Performance, emission and combustion characteristics of direct injection diesel engine running on calophyllum inophyllum linn oil (honne oil)

Abstract: The present work examines the use of a non-edible vegetable oil namely honne oil, a new possible source of alternative fuel for diesel engine. A Direct Injection (DI) diesel engine typically used in agricultural sector was operated on Neat Diesel (ND) and neat honne oil (H100). At maximum load, with H100, brake thermal efficiency and NOx emission decreased where as emissions like CO, HC, smoke opacity increased. With H100, peak cylinder pressure and maximum rate of pressure rise decreased compared to ND. With H100, occurrence of peak pressure is away from top dead center compared to ND. With H100, ignition delay and combustion duration increased compared to ND.
