Abstract: This article discusses possibility to apply additives based on linseed oil aiming at improvement of antiwear properties of diesel fuel. Diesel fuel in engine, together with its main function – production of heat upon combustion, acts as lubricant of precision couplings of engine fuel system. Design peculiarities, specifications and operation conditions of fuel system reveal that diesel fuels do not satisfy the requirements to lubrication of precision couplings of injection nozzles due to poor lubricating and antiwear properties. In order to improve lubricating and antiwear properties of diesel fuels, they are compounded with additives. In Russia imported additives manufactured by various companies are used, not all consumer requirements are met and such additives are very expensive. Compositions and production technologies are not disclosed, though, it is known that such additives are based on plant products (acids of vegetable oils, etc.). Low lubricating properties of Russian fuels, high cost and low efficiency of imported additives require for development of efficient Russian additives aimed at improvement of antiwear properties of diesel fuel and increase in lifetime of engine fuel system. Available information about studies of physicochemical and antiwear properties of composite fuels does not reliably estimate possibility to blend fuel with additives based on vegetable oils. This work is aimed at comparative studies of physicochemical and antiwear properties of commercial diesel fuel and diesel fuel blended with additive based on linseed oil (TLOA) intended for improvement of lifetime of precision couplings of engine fuel systems. The influence of fuel blending with TLOA on fuel antiwear properties (density, kinematic viscosity, surface tension, coefficient of friction, wear) has been estimated. It has been concluded that it is possible to use TLOA to improve lifetime of injection nozzles. It has been revealed that upon diesel fuel blending with TLOA in amount of 5 wt %, the density and viscosity of composite fuel slightly increase but remain in the range of recommendations for summer diesel fuel.
