Which outcome results when exhaust backpressure increases during an internal combustion Brayton cycle?

💡 Explanation

Increased exhaust backpressure raises the exhaust temperature, therefore reducing the temperature difference across the turbine. This reduces the overall cycle thermal efficiency because the expansion ratio decreases, rather than providing any improvements to fuel or compressor performance.
