    one
    The invention relates to mgshshio. the structure, in particular, for internal combustion engines, namely, for their launch.
    There are known internal combustion engines that contain an intake air duct, installed in a nominal air preheater, equipped with a fuel inlet and outlet, a fuel evaporator and its igniter vapor and connected to a source of fuel supply through an electrically controlled valve and fuel supply channel, fuel injection system into cylinders, equipped with nozzles and a main line to drain excess fuel into the tank, and a main line supplying fuel to the fuel supply source l3.
    However, the launch of known engines is not effective enough.
    The purpose of the invention is to increase the efficiency of starting the internal combustion engine.
    This goal is achieved by the fact that the fuel supply source is supplied by the fuel chamber. And is connected to the supply line through the chamber inlet channel which communicates with the air intake duct
    by means of an aperture and provided with a body alternately blocking the aperture and inlet kangsha, respectively, for communication with the air duct and supply line.
    The fuel chamber can be equipped with an exhaust channel, located at a level above the inlet channel and connected to the drain line of excess fuel into the tank, and the alternate shut-off organ can be made with the possibility of an exhaust kaial simultaneously with the inlet overlap.
    The inlet and exhaust channels can be connected to each other by a bypass channel.
    The alternating cover body can be electrically operated.
    Electric: the actuator of the alternate shut-off organ is interlocked with the electrically controlled valve of the preheater.

    [1]
    The body of the fuel supply source can be made of two parts, in the first of which there are fuel, inlet and exhaust channels, an opening for its communication with the air pipeline, a sequential shut-off organ, and in the second its electric drive, which can be made in the form of an electromagnet, wound sleep. FIG. 1 shows the scheme of a VENTILATED internal combustion engine; in fig. 2 - preheater, cross section; in fig. 3 - the source of fuel supply with the organ alternately shifted in the first position, transverse. incision; in fig. 4 - the same, in the second position. . / The proposed divider 1 is a compression ignition internal combustion engine. It contains an air intake duct 2, an air preheater 3 installed in it, equipped with fuel inlet 4 and outlet 5, an evaporator 6 of fuel and an igniter 7 of its vapors and connected to source 8 of the fuel supply through an electrically controlled valve and 9. connecting channel 10, fuel injection system into cylinders equipped with nozzles 11 and highway 12 draining excess fuel into tank 13, and line 14 supplying fuel to source 8 of fuel from nozzles 11. In addition, the engine 1 sleeps by exhaust pipe 15, combined with the turbine 16 of the turbocharger, the compressor 17 of which is connected to the air intake pipe 2. The fuel injection system into the cylinders is also equipped with a high-pressure pump 18, driven by engine 1 and feed fuel from tank 13 to the injectors 11. The air revolver 3 consists of a hollow body 19 provided with a thread for mounting it into the inlet pipe 2. In the case 19 a central tubular piece 20 is installed, forming fuel inlet 4 and outlet 5 at its ends and provided with a seat 21 against which electrically controlled valve 9 is pressed , made in the form of a ball 22 for cutting off the flow of fuel and the core element 23. The ball 22 is pressed against the seat 21 by means of a core element 23, the thermal expansion coefficient of which is different from this parameter of the part 20. The output 5 of the part 20 is opened with a pipe chaty udlinitel.24. The parts 20 are equipped with an evaporator 6 of the incoming fuel and an igniter 7 of its vapor, connected to terminal 25 and extension 24. The fuel supply source 8 is located above the preheater 3, as a result of which the fuel can flow to it by gravity, equipped with a fuel chamber 26 and connected to the supply line 14 through the inlet channel 27 of the chamber 26, which is connected to the inlet air pipe 2 by means of the aperture 28 and is provided with a body 29 in turn. blocking the opening 28 and the inlet channel 27. The chamber 26 is also provided with an exhaust channel 30 located at a level above the inlet channel 27 and connected to the main line 12 to drain excess fuel into the tank 13, with the alternating valve body 29 being able to lock the exhaust channel 30 simultaneously with the overlap of the inlet channel 27, and these channels communicate with each other by means of a bypass coupling 31. In addition, the organ 29 is provided with an electric actuator that is interlocked with the electrically controlled valve 9 of the preheater 3 and It is made in the form of an electromagnet 32, equipped with a winding 33. On the support 34 of the electromagnet 32 a compression coil spring 35 is installed, pressing the organ. 29. The housing 36 of the fuel supply source 8 is made of a composite of two parts, in the first of which fuels are located “a chamber. 26, inlet 27 and outlet 30, an opening 28 for communicating with the air duct 2, a shut-off member 29, and an electric actuator in the second. When the engine 1 is running, the engine 29 is alternately shut off at the first position / and the fuel flows from the injectors 11 through line 14 to the fuel chamber 26 of the fuel supply source 8 through its intake port 27. The fuel level in the chamber 26 rises until it reaches the lower edge of the exhaust channel 30. After that, the excess fuel flows through the exhaust channel 30. Via a discharge line 12 to the tank 13. It should be noted that the fuel chamber 26 is under atmospheric pressure. When engine 1 is inoperative, organ 29 is also in the first position. To facilitate the start of cold engine 1, it is necessary to use preheater 3 air. For this on. electromagnet 32, evaporator 6 and igniter 7 supply voltage. As a result, the organ 29, compressing the spring 35, moves to the second position. Thus, it closes the inlet 27 and outlet 30 channels and releases the opening 28. As a result, the fuel enters through the channel 10 to the fuel inlet 4 of the preheater 3. When the part 20 and the core element 23 are heated, they expand, but not uniformly, because they have different coefficients of thermal expansion . Due to the thermal inertia of the preheater 3, a certain period of time is required for the ball 22 to move away from the saddle 21. The fuel will pass into the gap between the saddle 21 and the ball 22. When fuel enters output 5, it evaporates, resulting in fuel leaves the outlet 5 in the form of vapor, which ignites the igniter 7. After the formation of the flame, the engine 1 is started to start. The heated air entering the engine 1 through the intake pipe 2 makes it easier to start. At the beginning of the start, the turbocharger does not work, but as the engine 1 speed increases, compressor 17 begins to supply air to pipeline 2 under pressure. Since chamber 26 communicates with pipe 2 through aperture 28, the pressure in it is the same as in pipe 2. The fuel enters the preheater 3 until fuel remains in chamber 26 and the gap between the seat 21 and the ball 22 remains. After removal. the tension of the organ 29 is returned to the first position, and the ball 22 is pressed against the saddle 21. The chamber 21 is clearly filled with fuel, as described above. Thus, in accordance with the present invention, the efficiency of starting the internal combustion engine is improved. Claim 1.
