What are the lubrication methods for automobile engines?

There are three lubrication methods for automobile engines. The detailed information is as follows: 1. Splash lubrication: This method utilizes oil droplets splashed by rotating components such as the crankshaft and camshaft during engine operation, or oil sprayed from oil holes on the connecting rod big end to lubricate friction surfaces. 2. Periodic lubrication: This involves regular greasing for lubrication, primarily applied to components like generators, starters, and water pump bearings. 3. Pressure lubrication: An oil pump delivers lubricating oil under pressure to the friction surfaces of components, forming an oil film of sufficient thickness to withstand mechanical loads and ensure reliable lubrication.
I've always been into cars, and engine lubrication is crucial, mainly combining pressure lubrication and splash lubrication. Pressure lubrication relies on the oil pump to draw oil from the oil pan and send it through pipes to high-friction areas like the crankshaft and bearings. Splash lubrication occurs when the pistons and crankshaft move, flinging oil to lubricate the cylinder walls and piston rings. This mixed lubrication reduces friction between parts and extends engine life. I once experienced poor lubrication—my car made strange noises, and the engine ran hot. Upon inspection, I found the oil level was low and promptly changed it. Insufficient lubrication also accelerates wear, so I make it a habit to check the oil level every three months and use oil with the right viscosity. Regular maintenance helps prevent major issues and gives me peace of mind while driving.
As a car enthusiast, engine lubrication methods are actually quite fascinating: pressure lubrication works like a conveyor belt in the system, with the oil pump forcing lubricant to critical points; splash lubrication relies on component movement to distribute oil across surfaces. Lubrication isn't just about reducing friction—it also cools components and cleans away debris. When choosing engine oil, I pay attention to seasonal changes, using thinner oil in winter for easier lubrication. Effective lubrication depends on quality oil—using the wrong type can lead to insufficient pump pressure and rapid wear. Considering how crucial that protective oil film is for metal surfaces, I always stick with premium full-synthetic brands. These little insights make maintenance both simple and enjoyable.
