Which outcome occurs when asymmetric heating of piston rings?

💡 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.
