We never referred to oxygen impingement in Engineering. Must be a Cummins term.cavitation and oxygen impingement are the same thing. When a bubble forms on the side of a liner and it 'explodes', it initiates the process as it removes a tiny amount of the outer treated part of the liner and allows the resultant hole to bore into the liner and eventually compromise the liner causing engine failure. I retired from a class 8 heavy duty truck dealership and we rarely saw that happening because most trucks either came with a coolant filter with a block of potassium permagnate inside or the owners used DCA4 additive which is deionized water with the Potassium in solution. The DCA 4 or or the charged coolant filters allows the potassium to 'coat' the outside of the liner, preventing cavitation or oxygen impingement. Kind of like taking water in a pan and heating it. The bubbles that form on the bottom of the pan as the water heats are exactly what happens with a liner.
Like I said, did a few, but not many and it always resulted in engine failure.
