The article is devoted to the solution of the problem associated with the partial substitution of marketable mineral diesel fuel (DF) with mixed vegetable-mineral (MDF) engine fuel. The bio-component of MDF is vegetable oil, for example, Camelina seed oil. A design option of a dual-fuel feeding system has been proposed, the main component of which is a mixing and metering unit for vegetable oil and mineral diesel fuel which allows electric metering units controlled by an electronic control unit (ECU) to respond to signals from diesel load-speed sensors (crankshaft speed, injector rack position (fuel injection pump)) and temperature gauge of camelina oil, to ensure the feed of mixed diesel fuel with components of different content. The use of mixed diesel fuel based on vegetable oil, containing for example 50 % of mineral commercial fuel and 50 % of camelina oil, makes it possible with a slight decrease in the effective power (not more than 6 %) and some increase in the specific effective consumption of mixed fuel (up to 14 %) to save 50 % of fuel of petroleum origin, as well as to reduce the smoke opacity of exhaust gases by 17–20 % and reduce the content of carbon oxide by 35–40 % compared with the work of a diesel engine on commercial mineral diesel fuel.
