Only when regeration is employed. If the heat rejection during constant volume process is consumed wholly in the heat addition (also const. Vol) process, needless to mention, both being reversible, then the area under heat rejection curve and that for heat addition curve are congruous. This will give the efficiency [1-(T2/T1)]. T2 the lowest temp of the cycle and T1 the highest one.

But the question is asked in a general case. So the answer should be less than, right?

Cornot cycle is more efficient than sterling cycle.

Carnot is more efficient.

Stirling cycle less efficient than carnot cycle but if regenerative reversible stirling cycle is used then the efficiency is equal to carnot cycle efficiency.

Stirling cycle efficiency would be equal to carnot cycle efficiency, when there is complete (ideal) regeneration of heat being rejected at costant volume process.

Both are ideal cycle, so the efficiency also same.

Carnot cycle is equal to Stirling cycle when temp not considered in this case.
