Working Characteristics of a C.I. Engine Fuelled with Oxygenates as Additives in Jatropha Biodiesel

Abstract:

An experimental investigation is conducted for studying the effect of the oxygenates blended with Jatropha biodiesel in a single cylinder Direct Injection diesel engine by using AVL 444 Di-gas analyzer for measuring level of pollutants at engine exhaust and AVL 437 smoke meter for measuring smoke opacity. Two oxygenated additives namely Ethylene Glycol (C₂H₆O₂) and Propylene Glycol (C₃H₈O₂) are added equally to neat biodiesel at geometric sequence (1, 2 and 4 %) forming the blends EGPG1 (Biodiesel + 0.5 % Ethylene Glycol + 0.5 % Propylene Glycol), EGPG2 (Biodiesel + 1 % Ethylene Glycol + 1 % Propylene Glycol) and EGPG4 (Biodiesel + 2 % Ethylene Glycol + 2 % Propylene Glycol). This paper highlights the effect of two oxygenates added as additive in biodiesel, that affecting the performance and emission characteristics of the engine. Marginal improvement in the performance of the engine and reduced level of pollutant such as Carbon monoxide (CO) and Smoke opacity for the test fuels are observed with slight increase in NO ( Nitrogen oxide ) and Unburned Hydro carbon (UHC) emission.
