等の不都合があった。[Detailed Description of the Invention] In general, in a water-cooled internal combustion engine for a motorcycle, parts that are not exposed to the wind caused by driving are evenly cooled, so smooth operation is possible regardless of the operating state of the engine. However, the radiator is relatively large and has many restrictions on installation.
本発明はこのような不都合を解消した自動二輪車用水冷
内燃機関の改良に係り、その目的とする処は、水冷却系
統の負担を軽減した冷却性能の高い内燃機関を供する点
にある。The present invention relates to an improvement of a water-cooled internal combustion engine for a motorcycle that eliminates such disadvantages, and its purpose is to provide an internal combustion engine with high cooling performance that reduces the burden on the water cooling system.
以下図面に図示された本発明の一実施例について説明す
る。An embodiment of the present invention illustrated in the drawings will be described below.
ｌは自動二輪車用二気筒Ｖ型四サイクル−水冷ガソリン
エンジンで、同エンジン１では、クランク軸が横方向に
指向し、シリンダー２が前後にＶ型に配置されている。1 is a two-cylinder, V-type, four-stroke, water-cooled gasoline engine for motorcycles; the engine 1 has a crankshaft oriented laterally, and cylinders 2 arranged in a V-shape in the front and rear.

介して水ポンプ８の吸入口に接続されている。Furthermore, a water pump 8 is attached to the engine 1, the discharge port of the water pump 8 is connected to the lower end of the water jacket 4 of the cylinder 2 via a water pipe 9, and the upper end of the water jacket 5 of the cylinder head 3 is connected to a water vibrator. 10
It is connected to the upper end of a radiator 12 via a thermostat 11 therein, and the lower end of the radiator 12 is connected to an inlet of a water pump 8 via a water pipe 13.

熱は冷却水で冷却され、ラジェータ１２で放熱される。Since the illustrated embodiment is configured as described above, when the engine 1 is operated, the water pump 8 is put into operation, and the cooling water is supplied from the water pump 8 to the water jacket 4 of the cylinder 2 via the water pipe 9. is sent from the water jacket 5 of the cylinder head 3 to the radiator I2 via the water pipe 10, and from the radiator 12 is returned to the water pump 8. In this way, the heat generated by the operation of the engine 1 is cooled by the cooling water, and is sent to the radiator I2. Heat is dissipated at 12.
また自動二輪車の走行に伴ないシリンダー２およびシリ
ンダーヘッド３は走行風を受け、その冷却フィン６．７
よりエンジン１の熱により温められた水はそこでも冷却
されること＼なる。In addition, as the motorcycle travels, the cylinder 2 and cylinder head 3 are exposed to the traveling wind, and the cooling fins 6, 7
Therefore, the water heated by the heat of the engine 1 is also cooled there.
従って、エンジン１め出力に比べてラジェータ１２の容
量が小さくできる。Therefore, the capacity of the radiator 12 can be made smaller than the first output of the engine.
またエンジン１のシリンダー２およびシリンダーヘッド
３がウォータージャケット４．５で均等に冷却されるの
で、走行風を受けない部分の局部的過熱が防止される。Further, since the cylinder 2 and cylinder head 3 of the engine 1 are uniformly cooled by the water jacket 4.5, local overheating of the portions not exposed to the running wind is prevented.
さらにまたシリンダー２およびシリンダーヘッド３には

タを軽量小型化することができる。As described above, the present invention provides a water-cooled internal combustion engine for motorcycles in which cooling fins are provided on either or both of the full width of the cylinder and the cylinder head, so that the heat load of the radiator is borne by the cooling fins. The radiator can be made lighter and smaller.
また本発明においては、水冷内燃機関でも、冷却フィン
