Abstract
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.
