本発明は気筒毎に気化器を独立に備えた多気筒エンジン
を搭載する自動二輪車に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a motorcycle equipped with a multi-cylinder engine in which each cylinder is independently provided with a carburetor.
自動二輪車に気筒毎に気化器を独立に備えた多気筒エン
ジンを搭載する場合、その気化器の空気吸入口を全て同
一方向に車体の前方へ向けて配置するようにしたものが
提案されている。When a motorcycle is equipped with a multi-cylinder engine with an independent carburetor for each cylinder, it has been proposed that the air intake ports of the carburetors are all placed in the same direction toward the front of the vehicle body. .
（実開昭５８−４８９７７号公報参照）このように全て
の気化器をエンジン前方側に配置した場合、その気化器
の空気吸入口が前方へ突出した状態になるため、前輪と
の干渉によって前輪の上下ストロークに支障を来すこと
になる。そのため、上記のようなエンジンでは、車体に
対する搭載位置を一般のエンジンの場合よりも後方側に
移動するようにしなければならない。(Refer to Japanese Utility Model Application Publication No. 58-48977.) If all the carburetors are placed at the front of the engine in this way, the air intake ports of the carburetors will protrude forward, which may cause interference with the front wheels. This will interfere with the vertical stroke of the Therefore, in the above-mentioned engine, the mounting position with respect to the vehicle body must be moved to the rear side compared to the case of a general engine.
しかし、エンジンの車体に対する搭載位置が後方へ移動
すると、重心も後方に移動するため操安性が低下すると
いう問題がある。However, when the mounting position of the engine relative to the vehicle body moves rearward, the center of gravity also moves rearward, resulting in a problem in that steering stability deteriorates.
本発明の目的は、上述した従来の問題を解消し、気化器
を前方側に配置した多気筒エンジンを搭載した自動二輪
車において、その操安性を向上するようにすることにあ
る。An object of the present invention is to solve the above-mentioned conventional problems and to improve the maneuverability of a motorcycle equipped with a multi-cylinder engine in which a carburetor is disposed at the front side.
上記目的を達成する本発明は、気筒毎に気化器を独立に
備えた多気筒エンジンを搭載した自動二輪車において、
前記各気化器を前輪の後方において車体の前方に向けて
配置すると共に、その空気吸入口を車体の前後方向に対
し斜め外側に向けるようにしたことを特徴とするもので
ある。The present invention achieves the above object in a motorcycle equipped with a multi-cylinder engine in which each cylinder is independently equipped with a carburetor.
The present invention is characterized in that each of the carburetors is arranged behind the front wheels toward the front of the vehicle body, and its air intake ports are directed diagonally outward with respect to the longitudinal direction of the vehicle body.
以下、図に示す実施例によって本発明を説明する。 The present invention will be explained below with reference to embodiments shown in the figures.
第１図〜第３図は本発明の実施例からなる自動二輪車を
示すもので、１は車体フレーム、２はエンジン、３は前
輪、１０は車体前部を覆うカウルである。1 to 3 show a motorcycle according to an embodiment of the present invention, in which 1 is a body frame, 2 is an engine, 3 is a front wheel, and 10 is a cowl that covers the front part of the vehicle body.
この実施例において、上記エンジン２は前後Ｖ形の２気
筒４．４を有する構成になっている。In this embodiment, the engine 2 has two 4.4 cylinders in a V-shape, front and rear.
各気筒４はそれぞれ吸気側に気化器５を設けられ、排気
側に排気管６を設けているが、いずれも気化器５は全て
車体の前方に向けて配置され、排気管６が車体の後方へ
延びるようになっている。さらに、このように車体の前
側に配置された気化器５は、いずれもその空気吸入口５
ａを車体前後方向に対し斜め外側に向けるようにしてい
る。Each cylinder 4 is provided with a carburetor 5 on the intake side and an exhaust pipe 6 on the exhaust side, but all the carburetors 5 are arranged toward the front of the vehicle body, and the exhaust pipe 6 is located at the rear of the vehicle body. It is designed to extend to. Further, each of the carburetors 5 disposed on the front side of the vehicle body has its air intake port 5.
a is directed diagonally outward with respect to the longitudinal direction of the vehicle body.
上述の自動二輪車は、各気筒４の気化器５が全てエンジ
ンの前側に配置されているが、いずれも空気吸入口５ａ
を斜め外側に向けるようにしているため、この傾斜した
分だけ車体前後方向に占める気化器５の長さを短縮する
ようになっている。そのため、この長さが短縮した分だ
け、前輪３と干渉しないエンジン２の搭載位置を前方に
移動させることができるようになっている。また、ハの
字状に拡ずられた左右の空気吸入口５ａ、５ａの間に前
輪３を挿入する位置まで、エンジン２の搭載位置を前方
に移動させることもできる。In the above-mentioned motorcycle, all the carburetors 5 of each cylinder 4 are arranged on the front side of the engine, but all of them are connected to the air intake port 5a.
Since the carburetor 5 is oriented obliquely outward, the length of the carburetor 5 in the longitudinal direction of the vehicle body is shortened by the amount of this inclination. Therefore, the mounting position of the engine 2, which does not interfere with the front wheels 3, can be moved forward by the amount that the length is shortened. Further, the mounting position of the engine 2 can also be moved forward to a position where the front wheel 3 is inserted between the left and right air intake ports 5a, which are widened in a V-shape.
したがって、このようなエンジン搭載位置の前方移動に
よって重心が前方へ移動し、操安性の向上が可能になる
。Therefore, by moving the engine mounting position forward, the center of gravity moves forward, making it possible to improve maneuverability.
なお、上述した実施例は前後ｖ形の多気筒エンジンの場
合を例示したが、本発明は第４，５図に示すような並列
多気筒エンジンの場合にも適用することができる。また
、上記実施例はい４、
ずれも２気筒エンジンの場合を例示したが、本発明は３
気筒以上のエンジンにも適用することができる。Although the above-described embodiments have been exemplified in the case of a front and rear V-shaped multi-cylinder engine, the present invention can also be applied to a parallel multi-cylinder engine as shown in FIGS. 4 and 5. In addition, although the above-mentioned embodiment No. 4 and the case of a two-cylinder engine were illustrated, the present invention
It can also be applied to engines with more than one cylinder.
上述したように本発明は、気筒毎に気化器を独立に備え
た多気筒エンジンを搭載した自動二輪車において、前記
各気化器を前輪の後方において車体の前方に向けて配置
すると共に、その空気吸入口を車体の前後方向に対し斜
め外側に向けるようにしたものである。As described above, the present invention provides a motorcycle equipped with a multi-cylinder engine in which each cylinder is independently equipped with a carburetor, in which each of the carburetors is disposed behind the front wheels toward the front of the vehicle body, and the air intake The mouth is oriented diagonally outward with respect to the longitudinal direction of the vehicle body.
したがって、上記斜め配置によって気化器が車体前後方
向に占める長さを短縮することができ、その短縮分だけ
エンジンの搭載位置を前方へ移動することができる。ま
た、ハの字状に拡げられた左右の空気吸入口の間に前輪

もできる。したがって、この搭載位置の移動によって重
心を前方へ移動することができるので、操安性を向上す
ることができる。Therefore, the diagonal arrangement allows the length that the carburetor occupies in the longitudinal direction of the vehicle body to be reduced, and the mounting position of the engine can be moved forward by the amount of the reduction. It is also possible to move the engine mounting position forward so that the front wheels fit between the left and right air intake ports, which are widened in a V-shape. Therefore, by moving the mounting position, the center of gravity can be moved forward, thereby improving maneuverability.
