Claim Text:
1. A method of preventing overfill of a crankcase oil sump in an engine of a generator set, the method comprising: receiving excess oil from the crankcase oil sump in the engine of the generator set by an inlet of an overflow conduit, including excess oil passively entering the inlet of the overflow conduit when an excess amount of oil inside the crankcase oil sump is above an amount of oil to be contained within a predetermined oil level inside the crankcase oil sump; directing the excess oil through the inlet of the overflow conduit, through a passage of the overflow conduit, and through an outlet of the overflow conduit, wherein directing the excess oil includes directing the excess oil out of the engine crankcase oil sump when the excess oil exceeds the predetermined oil level to a reservoir located relatively at or lower than the predetermined oil level; and controlling a flow of oil through the inlet of the overflow conduit to limit the amount of oil inside the engine crankcase oil sump to a level at or lower than the predetermined oil level, wherein one of the outlet and the inlet of the overflow conduit is positioned above the predetermined oil level of the crankcase oil sump.
