Which outcome occurs when the piston ring end gap is too small in an internal combustion engine?

A)Increased oil consumption from blow-by

B)Cylinder wall scoring from thermal expansion✓

C)Reduced engine power from compression loss

D)Detonation from increased cylinder pressure

💡 Explanation

When the piston ring end gap is insufficient, thermal expansion causes the ring ends to butt together because the increased length can cause scoring on the cylinder wall. therefore cylinder wall scoring results, rathen than alternatives blow-by, power loss, or detonation which all occur with larger gaps or other engine malfuctions.
