Which outcome occurs when a Stirling engine decreases internal regenerator matrix surface area?

A)Reduced thermal energy transfer efficiency✓

B)Increased engine operational lifespan

C)Lower engine compression ratio achieved

D)Improved pressure vessel structural integrity

💡 Explanation

Reduced regenerator surface area limits heat exchange during the Stirling cycle; because the mechanism of heat transfer decreases, thermal energy regenerates less effectively, therefore engine efficiency drops, rather than increased lifespan from lower operating temperatures.
