← TechnologyWhich outcome occurs when asymmetric heating of piston rings?
A)Increased blow-by gas leakage✓
B)Reduced connecting rod stress
C)Enhanced oil film thickness
D)Decreased cylinder bore wear
💡 Explanation
Increased blow-by gas leakage results from thermal distortion. Non-uniform heating causes a change in radial tension via **thermoelastic deformation**; therefore, inadequate sealing occurs because the rings no longer conform cylindrically, rather than maintaining optimal contact and preventing leaks.
