    Unequal fuel concentrations in air-fuel mixtures delivered by a downdraft carburetor to branched intake pipes leading to engine cylinders has been traced to asymmetrical fuel delivery into the venturi passage in the carburetor. To equalize the fuel concentrations carried in the branched pipes, an inclined wall is provided in the distribution chamber that receives the air-fuel mixture from the carburetor. The inclination of the wall directs a greater quantity of air-fuel mixture into the branched pipe which would otherwise receive a leaner mixture because of the asymmetrical distribution of fuel from the venturi passage.

    FIELD: engine engineering | and “stiles to the devices for supplying the top-of-the-air mixture to the multi-cylinder internal combustion engine .b
    Devices are known for supplying a fuel-in-head mixture to a multi-cylinder engine of internal combustion, a downstream carburetor with a downstream flow carburetor, a junction box for receiving a fuel-its shower mixture, a branch pipe located on one side of the distribution chamber for feeding the mixture to at least one cylinder of an engine; b a second branch pipe located on the other side of the distribution chamber for supplying fuel & air mixture to at least another cylinder of the engine the body, the top jet nozzle 30 placed in the inlet pipe transversely in the plane of location of the branch valves and in the outlet, the first branch pipe so that most of the fuel is 25
    Combustion
    to the first of the branched pipes, and the distribution chamber has a wall that extends from the carburetor and is located opposite the inlet pipe (1}.
    A disadvantage of the known kautor lies in the fact that, because it is supplied to the air flow, the code through the diffuser is unevenly distributed because the diffuser has a vertical axis, and the top / tail valve enters the diffuser at a right angle to this axis.
    The invention is to increase efficiency.
    This goal is achieved by the fact that the wall of the distribution chamber is inclined to the axis of the inlet pipe in the direction of the second branch pipe in order to increase the concentration of the top Man to the second branch pipe.
    4th g. 1 shows the carburetor assembly; in fig. 2 shows section A-A in FIG. one.

    The carburetor I contains a pipe nozzle 2 with {Iffuzsfom 3. The fuel jet 4 enters the diffuser 3 at an angle, the fuel jet 4 receives fuel from the float (Zhy chamber 5. The carburetor I is installed on the suction pipe 6 and forms the distribution chamber 7, from which branch in the opposite direction: the two Tiiy6 lines 8 and 9, respectively. The distribution chamber 7 has a wall 10, which is inclined to the axis of the inlet Tpy6t of line 2 by 1 ° 30. The slope of the wall 1O is that it is higher and closer to the branch pipe 9, lower and closer to oi. The branch pipe 8, i.e., the wall is inclined towards the pipe 8, the inlet pipe 2 also has a throttle valve 11. The carburetor works as follows: Air passes through diffuser 3, and the liquid fuel passes through the nozzle 4, mixed with air The fuel / fuel mixture passes through throttle valve II, enters the suction pipe 6 and the distribution chamber 7, and flows in opposite directions along branch pipes 8 and 9, respectively. The flow of the fuel-air mixture collides with the inclined wall 10 (the slope is made sufficiently steep to direct a large amount of the fuel-air mixture into the branch pipe 8, compared to the amount of fuel that goes into the branch pipe 9). This helps to compensate for the enriched mixture, which passes into the branch pipe 9, and significantly levels the flow rate of the topdava into the branch suction channels. Apparatus of the Invention A device for supplying an air-fuel mixture to a multi-engine early-stage engine containing a down-flow carburetor equipped with a distribution chamber for receiving fuel-air mixture, the first branch pipe located) (:: at least to the Zishndru engine, a second branch pipe located on the other side of the distribution chamber for supplying the fuel-air mixture to at least another engine cylinder , a fuel jet, located transversely in the intake manifold, in the plane of branch pipes and in the direction of the first branch pipe so that most of the fuel is directed to the first branch pipe, the distribution chamber having a wall remote from the carburetor and opposite to the exhaust pipe , different in order to increase efficiency, the wall of the distribution chamber is inclined {"en to the axis of the inlet pipe towards the second branch pipe d l increased concentration of fuel supplied to the second branch pipe.
