Which performance outcome of a jet engine increases closer to Carnot efficiency?

A)Higher exhaust gas temperatures
B)More efficient fuel combustion
C)Greater ratio of compressor pressure
D)Reduced turbine blade erosion

💡 Explanation

Closer approximation requires improved heat transfer, therefore a greater ratio of compressor pressure achieves a greater temperature difference following Carnot cycle principles, rather than altered exhaust temperatures because those change due to turbine load.
