An internal combustion engine includes an engine lubrication fluid storage system with a primary storage volume and a secondary storage volume that is separate from the primary storage volume. The secondary storage volume is linked to the primary storage volume with a fluid flow path that is throttled so that lubrication fluid is stored in the secondary storage volume during engine operation, and drains from the secondary storage volume to the primary storage volume when the engine is not running.

Lubrication fluid storage system

An internal combustion engine includes an engine lubrication fluid system with a main rifle for distribution of filtered lubrication fluid to a plurality of engine components through a plurality of secondary rifles connected to the main rifle. The system also includes a bypass for bypassing the filter in response to certain engine operating conditions. The bypass is connected to at least one of the secondary rifles so that unfiltered lubrication fluid is not provided to certain engine components under filter bypass conditions, and provided directly to certain other engine components for which unfiltered lubrication fluid is less problematic.
