Popis: Recently, the utilization and research of biodiesel has become increasingly popular due to its reduced emissions, lower cost, and potential for achieving energy independence. A promising application of biodiesel is in diesel engines, where it can be used as a substitute for traditional petroleum-based diesel fuel. Camelina sativa is an oil seed crop with prospective uses in biodiesel extraction due to its high crop harvest in a year, good net energy ratio, the considerable oil content in its seed, and lower oil extraction expenses. Biodiesel derived from camelina sativa L. is prepared via transesterification. In this study, the prepared biodiesel is blended with diesel at various proportions and is used in an engine to investigate its combustion performance and emission characteristics. From the results, it is evident that the CMB 20 blend (20% of camelina biodiesel and 80% of diesel) shows the better performance among all of the blends used. The brake thermal efficiency of CMB 20 is 23.45%, its specific fuel consumption is 0.355 kW/kg hr, and it also produced less emissions when compared to other blends.
