ことができる等の作用・効果を奏するものである。In other words, the present invention is a type multi-cylinder engine in which two valve camshafts, one for the left cylinder and the other for the right cylinder, are placed inside the bank, and the cam chambers for the left and right cylinders are common. A weir is provided to connect the bearings for the left and right rows of each cylinder to make the cam chamber an independent space for each cylinder, and lubricating oil is introduced into this space to create an oil sump for each cylinder. With this configuration, lubrication between the cam and tappet can be guaranteed, and even when the engine is operated at an angle in the direction of the crankshaft, each joint is The lubricating oil can be secured in the oil sump, and the weir can function as a reinforcing member that connects the left cylinder and the right cylinder.
次に、図面により本考案の実施例を説明する。Next, embodiments of the present invention will be described with reference to the drawings.
図において、Ｖ形多気筒機関１０は左側の傾斜シリンダ
列１と右側の傾斜シリンダ列２と両者に共通のクランク
ケース３により、主要部が形成される。In the figure, the main part of a V-shaped multi-cylinder engine 10 is formed by an inclined cylinder row 1 on the left side, an inclined cylinder row 2 on the right side, and a crankcase 3 common to both.
５は左列用のカム軸、６は右列用のカム軸で、カム軸上
の各カムには各気筒毎に設けられた吸・排気弁用のタペ
ット９が摺接する。5 is a camshaft for the left row, and 6 is a camshaft for the right row. Tappets 9 for intake and exhaust valves provided for each cylinder are in sliding contact with each cam on the camshaft.
４は弁押し棒、７はカム軸軸受、１１はシリンダヘッド
、１２はヘッドボルト、１３は連接棒、１４は冷却水ジ
ャケット、１５は燃料噴射ポンプで、これらはいずれも
従来のものと同じ構造である。4 is a valve push rod, 7 is a camshaft bearing, 11 is a cylinder head, 12 is a head bolt, 13 is a connecting rod, 14 is a cooling water jacket, and 15 is a fuel injection pump, all of which have the same structure as the conventional one. It is.
８は両カム軸の配置された空間（カム室）に突設した堰
で、該堰８は各シリンダ毎の左列用と右列用の軸受部を
結ぶ位置に、カム室を各気筒毎の独立した室１６に分割
するように、シリンダブロックに一体的に突設されてい
る。8 is a weir protruding into the space (cam chamber) where both camshafts are arranged, and this weir 8 is located at a position connecting the bearings for the left row and the right row for each cylinder, and the cam chamber is installed for each cylinder. The cylinder block is integrally protruded from the cylinder block so as to be divided into independent chambers 16.
そしてこの独立した室１６に潤滑油を充填することによ
り、この室１６を各気筒毎の、弁カム用の、独立した油
だめに形成するものである。By filling this independent chamber 16 with lubricating oil, this chamber 16 is formed as an independent oil reservoir for the valve cam for each cylinder.
以上のように、本考案では弁カム軸を左のシリンダ列２
とによって形成される■バンクの内側に配置し、かつカ
ム室を各気筒毎に独立状態となるように、堰で仕切って
油だめとしたため、カムとタペット９との間の潤滑が確
実になされることになる。As described above, in this invention, the valve camshaft is connected to the left cylinder row 2.
The cam chamber is placed inside the bank formed by the cylinder, and the cam chamber is separated by a weir and used as an oil reservoir so that each cylinder is independent, ensuring lubrication between the cam and the tappet 9. That will happen.
さらに、機関本体がクランク軸方向に傾斜しても、各油
だめ内には潤滑油が残るから、このような運転状態のと
きにおいてもタペットの潤滑は確保されることになる。Furthermore, even if the engine body tilts in the direction of the crankshaft, lubricating oil remains in each oil sump, so lubrication of the tappets is ensured even under such operating conditions.
さらに堰８は左列用の軸受部と右列用の軸受部を結んで
形成されているから、シリンダブロックの補強リブとし
ての作用をも奏するものであり、本考案の実用上の効果
は顕著である。Furthermore, since the weir 8 is formed by connecting the bearing part for the left row and the bearing part for the right row, it also functions as a reinforcing rib for the cylinder block, and the practical effect of the present invention is remarkable. It is.
