Which consequence reduces the efficiency after short-cycling a Stirling engine approaching ideal Carnot efficiency?

💡 Explanation

A reduced regenerator matrix temperature gradient limits heat recapture; short cycling disrupts the ideal temperature profile. Therefore efficiency drops, because the regenerator's effectiveness is diminished, rather than issues related to compression or expansion.
