← TechnologyWhich consequence results when cylinder walls wear unevenly?
A)Piston ring blow-by increases✓
B)Valve timing becomes significantly advanced
C)Connecting rod bearings rapidly degrade
D)Fuel injector nozzle clogging accelerates
💡 Explanation
Increased piston ring blow-by occurs due to gaps formed between worn spots. This reduces compression because the seals effectiveness decreases, therefore boosting cylinder pressure lowers, rather than leading directly to valve or fuel injector issues.
