Which consequence results when a heat engine experiences exhaust backpressure?

💡 Explanation

Backpressure forces exhaust to do more work. Less net work is done by the engine's piston because pressure increases; therefore efficiency suffers, rather than producing more power under ideal Carnot conditions or reducing component wear.
