Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a V type engine capable of sharing a cylinder head besides it is possible to adjust the amount of oil to the hydraulic oil passage of a valve operation change mechanism and the lubrication oil passage of a valve gear.SOLUTION: A front cylinder head 4F and a rear cylinder head 4R are composed of a shared cylinder head 60 whose cylinder bank directions are opposite to each other. At both ends of respective cylinder bank directions of the front cylinder head 4F and the rear cylinder head 4R, a plurality of distribution oil passages 47 for distributing oil to a valve operation changing mechanisms (23 and 24) are formed so as to open to the upper surface, the valve operation changing mechanisms being for changing at least one lift operation of the front valve gear 21F, the rear valve gear 21R, or the intake and exhaust valve 17 by hydraulic drive from the main gallery 46. At least one of the plurality of distribution oil passages 47 is provided with an oil amount adjustment mechanism (100) for adjusting the oil amount.SELECTED DRAWING: Figure 5
【課題】弁動作変更機構の作動油路と動弁機構の潤滑油路とへの油量を調整可能にした上で、シリンダヘッドを共用化できるV型エンジンを提供する。【解決手段】フロントシリンダヘッド4F及びリヤシリンダヘッド4Rは、シリンダ列方向が互いに逆向きとされた共用シリンダヘッド60からなる。フロントシリンダヘッド4F及びリヤシリンダヘッド4Rのシリンダ列方向の両端部のそれぞれには、メインギャラリ46からフロント動弁機構21F、リヤ動弁機構21R、又は油圧駆動によって吸排気バルブ17の少なくとも一方のリフト動作を変更する弁動作変更機構(23、24)にオイルを分配するための複数の分配油路47が上面に開口するように形成される。複数の分配油路47のうちの少なくとも1つに、油量を調整する油量調整機構(100)が設けられる。【選択図】図5 |
