Engine Lubrication Methods?

[EmeryFitz]

Engine lubrication methods include pressure lubrication, splash lubrication, and grease lubrication. Below are detailed introductions to these engine lubrication methods: 1. Pressure lubrication: This method supplies oil to friction surfaces under a certain pressure. It is mainly used for lubricating heavily loaded friction surfaces such as main bearings, connecting rod bearings, and camshaft bearings. 2. Splash lubrication: This method uses oil droplets or oil mist splashed by moving parts during engine operation to lubricate friction surfaces. It is primarily used to lubricate lightly loaded surfaces such as cylinder walls, camshafts, lifters, valve stems, and rocker arms in the valve train. 3. Grease lubrication: This method involves periodically injecting grease through grease fittings to lubricate working surfaces of components, such as water pump and generator bearings.
