Abstract: An anti-polish ring for an internal combustion engine is provided. The anti-polish ring includes an axially extending ring portion that is configured to scrape a top portion of a piston in a cylinder liner. The anti-polish ring is configured to accommodate passage of an intake or exhaust valve thereby. The anti-polish ring may include an alignment feature so that the anti-polish ring is inserted in a predetermined orientation in the cylinder. The anti-polish ring may include a heat shield and/or a seating member.

Abstract: Oil pan assemblies and methods of draining oil pans are disclosed. An example oil pan assembly includes an oil pan defining first and second sumps. The first sump has a first lower surface and the second sump has a second lower surface. The second lower surface is elevated along a vertical axis relative to the first lower surface. The oil pan assembly also includes a siphon tube extending from an inlet positioned in the second sump to an outlet positioned proximate a drain hole in the first sump. The siphon tube is configured to automatically transmit oil from the second sump to the first sump upon oil being drained from the drain hole.

Abstract translation: 公开了油盘组件和排油槽的方法。 示例性油盘组件包括限定第一和第二沉陷的油盘。 第一贮槽具有第一下表面，第二贮槽具有第二下表面。 第二下表面相对于第一下表面沿竖直轴线升高。 油盘组件还包括虹吸管，该虹吸管从位于第二贮槽中的入口延伸到靠近第一贮槽中排水孔的出口。 虹吸管构造成在从排水孔排出油时，将油从第二贮槽自动传递到第一贮槽。
