Abstract
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.
