Which operational hazard emerges when a Sterling engine runs too slowly?

💡 Explanation

Backflow occurs because lower speeds reduce the buffer pressure differential when the working gas cycles; volumetric pumping is reduced, therefore gases leak past the imperfect displacer rings, rather than maintaining efficient forward flow.
