The fuel pump (6) pumps the bio-fuel out of the tank (2) and along the fuel lines through the coarse fuel filter (4), the fine fuel filter (7) and the reducing valve (10) into the evaporator (11), where the heater (13) vaporizes the fuel. After that the fuel vapors mix with air inside the air/fuel mix intake (12). The temperature sensors (15) measure the mix' temperature both before and after the heater (11) and signal the electronic regulator (14), which, in its turn, depending on the sensor data, set the temperature for the heater (13). Thus, the electronic regulator (14) makes timely and accurate adjustments depending on the diesel engine's operational mode. As the heating of the air/fuel mix depends on the diesel engine's RPM and the evaporated fuel volume, the designed system makes timely and accurate adjustments to the air/fuel mix temperature in the air/fuel mix intake based on the engine's operational mode. Thus, we can sustain the required volatile fuel evaporation rate, as well as, the mix composition for any mode of the diesel engine work, therefore, increasing the engine's efficiency.

To increase the homogeneity of the fuel emulsion we used paired clockwise/counterclockwise-oriented agitator blades. Each blade pair is positioned against the inlet chamber and the respective plunger pair. The system is designed to mix emulsion with the bio-fuel content of 0 to 100 % and diesel fuel (DF) content of 100 to 0 %, respectively. The components ratio error doesn't exceed 5%. The output of the designed system makes it possible to mix the necessary amount of fuel emulsion of the required composition and homogeneity for any of the engine's operating modes. For the diesel engine to use volatile bio-fuels we designed an original supply system (Fig. 3) [18,19]. The system operates as follows.

The tested tractor was modified accordingly. To make the diesel-fuel/alcohol emulsion we installed a mechanically driven agitator into the manufacturer-installed fuel tank. On the right side of the tractor cabin we installed an additional diesel-fuel-only 10 liter tank. The installation of additional fuel lines and a coarse fuel filter was easy enough. The tractor's basic technical parameters ale listed in Table 1 below. The testing was done as follows: Fig. 3.Diesel engine volatile-bio-fuel supply system [18]: 1,2 - primary- and bio-fuel tanks;3 – fuel lines; 4 - coarse fuel filters; 5,6 – fuel pumps; The start and the following warming up of the diesel engine was diesel fuel only.
