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: The present disclosure provides a lubrication system comprising: a pump having an inlet in fluid communication with a lubricant source and an outlet; a cooler having an inlet in fluid communication with the outlet of the pump and an outlet; a lubrication filter having an inlet in fluid communication with the outlet of the cooler and an outlet; a first delivery path in fluid communication with the outlet of the lubrication filter, the first delivery path being configured to deliver cooled, filtered lubricant to a bearing system of an engine; and a second delivery path in fluid communication with the outlet of the pump, the second delivery path being configured to deliver uncooled, unfiltered lubricant to piston cooling nozzles of the engine.

Abstract: An apparatus comprises an engine, an exhaust manifold fluidly coupled thereto, and an auxiliary system positioned downstream of and fluidly coupled to the exhaust manifold. A slip joint assembly fluidly couples the exhaust manifold to the auxiliary system and includes a slip joint male portion fluidly coupled to the exhaust manifold which includes a plurality of lobes positioned on an outer surface of the male portion. The male portion defines a first passageway in fluidic communication with the exhaust manifold. The assembly also includes a slip joint female portion fluidly coupled to the auxiliary system and including a second passageway. The male portion is insertable into the female portion for fluidly coupling the male portion to the female portion. Only the plurality of lobes contact an inner surface of the second passageway. Moreover, the male portion is axially slidable within the second passageway while maintaining the fluid coupling therebetween.
