Abstract

Disclosed herein is a lubrication system for an internal combustion engine including a lubricant reservoir, a lubricant dispersing device disposed in communication with the lubricant reservoir, and a lubrication apparatus including a recess integrally formed with an engine housing and an elongated trough disposed substantially within the recess and in fluid communication with a shaft bearing. The recess has an opening that extends radially outward relative to the shaft axis such that the lubricant dispersing device can disperse lubricant, during at least a portion of the engine cycle, along a direct and substantially unobstructed path into the recess. The trough is adapted to direct the lubricant received in the recess to the shaft bearing. The trough also extends radially outward and is inclined downwardly in a direction toward the shaft bearing. The recess further includes a back surface and a sidewall disposed substantially adjacent to the shaft bearing, which define a substantially unobstructed space between the recess opening and the back surface.
