Which risk significantly increases when a piston experiences excessive thermal stress beyond material yield strength?

💡 Explanation

When a piston experiences extreme thermal stress past its yield strength, plastic deformation occurs as the material expands unevenly, causing direct contact and friction against the cylinder wall. Therefore, cylinder wall scuffing results, rather than valve timing, injector clogging, or bearing failure which involve different mechanisms or locations.
