What are the lubrication methods for an engine?
1 Answers
Engine lubrication methods mainly include: 1. Splash Lubrication: A method that utilizes oil droplets splashed by rotating components like the crankshaft and camshaft during engine operation, or sprayed from oil holes on the connecting rod big end, to lubricate friction surfaces. It primarily lubricates the cylinder walls, cams, piston pins, etc. 2. Periodic Lubrication: This involves using grease applied at regular intervals for lubrication. It mainly lubricates components such as the generator, starter motor, and water pump bearings. 3. Pressure Lubrication: This method uses an oil pump to deliver lubricating oil under pressure to the friction surfaces of components, forming an oil film of certain thickness capable of withstanding mechanical loads to ensure reliable lubrication. It primarily serves high-speed and heavily loaded engine components.
