本発明は燃料タンクの前方に気化器を配置するようにし
た自動二輪車の燃料供給部構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a fuel supply structure for a motorcycle in which a carburetor is disposed in front of a fuel tank.
一般に自動二輪車の燃料タンクはエンジン上方に配置さ
れているが、この燃料タンクが配置される部分に、空気
清浄器を燃料タンクと共に前後に配置し、それに伴って
気化器が燃料タンク前方に配置されるようにしたものが
ある。このように燃料タンクの前方に気化器等が配置さ
れた構成では、その外観を良好にするため、これら気化
器や燃料タンク等の燃料供給部の上側および左右両側を
カバー等の覆い部で覆うようにしたものがある。Generally, the fuel tank of a motorcycle is placed above the engine, but an air purifier is placed in front and behind the fuel tank along with the fuel tank, and a carburetor is placed in front of the fuel tank. There is something that looks like this. In a configuration where the carburetor, etc. is placed in front of the fuel tank, in order to improve its appearance, cover the upper side and both left and right sides of the fuel supply section of the carburetor, fuel tank, etc. with a covering part such as a cover. There is something like this.
ところが、このように燃料供給部が覆い部で覆われた構
造では、下方のエンジンからの熱気が覆い部の中にこも
るため１、気化器の温度が上昇して燃料中に気泡を生じ
やくなり、それによって気化器の燃料が流れにくくなっ
たり、混合気が薄（なり、エンジンの出力が低下するよ
うになる。However, in this structure where the fuel supply section is covered by a cover, hot air from the engine below gets trapped inside the cover, causing the temperature of the carburetor to rise and creating bubbles in the fuel. This makes it difficult for fuel to flow through the carburetor, and the air-fuel mixture becomes lean, resulting in a decrease in engine output.
本発明の目的は、燃料タンク前方に気化器を配置した燃
料供給部を覆い部で覆ったものであっても、気化器に極
端な温度上昇がなく、安定したエンジン出力を発揮でき
るようにする自動二輪車の燃料供給部構造を提供するこ
とにある。An object of the present invention is to provide a stable engine output without causing an extreme temperature rise in the carburetor even if the fuel supply section in which the carburetor is placed in front of the fuel tank is covered with a cover section. An object of the present invention is to provide a fuel supply structure for a motorcycle.
上記目的を達成する本発明は、燃料タンクの前方に気化
器を配置し、この前後に配置した燃料タンク、気化器等
の集合部の上側と左右両側とを覆い部で覆った構成にし
た自動二輪車において、前記燃料タンクの前部側の左右
両側部に斜め後方向へ向かう案内面を有する凹部を形成
し、この凹部に対応させて前記覆い部に外側へ抜ける開
口を設けたことを特徴とするものである。To achieve the above object, the present invention has a structure in which a carburetor is arranged in front of a fuel tank, and the upper side and both left and right sides of a gathering part of the fuel tank, carburetor, etc. arranged before and after this are covered with a cover part. In the two-wheeled vehicle, a recessed portion having a guide surface facing diagonally rearward is formed on both left and right sides of the front side of the fuel tank, and an opening extending to the outside is provided in the cover portion corresponding to the recessed portion. It is something to do.
以下、本発明を図に示す実施例により説明する。 The present invention will be explained below with reference to embodiments shown in the drawings.
第１．２図において、１．１は上下方向に幅広に形成さ
れたアルミニウム材の主フレーム、２はエンジン、３は
シートである。シート３の前方には空気清浄器４と燃料
タンク５とが前後に配置され、また上記空気清浄器４の
下方には気化器６が接続され、気化器６はさらにエンジ
ン２に接続されて燃料供給部を構成している。In Fig. 1.2, 1.1 is a main frame made of aluminum that is wide in the vertical direction, 2 is an engine, and 3 is a seat. An air purifier 4 and a fuel tank 5 are arranged in front of the seat 3, and a carburetor 6 is connected below the air purifier 4. The carburetor 6 is further connected to the engine 2 to supply fuel. It constitutes a supply section.
空気清浄器４と燃料タンク５とはカバー７により上側と
左右両側とが覆われており、また空気清浄器４下方の気
化器６は幅広の主フレーム１．１によって左右両側が覆
われている。このように燃料タンク５．空気清浄器４．
気化器６等の燃料供給部がカバー７や主フレーム１等の
覆い部に覆われることにより外側からは見えなくなり、
外観を良好にしている。The air purifier 4 and the fuel tank 5 are covered by a cover 7 on the upper side and on both left and right sides, and the carburetor 6 below the air purifier 4 is covered on both left and right sides by a wide main frame 1.1. . In this way, the fuel tank 5. Air purifier 4.
The fuel supply parts such as the carburetor 6 are covered by the cover parts such as the cover 7 and the main frame 1, so that they are not visible from the outside.
It has a good appearance.
上記燃料タンク５の前部側の下部には、第３゜４図に示
すように、左右両側に斜め後方向に向けた案内面１１ｓ
、ＩＩｓを有する凹部１１゜１１が形成され、またこの
凹部１１，１１に対応して、上記カバー７の両側部には
それぞれ外側へ抜ける開ロアａ、７ａが設けられている
。At the lower part of the front side of the fuel tank 5, as shown in FIG.
, IIs are formed, and corresponding to the recesses 11, 11, opening lowers a, 7a are provided on both sides of the cover 7, respectively, so as to extend outward.
上述した構成の自動二輪車によると、走行によって車体
前方の主フレーム１． １の下側から侵入した風は気化
器６．−・−・−２６を通過して、これらを冷却を行っ
たのち、燃料タンク５の前面において左右に分離され、
左右の凹部１１゜１１の案内面１１ｓ、ＩＩｓに沿って
カバ−７両側部の開ロアａ、７ａから外側へ排出される
〜。According to the motorcycle having the above-described configuration, the main frame 1 at the front of the vehicle body is damaged while driving. The wind that entered from the bottom of 1 is the vaporizer 6. - After passing through -26 and cooling them, they are separated into left and right at the front of the fuel tank 5,
It is discharged to the outside from the opening lowers a, 7a on both sides of the cover 7 along the guide surfaces 11s, IIs of the left and right recesses 11°11.
したがって、−エンジン２から上昇した熱気がカバー７
や幅広の主フレーム１，１等の覆い部の中にこもること
はなく、常に覆い部内を適温に維持することができる。Therefore, - the hot air rising from the engine 2
The temperature inside the cover part can always be maintained at an appropriate temperature without being trapped in the cover part of the wide main frames 1, 1, etc.
したがって、上記自動二輪車では、燃料タンク５の前方
に気化器６が配置された燃料供給部が、カバー７や主フ
レーム１．１による覆い部によって囲まれた構造ではあ
るが、気化器６が温度上昇して燃料の流れを悪くしたり
、混合気を薄（したりすることはなく、またそれによっ
てエンジン２の出力低下を招くことはない。Therefore, although the above motorcycle has a structure in which the fuel supply section in which the carburetor 6 is disposed in front of the fuel tank 5 is surrounded by the cover 7 and the main frame 1.1, the carburetor 6 It will not rise and impair the flow of fuel or make the air-fuel mixture lean, and will not cause a decrease in the output of the engine 2.
