Engine Lubrication Methods?
1 Answers
Lubrication methods are divided into pressure lubrication, splash lubrication, and grease lubrication. The specific lubrication methods of the engine are as follows: Pressure Lubrication: The engine oil is pumped by the oil pump to generate a certain pressure, then delivered through oil passages to lubricate various friction surfaces. Splash Lubrication: Utilizes the movement of the crankshaft and connecting rods to splash and spray the lubricating oil, forming oil droplets and mist to lubricate surfaces of components without oil passages. Grease Lubrication: Engine accessories such as the generator, water pump, and other bearings use grease lubrication, which requires regular replenishment or cleaning and replacement.
