The first and second carburetors are arranged between the first and second cylinders so that their intake cylinders are close to each other and intersect with each other.
Even in a narrow space between the first and second cylinders,
The intake cylinder of a predetermined length of the carburetor can be arranged without bending, and therefore, the inertial effect of the intake air can be fully utilized to improve the output performance of the engine.
また、第１及び第２気化器の吸気胴の交差により両吸気
胴の入口は互いに反対方向に開口することになるから、
両吸気胴の近接配置によるも、吸気干渉が極めて少なく

とができる。Furthermore, due to the intersection of the intake shells of the first and second carburetors, the inlets of both intake shells open in opposite directions.
Due to the close arrangement of both intake cylinders, there is extremely little intake air interference, and the air-fuel mixture can be stably supplied from each carburetor to the corresponding cylinder.
さらに、両吸気胴の近接により気化器装置全体の横幅が
最小限に短縮され、これを第１及び第２気筒間の狭小な
場所にコンパクトに収めることができる。Further, due to the proximity of both intake cylinders, the width of the entire carburetor device is reduced to a minimum, and it can be compactly accommodated in a narrow space between the first and second cylinders.

積を必要最小限度に抑えることができる。Furthermore, since each float chamber of the first and second vaporizers is arranged between the two air cylinders below the intersection of the two air intake cylinders,
The space between the air cylinders of both eyes can be effectively used to install the float chambers, making the overall structure even more compact.Moreover, each float chamber is integrally formed at the bottom of each air cylinder. It consists of a float chamber main body and a lower cover that is joined to the open lower surface of the float chamber main body, and the joint surface of these is inclined with respect to the horizontal plane at an angle smaller than the inclination angle of the intake cylinder. Regardless of the inclined arrangement of the torso,
Since the float chamber has a wide cross-sectional area, it is possible to easily install a float valve, etc., and the fuel storage volume of the float chamber can be suppressed to the necessary minimum.
