ABSTRACT:
An engine lubrication system according to the present invention includes a pair of lubrication galleries which extend through the engine block between the ends of the engine crankshaft and communicate with the crankshaft bearing journals through a plurality of lubrication passages. The lubrication galleries are connected to the lubricant pump at opposite ends of the engine. Lubrication passages of one gallery combine with lubrication passages of the other gallery at the crankshaft bearing journals to compensate for the lubricant pressure loss through the galleries with distance from the lubricant pump.
