← TechnologyWhich outcome results when rapid piston acceleration exceeds oil film strength?
A)Boundary lubrication wear increases✓
B)Volumetric efficiency improves rapidly
C)Thermal management decreases
D)Detonation sensitivity margin increases
💡 Explanation
Increased piston acceleration can overload the oil film, causing it to rupture and leading to increased boundary lubrication wear because direct contact between the piston and cylinder occurs. Therefore, wear increases; rather than improved efficiency because friction directly offsets any positive gains.
