Well the heat generated in degrees F is 46,340 degrees, hot on the baby....Even though the article doesn't mention it.
Explosion-Generated Collapsing Vacuum Bubbles Reach 20,000 Kelvin

What parts can degrade if vacuum bubbles form on the surface then explosively collapse? Hint: They see huge shock, causing high frequency vibration. Not all diesel engines have the item in question, but almost all large ones do.
Nope.i'll take an uneducated guess...Injectors?
It's liner cavitation, specifically. There are a few cases of some engines that have parent bore blocks with cavitation pitting issues, but they are relatively uncommon.Well, I would say it's where the coolant meets the cylinder walls, which can cause cavitation, but you threw me by saying not all diesel engines have them.
It makes rebuilds much, much easier. The engine can stay in the truck. It is NOT cheaper to do it this way. Not all engines with removable liners have liners in direct contact with water, but many do.Regarding the liners in the class 8 engines, their purpose is to make a rebuild of that engine possible, due to cavitation effects on cylinder walls ? or just cheaper, ?
Sounds like an expensive lesson.Started to say that I had pulled the liner on a Mack 300 , then I remembered that I just pulled the piston, valve punched a hole in the top of cylinder, due to some one trying make an R model Mack with a 300 hp 5 speed tranny run 85 MPH . One piston and several cylinder heads later that some one realized that this idea might not be a good one.
