Beschreibung
Zusammenfassung:	An oil pump for an engine is disclosed. The oil pump may include a first pump mechanism configured to supply oil to a main lubrication passage of the engine and a second pump mechanism configured to supply oil to a piston cooling passage of the engine. The first pump mechanism may be designed for a first type of engine and the second pump mechanism may be designed for a second type of engine. The first type of engine may have a larger number of cylinders than the second type of engine. 公开了一种用于发动机的油泵。油泵可包括配置成向发动机的主润滑通道供应油的第一泵机构和配置成向发动机的活塞冷却通道供应油的第二泵机构。第一泵机构可设计用于第一类型的发动机，第二泵机构可设计用于第二类型的发动机。第一类型的发动机可具有比第二类型的发动机更大量的气缸。
