Abstract
A system for lubricating a crankshaft of an engine includes a first main journal including a first shaft and in fluid communication with an oil supply. The system also includes a first main journal oil passage in fluid communication with the oil supply extending through the first shaft. The system also includes a first pin journal including a first crank, and a first oil passage extending partially through the first crank in fluid communication with the first main journal oil passage. The system also includes a second pin journal including a second crank, and a second oil passage extending partially through the second crank in fluid communication with the first main journal oil passage. Each of the first oil passage extends at a first non-zero angle and the second oil passage extends at a second non-zero angle relative to the first main journal oil passage.
