Hydrodynamic lubrication versus boundary lubrication

How Hydrodynamic lubrication keeps engine parts from touching versus boundary lubrication Automotive lubrication systems protect against metal-to-metal contact using both hydrodynamic lubrication and  boundary lubrication techniques. The difference between the two can be confusing to DIYers that think that engine lubrication is based more on oil viscosity than pressure. To understand the difference between hydrodynamic lubrication (also called film lubrication) and boundary lubrication we must first understand the difference between the words absorb and adsorb. Absorption is a dissolving/combining process — examples of absorption • When you add cream and … Read More
