This design allows you to improve the environmental, economic and power performance of engines without significant changes to the power systems and without the use of emulsifiers by obtaining a fuel-water mixture immediately before injection and supplying it to the internal combustion engine with standard nozzles, as well as eliminating the possibility of freezing water in the system for receiving and supplying fuel -water mixture during its operation, by draining water from the system at ambient temperatures below 1 ° C.

The proposed device is illustrated in the drawing, which shows a diagram of a system for receiving and supplying a fuel-water mixture in an internal combustion engine.

The proposed system consists of a tank 1 for fuel, a tank 2 for water, a fuel supply line 3 including a pump 4, a filter 5, a return line 6 and a fuel pressure regulator 7, a water supply line 8 including a pump 9, a filter 10, a return line 11 and a water pressure regulator 12, an electronic control system for electromagnetic valves, including at least an electronic control unit 21, an ambient temperature sensor 22 and a water level sensor 23 in the water tank 2, a fuel rail 13 with fuel-water mixture injection nozzles 14 and is integrated its channel 15 water supply, and the channel 15 water supply on one side is connected to the highway 8 water supply, on the other hand is connected to the atmosphere, is located inside the fuel rail 13 and has holes 16 opposite each nozzle 14 of the injection of the fuel-water mixture, and the internal cavity 17 of the fuel rail 13 is connected to the fuel supply line 3, the water supply channel 15 is made through the entire fuel rail 13, the first solenoid valve 18 is installed on it from the side of the fuel rail 13, and 13 n from the side of the fuel rail it has a second solenoid valve 19 located at the top of the system, the water tank 2 has a third solenoid valve 20 located at the bottom of the system, the solenoid valves 18, 19 and 20 are connected in such a way that, provided that there is water in the water tank 2 when the engine is not running and the ambient temperature is below 1 ° C, all three solenoid valves 18, 19 and 20 open, and when the engine is running, provided that there is water in the water tank 2, only the first solenoid valve 18 is open, in otherwise, all three solenoid valves 18, 19 and 20 are closed.

The proposed system works as follows. The electromagnetic valves are controlled by an electronic control system of electromagnetic valves, based on the signals received from the ambient temperature sensor 22, the water level sensor 23 in the water tank 2 and the engine operation signal, for example, coming from the ignition key. When the engine is running, subject to the presence of water in the water tank 2, only the first solenoid valve 18 is open, and the second solenoid valve 19 and the third solenoid valve 20 are closed. In this case, the fuel is supplied by the pump 4 from the fuel tank 1 through the fuel supply line 3 through the filter 5 to the internal cavity 17 of the fuel rail 13. The pressure in the fuel supply line 3 is changed by the fuel pressure regulator 7 depending on the engine operating conditions or is kept constant. excess fuel is returned to the tank 1 for fuel on the return line 6. Water is supplied by the pump 9 from the tank 2 for water through the water supply line 8 through the filter 10 to the water supply channel 15. The pressure in the water supply line 8 is changed by the water pressure regulator 12 depending on the engine operating conditions or is kept constant, while the excess water is returned to the water tank 2 along the return line 11. Due to the pressure difference, water from the water supply channel 15 enters through openings 16 into the nozzles 14 of the injection of the fuel-water mixture, is mechanically mixed with the fuel filling the internal cavity 17 of the fuel rail 13, forming a fuel-water mixture, which is injected into the stream through the nozzles 14 of the injection of the fuel-water mixture ozduha entering the internal combustion engine cylinders.

Under the condition of the presence of water in the water tank 2 when the engine is idle and the ambient temperature is below 1 ° C, for example, during long-term storage, all three solenoid valves 18, 19 and 20 open, with the third solenoid valve 20, the water tank 2 connects to the environment or, for example, to a tank for storing water that is not susceptible to damage caused by freezing of water, and through the second electromagnetic valve 19, the water supply channel 15 and the water supply line 8 are connected atmosphere to equalize the pressure and thus is more complete and rapid discharge of water from the system.

In other cases, all three solenoid valves 18, 19 and 20 are closed. In this case, the water supply channel 15 is disconnected from the atmosphere through the second electromagnetic valve 19 and disconnected from the water supply line 8 through the first electromagnetic valve 18. In this case, only fuel entering the internal cavity 17 of the fuel is supplied through the nozzles 14 of the injection of the fuel-water mixture into the internal combustion engine ramps 13 on the fuel supply line 3 from the fuel tank 1.
