Which outcome occurs when particulate contaminants bypass piston ring sealing?

A)Cylinder wall friction increases rapidly
B)Exhaust valve temperatures reduce sharply
C)Intake manifold pressure stabilizes quickly
D)Fuel injector spray pattern becomes uniform

💡 Explanation

Increased cylinder wall friction occurs through abrasive wear because particles embed into the piston and cylinder surfaces, grinding them via three-body abrasion. Therefore, friction increases, rather than smoother operation, if particles weren't embedded within it.
