Abstract
An internal combustion engine, and method of distributing lubricant within an internal combustion engine, are disclosed. The internal combustion engine includes a crankcase having a floor, a pump supported by the floor, and a camshaft. The pump includes an inlet and an outlet. The camshaft has a cam, first and second camshaft ends, and an internal channel extending within the camshaft between the ends. The first end is supported by the pump or the floor. Rotation of the camshaft causes the pump to draw in lubricant via the inlet and to pump out at least some of the lubricant via the outlet. The outlet is positioned in proximity to the internal channel at the first camshaft end, so that at least some of the lubricant is pumped into the channel.
