Which risk increases when exceeding design limits for connecting rod angularity relative to the crankshaft?

A)Accelerated piston skirt wear
B)Increased cylinder head temperature
C)Reduced valve train durability
D)Elevated exhaust gas backpressure

💡 Explanation

When connecting rod angularity exceeds design limits, asymmetric side loading on the piston increases, causing increased friction and accelerated wear of the piston skirt because the piston rocks excessively. Therefore, accelerated piston skirt wear results, rather than those others which stem from unrelated engine problems.
