合がある。 Some motorcycles have a cowling attached to the front of the body, and the cowling covers the front part of the body. The cowling is streamlined,
This has the effect of reducing wind turbulence caused by running, thereby reducing running resistance. It also has the effect of reducing the driver's fatigue by reducing the amount of wind that hits the driver while driving. When the cowling is installed, the engine will be placed inside the cowling, and a cooling air intake hole is provided in the front part of the cowling to allow the running air to hit the engine and cool it. . However, as the vehicle continues to drive, the temperature near the engine rises due to heat generated by the engine, warming the air. Since this high-temperature air is taken in as intake air, there is a disadvantage that the density is insufficient and the output is reduced.
この考案は、かかる点に鑑み改善したもので、
以下図面に示す本考案の実施例について説明す
る。 This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

側にリード弁９を取着する。 A cowling 2 is attached to the front part of a vehicle body 1, and the cowling 2 covers the front part of the vehicle body 1. Cowling 2 is
The cowling 2 is enclosed to the side, and the engine 3 is placed inside the cowling 2. cowling 2
A cooling air introduction hole 4 is provided on the front side of the
The engine 3 is cooled by the wind while the vehicle is running. However, in the present invention, on both sides of the engine 3,
The partition plate 5 is set up. An intake air introduction space 6 is provided between the outer side of the partition plate 5 and the inner side surface of the cowling 2. In this intake air introduction space 6, a carburetor 7 for each cylinder of the engine 3 is arranged. An air guide hole 8 is provided at the front end of the intake air introduction space 6, and a reed valve 9 is attached inside the air guide hole 8.
作用について説明する。 The effect will be explained.
オートバイが風を切つて走行すると、走行によ
り風の風圧で、リード弁９が開き、走行スピード

冷却した後の熱風が、吸気導入空間６に流れるこ
とが少く、暖められた空気を吸気に用いないの
で、充填効率がよく、出力が持続できる。 When the motorcycle runs against the wind, the reed valve 9 opens due to the pressure of the wind, and an amount of wind corresponding to the running speed enters the intake space 6 through the air guide hole 8 and flows from the inlet of the carburetor 7. This becomes the intake air that is inhaled. Since the intake air introduction space 6 is separated from the high temperature part of the engine 3 by the partition plate 5, hot air after cooling the engine 3 rarely flows into the intake air introduction space 6, and warm air is not used for intake. Therefore, the filling efficiency is good and the output can be sustained.

適宜調節ができる。 As explained above, this idea covers the front part of the vehicle body with a cowling, and the engine is mounted inside the cowling, with partition plates erected on both sides of the engine and intake air introduced between the cowling and both sides. A space is provided, a carburetor is placed in the intake air introduction space, and an introduction hole with a reed valve attached is drilled at the front end of the intake air introduction space.As the speed of traveling increases, the wind pressure of the reed valve decreases. The opening becomes larger, allowing wind to flow in and supplying intake air to the engine according to the driving speed. Since the partition plate prevents hot air from entering the intake air introduction space, expansion of the intake air due to heat can be prevented, the filling efficiency can be maintained at a high level, and a decrease in output can be prevented. The amount of air flowing into the air guide hole can be adjusted as appropriate by adjusting the spring strength of the reed valve.
