Abstract:
An internal combustion engine comprising a first cylinder formed in a first cylinder bank, a second cylinder formed in a second cylinder bank, the cylinder banks oriented in a V-shaped formation with the first cylinder bank being generally on a first side of the engine and the second cylinder bank being generally on a second side of the engine, a crankcase enclosing at least a portion of a crankshaft therein, the crankshaft adapted to rotate in a manner creating a swirling flow of air within the crankcase, the crankcase divided into at least a first crankcase chamber communicating with the first cylinder and a second crankcase chamber communicating with the second cylinder, a first lubricant insertion port opening into the first crankcase chamber from the second side of the engine, and a second lubricant insertion port opening into the second crankcase chamber from the first side of the engine, the lubricant insertion ports communicating with a source of lubricant, the second lubricant insertion port opening into the second crankcase chamber in a direction substantially opposite the swirling flow, the source of lubricant being regulated by a control mechanism so that each lubricant insertion port delivers about 20-55 cc/hr of lubricant during engine idle.
