← TechnologyWhich failure accelerates when an engine's 'piston slap' increases?
A)Connecting rod bearing wear✓
B)Crankshaft torsional vibration
C)Fuel injector nozzle erosion
D)Catalytic converter overheating
💡 Explanation
Increased piston slap leads to more connecting rod bearing wear, because the increased clearances cause larger impact forces during each combustion cycle. With increased forces resulting during the **fluid-film lubrication** mechanism, the bearing experiences wear more rapidly therefore, rather than the alternatives occurring, leading to earlier engine failure.
