Abstract

The utility model is aimed at reducing the toxicity of exhaust gases of an internal combustion engine. The specified technical result is achieved by the fact that the power supply system of the internal combustion engine further comprises a mixing chamber with partitions facilitating intensive mixing of the emulsion in a shorter period of time. Inside the mixing chamber are located mixers, driven by an external power source, and a sensor for measuring the quality of the emulsion obtained. 1 cpf, 1 ill.

Description

The utility model relates to mechanical engineering, power systems for internal combustion engines and can be used in the operation of engines to improve environmental performance.

The essence of the utility model: in order to increase the uniformity of the water-fuel emulsion, the power supply system of the internal combustion engine additionally contains a mixing chamber with partitions that facilitate intensive mixing of the emulsion. Inside the mixing chamber are located mixers, driven by an external power source, and a sensor for measuring the quality of the emulsion obtained.

A known power system for an internal combustion engine (see USSR patent No. 1420222, class F02M 25/02, publ. 30.08.88), comprising a tank, a fuel supply line to the high pressure fuel pump, connected to the fuel tank through a float device, a drain pipe excess fuel from the fuel pump, an emulsion chamber mounted in the fuel tank on its bottom and made in the form of a hydraulic ultrasonic whistle.

A disadvantage of the known system is the large capacity of the tank, requiring multiple passage of the emulsion along the circuit to achieve the required quality of the emulsion, which increases the time required to prepare the working mixture.

The technical result of the utility model is to reduce the toxicity of exhaust gases by increasing the uniformity of the fuel-oil emulsion in a shorter period of time.

Figure 1 shows a diagram of a power system for an internal combustion engine.

The power supply system contains a fuel tank 1, to which a fuel supply line 3 is connected to a high pressure fuel pump 4 installed in the engine 5 through a float device 2. The output end 6 of the pipeline 7 for draining excess fuel from the fuel pump 4 is connected to the end opening 8 of the emulsion chamber 9 The latter is made in the form of a hydraulic ultrasonic whistle, equipped with an ejection tube 10, connecting its side wall 11 with the internal cavity 12 of the tank 1. The emulsion chamber 9 is placed in the fuel tank 1 on it about the bottom 13. In the highway 3 of the fuel supply is installed a mixing chamber 14 (Fig.2.) with partitions 17, inside of which there are mixers 15 and a sensor 16 for measuring the quality of the resulting emulsion.

The power supply system of an internal combustion engine operates as follows.

The fuel tank 1 is filled with fuel and water in the required proportions. Starting the engine 5 and warming it up is carried out on clean fuel, which is ensured by the intake of fuel using the float device 2. From the tank, fuel through the line 3 enters the mixing chamber 14 with partitions 17, then to the high pressure fuel pump 4 and then to engine 5. B the mixing chamber 14 is intensive mixing of the emulsion coming from the tank 1 with mixers 15, which are driven from an external power source as the required quality of the working mixture, the composition of which is controlled sensor 16 measuring quality. The excess fuel through the drain pipe 7 through the end hole 8 enters the emulsion chamber 9. Since this chamber is made in the form of a hydraulic ultrasonic whistle, in it the kinetic energy of the moving fuel is converted into vibrational energy. Under the action of the vacuum created in the emulsion chamber 9, into it through the ejection tube 10 from the inner cavity 12 of the tank 1

water comes in. When mixing, fuel and water in the form of an emulsion flow from the emulsion chamber 9 into the internal cavity 12. The quality of the emulsion is also ensured by its repeated passage through the circuit: float device 2 — line 3 — mixing chamber 14 — high pressure fuel pump 4 — pipeline 7 — emulsion chamber 9.

When the engine is stopped, after some time the emulsion is stratified into fuel and water.
