    The device is intended to introduce additional gas flows (air, exhaust gas, cracked gas) in the intake channel (39) of an internal combustion engine (11) wherein the mixture is compressed by means of slots (9, 10) facing each other in the wall of the intake channel downstream of the throttle valve (2) and extended in the peripheral direction of the intake channel (39) on a peripheral angle smaller than 180<o>, to which the additional gas is supplied by one of a plurality of inlet conduits (6, 7, 8, 14, 15, 19, 20); regulation member (5) is provided to regulate the additional gas flow supplied by those inlet conduits as a function of the vacuum prevailing in the intake channel (39). The slots (9, 10) are orientated so that none of them is traversed by a partition surface separating the intake channel (39) and formed by the displacement of the longitudinal axis of the throttle shaft (21) in parallel to the very surface along the longitudinal medial line of the intake channel (39). Such a device provides for a good preparation of the mixture and consequently an enhancement of the thermal efficiency of the internal combustion engine while enabling to lower the fuel consumption and the noxious gas content in the exhaust gas.

    The invention relates to mechanical engineering, in particular to a device for processing liquid fuel in an internal combustion engine with compression of the mixture.
    The purpose of the invention is to reduce the toxicity of exhaust gases.
    Figure 1 schematically shows the proposed device for processing liquid fuel in an internal combustion engine; figure 2 is a section aa in figure 1.
    A device for processing liquid fuel in an internal combustion engine 1 with compression of the mixture (Fig. 1) comprises a spacer 3 installed behind the carburetor and having an arcuate element 4, the edges of which form two diametrically located output windows 5 and 6 of slotted channels connected to a common channel 7, formed by carburetor 2 and a spacer and connected to the pipe 8 of the pipe 9 for supplying a gaseous medium. The pipeline 9 is equipped with a thermal reactor 10 and a regulating body made in the form of a rotary valve 1 1 and installed in the nozzle 8. The rotary valve 11 is placed on the roller 12, kinematically connected with the rotary drive roller 13 of the throttle valve 14 of the carburetor 2, and is made with the possibility of complete overlap the cross section when installing the thia of the cross section when the throttle valve 14 is set to the idle position and the passage section is fully open when the throttle valve 14 is set to the middle position x loads. The output windows 5 are symmetrical about the axis of rotation of the rotary drive roller 13 of the throttle valve 14 and are located behind the carburetor relative to the flow of the air-fuel mixture. The thermal reactor 10 has a reaction chamber 15 connected via a channel 16 to the flow part 17 of the exhaust pipe 30 18 of the engine 1. The walls of the thermal reactor 10 are coated with catalytic material, for example, vanadium, and a wire heating element 19 made of catalytic is installed in the reaction chamber 15 material, such as platinum, and is connected to a current source (not shown) by means of pins 20. As can be seen from Figure 2, the arcuate element 4 θ spacer 4 forms a curved channel 21 that tells the output of 5 but with a common channel 7.
    The device operates as follows.
    When the engine 1 is idling, the rotary and throttle valves 11 and 14 are in the closed position, and when the throttle valve 14 is set to the medium load position, the rotary valve 11 is set to the fully open passage section of the nozzle 8. Therefore, the gas flowing through the pipe 9 passes through a common channel 7 and goes to the exit window 6 of the slotted channel directly from the common channel 7, and to the exit window 5 - passing through the curved channel 21. If the throttle valve 1526586 is not fully opened, 14 of the carburetor 2, the air-fuel mixture formed in the latter passes through the formed crescent-shaped gaps between the throttle valve 14 and the carburetor 2, and the largest amount of condensed fuel is formed on the walls of the latter in the gap zone. With small openings of the throttle valve 14, the flow rate of the mixture is low, so that a small amount of fuel settles on the walls, and with an increase in engine load 1, the amount of condensed fuel increases. In this case, the gas flowing out of the outlet windows 5 and 6 acts on the condensed fuel, providing for its atomization, and this gas effect is carried out in the zones of the highest fuel condensation, i.e. in areas located at the farthest from the axis of rotation of the throttle, and the amount of gas acting on the mixture changes as the engine load increases, which is achieved by the maximum opening of the rotary valve 11 in the medium load mode. Gas entering the pipe 9 is taken from the flow part 17 of the exhaust pipe 18 through the channel 16 and enters the thermal reactor 10, in which the reaction chamber 15 in the exhaust gas under the influence of heat from the heating element 19 and in the presence of catalysts decomposes water into hydrogen and oxygen, so that the gas flowing out of the slotted channels provides, in addition to the dynamic effect on the fuel, also thermal, contributing to the homogenization of the mixture, and the gas formed in the thermal reactor 10, being a cracked phase, When mixed with the air-fuel mixture, during the combustion of the latter in engine 1, it reduces nitrogen oxides in the engine exhaust. At the same time, a uniform distribution of the mixture over the engine cylinders is achieved, and therefore the toxicity of the exhaust gases is reduced.

    average loads. The exit ports 5 and 6 are symmetrical about the axis of rotation of the rotary drive roller 13 of the throttle valve 14 and are located behind the carburetor relative to the flow of the air-fuel mixture. The thermal reactor 10 has a reaction chamber 15 connected via a channel 16 to a flow part 17 of the exhaust pipe 18 of the engine 1. The walls of the thermal reactor 10 are covered with a catalytic material, such as vanadium, and a wire heating element 19 is installed in the reaction chamber 15 , for example, platinum, and connected to a current source (not shown) with the help of pins 20. As can be seen from FIG. 2, the arcuate element 4 forms a curvilinear channel 21 in the spacer, informing the output window 5 with a common channel 7.
    The device works as follows.
    When the engine 1 is in idling mode, the rotary and throttle valves 11 and 14 are in the closed position, and when throttle valve 14 is set to the average loads position, the rotary valve 11 is set to the full opening of the bore section of the pipe 8. Therefore, the gas flowing through the pipeline 9, passes through the common channel 7 and goes to the output window 6 of the slotted channel directly from the common channel 7, and to the output window 5 - passes through the curvilinear channel 21. If the opening 51 is not fully open
    The choke valve 14 of the carburetor 2 forming the mixture in the air-fuel passes through the formed flow-through crescent gaps between the throttle valve 14 and the carburetor 2, and the largest amount of condensed fuel is formed on the walls of the latter in the gap zone. With small openings of the throttle valve 14, the flow rate of the mixture is small, so that a small amount of fuel is deposited on the walls, and as the engine load 1 increases, the amount of condensed fuel increases. At the same time, the gas flowing from the output windows 5 and 6 acts on the condensed fuel, ensuring its dispersion

    This gas exposure is carried out by a carburetor placed on the surface in areas of the most condensation of the fuel, i.e. in the zones located in the most distant from the axis of rotation of the throttle, and the amount of gas acting on the mixture changes with increasing engine load, which is achieved by maximal opening of the rotary damper 11 in the mode of medium loads. The gas entering the pipeline 9 is taken from the flow section 17 of the exhaust pipe 18 through the channel 16 and enters the thermal reactor 10, in the reaction chamber 15 of which in the exhaust gas under the influence of heat from the heating element 19 and in the presence of catalysts water is decomposed on hydrogen and oxygen, so that the gas flowing out of the slotted channels provides, besides the dynamic effect on the fuel, also thermal, which promotes the homogenization of the mixture, and the gas formed in the thermal reactor 10 is cracked when mixed with the air-fuel mixture during combustion of the latter in the engine 1, it reduces nitrogen oxides in the exhaust gases of the engine.
