In some engines, a carburetor is connected to the intake hole, and the carburetor atomizes and mixes fuel into the intake air, and supplies the fuel to the engine. Also, a carburetor with a single float chamber at the bottom and intake passages lined up on the left and right sides is used in multi-cylinder engines. Since the engine takes in air rapidly and intermittently, the intake air pulsates and blows back, which can reduce the intake efficiency, especially in the low rotation speed range.

In view of these points, this idea is a carburetor with two intake passages arranged side by side, focusing on the space in the center between the two intake passages, and by turning this space into an interference room for the intake air, the cost can be reduced. The purpose of the present invention is to obtain a carburetor that improves low-speed output by forming an interference chamber without the need for an interference chamber and improving intake efficiency particularly in a low-speed range.

させる。横孔７は直径８mm〜10mmが適切である。 1 and 2 show an embodiment of the present invention. The carburetor 1 has two intake passages 2 arranged side by side, and the outlet of each intake passage 2 is connected to the intake hole of each cylinder of a multi-cylinder engine. The two intake passages 2 are designed to suck fuel from one float chamber 3 provided on the lower side. The inlet 4 forms an ellipse formed by combining the two intake passages 2 and is connected to the outlet of the air cleaner. Two intake passages 2 have a substantially circular cross section, and an inlet 4
Since it is elliptical, a space 5 having a substantially triangular or trapezoidal cross section is formed above and below the center. This idea utilizes the space 5 as an intake interference chamber. The space 5 is partitioned into upper and lower sections by providing a partition 6 in the center, and communicates with the left and right intake passages 2 through horizontal holes 7, respectively. The diameter of the horizontal hole 7 is suitably 8 mm to 10 mm.

る。 Thus, the central space 5 communicates with the intake passage 2 through the horizontal hole 7 and becomes an intake interference chamber, which interferes with the pulsation of intake air flowing in the intake passage 2 intermittently.
Moreover, primarily, the intake air in the intake interference chamber path can be sucked, and the intake efficiency can be improved. In this way, the effect is produced particularly in the low speed range where the interval between intakes is long, and the low speed output can be improved. In addition, the central space 5 is originally formed in a carburetor in which the two intake passages 2 are arranged side by side, and can be created by simply adding the horizontal holes 7, which has the advantage of being possible with almost no increase in cost. be.

As explained above, this invention has an oval inlet connected to the cleaner, and in a carburetor with two intake passages arranged side by side in this oval inlet, the central space and The intake passages are connected through horizontal holes and the central space is used as an intake interference chamber, which interferes with the pulsation of intake air and also serves as a volume chamber that primarily supplies intake air, improving intake efficiency, especially at low speeds. It is possible to improve the output of the area. Further, since it is only necessary to additionally form a horizontal hole, there is an advantage that the cost can be reduced.
