What is cylinder liner cavitation in heavy diesel engines, and how do Supplemental Coolant Additives (SCAs) prevent it?

1. Oil leaking into the combustion chamber; SCAs seal the piston rings
2. High-frequency cylinder wall vibrations creating vacuum bubbles that collapse and erode the metal; SCAs form a protective chemical film
3. Fuel mixing with coolant in the radiator; SCAs absorb the fuel molecules
4. Rust building up inside the exhaust manifold; SCAs dissolve the rust flakes
