← TechnologyWhich 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.
