Abstract: The article presents experimental test results of a single-cylinder, air-cooled, DI diesel engine F1L511 operating on the normal (class 2) diesel fuel (DF), rapeseed oil (RO) and its 10vol%, 20vol% and 30vol% blends with aviation-turbine fuel F-34. The purpose of the research was to analyse the effects of using various rapeseed oil and jet fuel RO-10, RO-20, and RO-30 blends on brake specific fuel consumption, combustion, brake thermal efficiency, and emissions of the exhaust. The test results of engine operation on rapeseed oil and F-34fuel blends are compared with the respective parameters of a straight diesel running at full (100%) engine load and speed of 2000 rpm. The maximum NOx emission was obtained with the fully (100%) loaded engine running with 70% rapeseed oil and 30% jet fuel F-34 mixture. It was 12% bigger than the NOx emissions produced from the combustion of pure rapeseed oil. However, the amount of NOx was 0.5% lower than that produced by a straight diesel. Minimal carbon monoxide (CO) emissions obtained with the engine running with 70% rapeseed oil and 30% jet fuel mixture. Minimum smokiness of the exhausts obtained when running with rapeseed oil, - smokiness increased with the increased amount of jet fuel in the fuel blend. The changes in dynamic viscosity versus temperature were determined for the tested rapeseed oil and jet fuel blends. Research was conducted at different temperatures of 15⁰C, 20⁰C, 40⁰C, and 60⁰C. It was found that the kinematic viscosity of rapeseed oil and jet fuel mixtures decreases with increasing temperature and depends on the amount of jet fuel added to rapeseed oil
