Abstract

The present work examines the use of a non-edible vegetable oil namely honne oil, a new possible alternative fuel for diesel engine. The use of neat honne oil (H100) in diesel engine has not been reported in the literature. A direct injection (DI) diesel engine typically used in agricultural sector was operated on neat diesel (ND) and H100. Injector opening pressure (IOP) was changed to study the performance, emission and combustion characteristics. It was observed that increasing the IOP with H100 from the rated injector opening pressure (200 bars) increased the brake thermal efficiency and reduced CO, HC and smoke opacity emissions. However, NOx emission was increased. With H100, ignition delay decreased as injector opening pressure increased. Improved premixed heat release rate was observed with H100 when the injector opening pressure is advanced. The best IOP is 240 bars with H100 based on brake thermal efficiency.
