← TechnologyWhich risk increases when incorrect piston ring end gap is installed in an internal combustion engine?
A)Cylinder scoring from thermal expansion✓
B)Valve float from reduced combustion pressure
C)Bearing failure from oil dilution
D)Turbocharger overspeed from exhaust gas blow-by
💡 Explanation
When insufficient piston ring end gap exists, thermal expansion of the ring during engine operation causes the ring ends to butt together, creating excessive radial pressure against the cylinder wall. Therefore cylinder scoring results, rather than valve float, bearing failure, or turbocharger overspeed which depend on different mechanisms.
