Abstract: An oil supply passage of a cylinder head increases design freedom of cylinder heads. The oil filter variously sets the oil supplying position through which oil enters into an oil filter. This improves fuel consumption by simplifying the oil supply passage of the cylinder head, reduces power loss of an oil pump, and decreases the size and weight of the cylinder head.

Abstract: A lubrication system for the timing chains of a V-type engine includes an oil supply means supplied by a single oil supply source. The oil supply means receives oil from a single spouting hole of a single main oil gallery and simultaneously supplies the oil to two timing chains, one of the left bank and the other of the right bank. Thereby the bulk of the cylinder block is reduced and the design and layout of the peripheral elements of the cylinders is simplified.
Abstract translation: 用于V型发动机的定时链的润滑系统包括由单个供油源供应的供油装置。 供油装置从单个主油库的单个喷射孔接收油，并同时将油供应到右岸中的一个左岸和另一个右岸。 因此，缸体的体积减小，并且气缸的外围元件的设计和布局被简化。
