A fluid passage intersection () within a component () includes a supply passage () formed in the component (), a cavity () in fluid communication with the supply passage (), and at least one outlet passage () formed in the component () that is in fluid communication with the cavity ().

Engine fluid passage intersection and method

A crankcase () for an engine includes a first bank () of cylinders that has a plurality of cylinder bores () formed therein, and a second bank () of cylinders that includes an additional plurality of cylinder bores (). The second bank () is at an angle with respect to the first bank (). A valley structure () is located between the first bank () and the second bank (). A gallery () is located between the first bank (), the second bank (), and the valley structure (). The gallery () has at least one rear opening () that fluidly connects the gallery () to a rear portion () of the crankcase. At least one front opening () fluidly connects the gallery () to a front portion () of the crankcase (). At least one breather opening () fluidly connects the gallery () to an outer valley surface ().

Crankcase for an internal combustion engine

A component () for an internal combustion engine includes a plurality of as-cast features (e.g.) formed thereon, and a plurality of machined features (e.g.). The component () also includes at least one witness mark (), the witness mark () including a cavity () surrounded by a first lateral surface (), a first inclined surface (), a second inclined surface (), and a valley surface (). The at least one witness mark () is formed during a casting operation, and is used to locate the component () on a fixture (). The plurality of machined features () do not encroach onto an area of the at least one witness mark (). The first inclined surface () and the second inclined surface () are at an angle (&#x3b1;) with respect to each other.
