Lubrication SystemQuestions and Answers Already Passed Engine Oil Is the lubricant for moving parts in an engine. Oil Film Separates engine parts to prevent metal-on-metal contact. Oil Clearance The small space between moving engine parts for the lubricating oil film. Friction Bearing Also called a plain bearing, has two smooth surfaces sliding on each other. Anti-friction bearing Uses balls or rollers to avoid a sliding action between the bearing surfaces. Oil Viscosity Is the thickne...
