COME and COEE were proximal and COME revealed a little higher viscosity than that of COEE. Low temperature operability (cloud point and pour point) of COEE were better than those of COME. Engine performance and exhaust emission characteristics were analysed using additive package to diesel such as COME20, COEE20 and absolute package of COME, COEE, with petroleum diesel being the standard fuel. Results inferred that COME yielded a little higher power than that of COEE and hazardous emissions of COEE being slightly lower than that of COME. The research work concludes that both COME and COEE can be used as an additive package (20%) to petroleum diesel in agricultural CI engines without any modification in engine hardware. However absolute package of COME and COEE to agricultural CI engines extends the research work to an aesthetical change in engine hardware facilitating preheat up to 60-1000C overcoming cold weather operability.
