One of the types of motor biofuels for diesel engines is blended fuel obtained by mixing petroleum diesel and vegetable oils. One of these oils can be safflower oil produced from the seeds of Carthamnus tinctorius. The main physical, chemical, and calorific properties were studied for the safflower oil and for its blends with petroleum diesel oil. The results of bench dynamometer tests of D-243 diesel engine (four-stroke, four-cylinder, direct injection, compression ignition engine), running on safflower biodiesel blends, are presented. The proportions of safflower oil and diesel oil in the fuel blends were 20/80, 25/75, 33/67, and 50/50. Moreover, the blended fuel 50/50 was processed with 25 kHz ultrasonic emitting. When the diesel engine was running on blended fuel, brake power decreased by 1-4 percent, brake specific fuel consumption increased by 4-10 percent, while the exhaust smoke opacity was less by 10-40 percent compared to the engine operation on the petroleum diesel oil. The processing of the fuel blend 50/50 with ultrasonic allows improving engine power capacity, efficiency, and smoke opacity compared to the engine operation on unprocessed blended fuel.
