AB - 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. Highly  viscous honne oil can be reduced by blending it with diesel fuel. A direct  injection diesel engine typically used in agricultural sector was operated on  neat diesel and a blend of 50% honne oil with 50% diesel fuel (H50). Injector  opening pressure was changed to study the performance, emission and  combustion characteristics. It was observed that increasing the injector  opening pressure with H50 from the rated injector opening pressure (200 bar)  increased the brake thermal efficiency and reduced CO, HC, and smoke opacity  emissions. However, NOx emission was increased. With H50, ignition delay  decreased as injector opening pressure increased. Improved premixed heat  release rate were observed with H50 when the injector opening pressure was  advanced. The best injector opening pressure was 240 bar for H50 based on  brake thermal efficiency and emissions.
