Which consequence occurs when a heat engine's exhaust cooling fails?

A)Decreased pressure differential available
B)Increased thermal bypass inefficiencies
C)Optimized combustion stoichiometry achieved
D)Reduced turbine blade fatigue cracking

💡 Explanation

Increased exhaust temperature raises cooling demands of system loops initiating increased thermal bypass inefficiencies because temperature difference is reduced to be dissipated by external means; therefore the engine overheats, rather than the system optimizing, or reducing stress, as assumed alternatives.
