    The intake manifold for supplying air-fuel mixture from a single source to a plurality of cylinders of an internal combustion engine employs individual pipes all having the same cross sectional area but having different non-circular cross sectional contours. Where less fuel is needed at low engine speed and power output, the bottom half of each intake pipe is formed with a smaller internal radius of curvature than the top half. Where more fuel is needed at low engine speed and power output, the bottom half of each pipe is formed with a larger internal radius of curvature than the top half. The purpose is to better equalize the distribution of fuel to the cylinders under low speed and low power operation of the engine, without affecting fuel distribution at higher engine speeds.

    This invention relates to mechanical engineering, in particular to internal combustion engines.
    Internal combustion engines are known, which comprise cylinders and an intake manifold, equipped with a mixing-preparation device and having a distribution chamber for connecting the first and second patrols of the non-circular through passage, the sections of which are square with the same LI, to the first and second cylinders.
    However, these engines have poor technical and economic performance due to the uneven distribution of the air-fuel mixture in the cylinders.
    The purpose of the invention is to improve the uniform distribution of the mixture. The goal is achieved by the fact that in an internal combustion engine, comprising cylinders and an intake manifold, equipped with a mixing device and having
    distribution chamber and for connecting the latter to the first and second cylinders of the first and second nozzles of a non-circular flow section, the areas of which are the same, the nozzle sections are made asymmetrical relative to the horizontal plane, and the first nozzle has a flow area in the lower part
    to at the top, and the second pipe has in its lower part a flow area of smaller area than at the top. .
    Figure 1 shows the proposed internal combustion engine; on
    15 figure 2 - inlet pipe, top view; on fig.Z - section aa in figure 2; in fig. -mixer preparation engine, cut; figure 5 - intake manifold; on
    20 of FIG. 6 is a section BB in FIG.
    In the four-cylinder internal combustion engine (figure 1) contains cylinders 1 and an intake manifold, equipped with a mixing preparation device 2 and having a distribution chamber 3 connected to the cylinders using a pair of first branch pipes 5 and a pair of second branch pipes 6 and 7 of C 2) non-circular passage section. The flow sections of the nozzles -7 are asymmetrical in shape relative to the horizontal plane and all have the same area C of FIG. 3). At the same time, the first nozzles A and 5 have in the lower part a flow area of a larger area than in the upper part, and the second nozzles 6 and 7 have a flow area in the lower part of the smaller area than in the upper part.
    A mixing preparation device (Fig. (Formed by a carburettor, in the housing 8 of which a float chamber 9 is made, connected to the rapper 10 of the main metering system, and a mixing chamber 11, the output of which is communicated with the distribution chamber 3-
    The operation of the internal engine is as follows.
    When the engine is operating, the air passing through the mixing preparation device 2 carries the fuel flowing out of the atomizer 10 and mixes with it, forming a fuel-air mixture entering the distribution chamber 3Fuel flow, especially at low speeds, EXIT the openings of the atomizer 10 at an angle to the direction (air flow (indicated by arrows, in connection with i-ieM), the passage in the axial direction enters the distribution chamber 3 with an offset from its axis. To ensure uniform distribution of fuels In the engine cylinders, the first nozzles and 5 have a larger flow area in the lower part than in the upper part, since the fuel flow shifts in the distribution chamber 3 to the side adjacent to the second nozzle 6 and 7, whose flow sections in the lower part have a smaller value, At the same time, the nozzles -7 are made with a decrease in the size of the lower suit of the flow area one relative to the other from left to right and, therefore, have an increase in the size of the upper part of the flow area in the same sequence. We catch
    compensation of the axial displacement of fuel relative to the axis of the distribution chamber 3 is ensured and an even distribution of the air-fuel mixture over all engine cylinders is achieved.
    At the intake manifold (FIG. 5, the distribution chamber 12 is in communication with one first nozzle 13 and with one second nozzle I. Nozzle 13 (FIG. 6 has a lower section in the lower part than in the upper part and nozzle And in the lower part less than at the top. This achieves a uniform distribution of the air-fuel mixture in the cylinders to which the mixture enters through pipes 13 and I.
    This embodiment of the internal combustion engine provides an improvement in the uniform distribution of the mixture in the cylinders of the engine.
