Sažetak

This study evaluated diesel engine performance and emission properties when fueled with an already-produced kariya oil biodiesel (KOB) and KOB blends. This intends to explore KOB blends as a supplement in diesel engines. A hand-held exhaust gas analyzer was used to determine the gas emitted. In contrast, the brake power and exhaust gas temperature were determined using a Schenck W230 Eddy Current dynamometer and a thermometer respectively during the operation of the diesel engine fueled with KOB. In contrast with standard petroleum-based diesel, the findings show that using KOB in diesel engines reduces CO and HC but increases NOx emitted due to its oxygenating property that aids fuel combustion. Also, with an increase in biodiesel blends, the fuel consumption increased, while the brake power and exhaust gas temperature decreased due to lower calorific value, higher viscosity, higher volumetric fuel per engine stroke, and the oxygen content dominating over lower calorific value for better combustion. From the study, both KOB B10 and B30 blends were considered optimally appropriate fuel supplements in a diesel engine.
