Abstract: The article presents the test results of a one-cylinder, four-stroke diesel engine operating with neat jet fuel JP-8 and its various blends J5, J10, J20 and J30 with rapeseed oil. Load characteristics were taken at engine speed of n = 2000 min-1 which corresponds to maximum forgue mode. The air mass and fuel mass consumption along with CO, NO2, NOx, CH emissions and smoke of the exhaust were measured at engine load gradually increased up to maximum of 0,45 MPa. Engine performance parameters, fuel consumption per hour Bd, brake specific fuel consumption be and emissions of the exhaust with neat jet fuel JP-8 and its blends J5, J10, J20, J30 with rapeseed oil were analysed and campared for various engine loads and fuel blends used in these experiments. Analysis of the data optained shows that the engine operated most efficiently with minimum brake specific fuel consumption when running with the highest 30 vol % concentration rapeseed oil in JP-8 fuel blend (J30) at the highest load of 0,45 MPa. Whereas at idling mode the lowest fuel consumption was measured for neat jet fuel JP-8. The lowest emission of carbon oxide (CO) was measured when operating with the highest concentration blend J30, which contained 30% of rape-seed oil. Maximum NOx emissions (2801 ppm) also were measured for the maximum engine torque mode (0.45 MPa) when running with blend J30. The amount of NOx produced from com-bustion of blend J30 was 45.2% higher than that measured when running with neat (100%) JP-8 fuel at the same test conditions. Maximum CH emissions (710 ppm) and maximum smoke (11.9%) were also obtained when fuelling it with fuel blend J30 torque at maximum engine mode
