Which risk increases when a heat engine cylinder reaches its designed temperature limit?

💡 Explanation

Excessive temperatures cause piston ring thermal expansion, potentially leading to engine seizure because the tight tolerances increase friction; therefore, thermal expansion generates elevated risk, rather than decreased efficiency or improved exhaust sealing at the valve seats.
