The article presents the experimental test results of diesel engine efficiency operating on diesel fuel and tire pyrolysis oil blends. The aim of the work was to study the performance efficiency and emissions of a diesel engine fuelled with blends of diesel fuel (DF) and tire pyrolysis oil (TPO) at a constant engine speed and various load modes. For experimental research diesel engine "ORUVA F1L 511" was used. Diesel fuel and its blends TPO10 and TPO20 with tire pyrolysis oil were used for the research. During the test, the engine's hourly fuel consumption, volumetric air consumption, engine torque, emissions and smoke opacity were measured. In the studies, it was found that the highest brake specific fuel consumption was obtained when the engine was running on a fuel blend TPO20 of diesel and tire pyrolysis oil. At full load, TPO10 and TPO20 fuel blends resulted in 3.6 % and 4% lower engine brake thermal efficiency compared to the diesel engine, respectively. In the same mode, using a blend of diesel fuel and tire pyrolysis oil TPO10, the engine generated the highest total emissions of nitrogen oxides. At full load, the highest carbon monoxide CO emissions were obtained with the TPO20 fuel blend (745 ppm), and the lowest with diesel fuel (646 ppm). When the engine was operating at full load, the TPO20 fuel blend, generated 25.5 % less smoke opacity than the diesel fuelled engine.
