Which outcome results when a heat engine's exhaust pressure increases beyond design?

💡 Explanation

Reduced work output happens because higher exhaust pressure decreases the pressure differential driving the pistons, impacting the engine's efficiency from reduced temperature-gradient energy conversion during expansion, rather than stalls or thermal runaway under normal operational stresses.
