う不具合を生ずる。In engines installed in motorcycles, in so-called front and rear VG engines whose surfaces are V-shaped front and rear, if the engine is air-cooled, the cooling air for the rear side is blown away by the front cylinder. There is a problem with the cooling of the hiroka being insufficient. On the other hand, in order to solve this problem of cooling power, it would be possible to use a water-cooled system, but in the case of a water-cooled system, the radiator is installed in front of the engine, so the wheelbase is increased by the amount of the radiator installed. As the wheelbase becomes longer, the frame also becomes longer, which increases the weight of the aircraft, leading to problems such as worsening fuel consumption.
本発明の目的は、上述のような従来の不具合をM消し、

せんとすることにある。The purpose of the present invention is to eliminate the above-mentioned conventional problems,
It is an object of the present invention to provide a V-type engine for a motorcycle, which improves the cooling performance of the front and rear V-type engines and allows the wheelbase to be made as long as an air-cooled engine.

The engine is characterized in that the cylinder m is water-cooled, and a radiator for water cooling is arranged above the front cylinder.

角度の大白い所謂L型と称するものも含むものとする。Note that in the present invention, vtJ includes what is called a so-called L-shape with a wide angle that sandwiches the %lIlyL cabinet.
以下、図に示す本発明の寅篩例により説明する。Hereinafter, an explanation will be given with reference to an example of a tora sieve of the present invention shown in the drawings.
図において、1は本発明によるV型エンジンであり、前
寛■1aとit簡1bとをそれぞれ前後にV型となるよ
うに配置している。このV型エンジン1は、自動二輪車

により支持されている。5はフロントフォーク4に支持
された前輪である。In the figure, reference numeral 1 denotes a V-type engine according to the present invention, in which a front opening 1a and an opening opening 1b are arranged in a V-shape at the front and rear, respectively. This V-type engine 1 is supported by a main vibe 2 and a down tube 3 that constitute the body of the motorcycle. 5 is a front wheel supported by the front fork 4.

イブロa、6bにより連結され、その冷却が水冷で行わ
れるようにな)ている。The front aperture 111a of the V-type engine 1 is provided with a large number of fins on its outer periphery so that cooling is performed by air. On the other hand, the rear j[111b is connected to the radiator 6 by a circulating vibro a and 6b, and is cooled by water cooling.
上記ラジェータ6は、前室111aの上方の比較的狭い

その容量は従来の水冷V型エンジン用のラジェータに比
べれば約二分の−でよいため、全体がコンパクトになり
、上述のように前室111a上方の狭いスペースにも十
分に収納可能になるのである。The radiator 6 is installed in a relatively narrow space above the front chamber 111a. That is, since the radiator 6 installed here only needs to cool the rear seat 1rlb,
Its capacity is about half that of a radiator for a conventional water-cooled V-type engine, making the whole compact, and as mentioned above, it can be stored in the narrow space above the front chamber 111a. .

用vVエンジンに比べて前後方向にβだけ後方へ債遺し
た位置にすることが可能となる。In the V-type engine of the motorcycle mentioned above, the rear j! E
lllb is cooled uniformly and favorably by water cooling via the radiator 6. Moreover, the capacity of the radiator 6 for cooling the VK air 11b is smaller than that of the conventional large radiator 6' that cools both the front and rear air cylinders.
Since it can be installed in a narrow space above the front cylinder instead of in front of the front cylinder, it can be installed in a position that is further back in the front-rear direction by β compared to conventional water-cooled VV engines. It becomes possible.
そのため、この距離lに相当するだけホイールベースが
従来の水冷用V型エンジン搭載の自動二輪車に比べて短
くなフている。Therefore, the wheelbase is shorter than that of a conventional motorcycle equipped with a water-cooled V-type engine by an amount corresponding to this distance l.
一方、上述のように後蒐簡冷却用のラジェータ6が前気
筒1aの上方に設置され、このラジェータ6が前寛11
1aに対する前方からの冷却風を遮ゐようなことがない
ため、前気筒1aの冷却は空冷により極めて良好に行わ
れることになる。On the other hand, as mentioned above, the radiator 6 for cooling the rear cylinder is installed above the front cylinder 1a, and this radiator 6 is connected to the front cylinder 11.
Since the cooling air from the front to the cylinder 1a is not blocked, the front cylinder 1a is cooled extremely well by air cooling.

となる。(3) As mentioned above, the V-type engine for a motorcycle according to the present invention has a plurality of IWTs arranged in the front and rear of the motorcycle, and the front cylinder is air-cooled and the rear chamber is water-cooled. In addition, since this water cooling radiator is an elliptical type placed above the front cylinder, by making it partially water cooled, it improves the cooling performance of both the front and rear cylinders of the front and rear V-type engine, and the radiator is placed above the front cylinder. This makes it possible to make the wheelbase as long as an air-cooled engine, and this short wheelbase also makes it possible to reduce the weight of the vehicle body and reduce the fuel consumption rate.
