|The efficiency of Stirling cycle is equal to Carnot cycle. This is due to the fact that the cycle is reversible and all reversible cycles have the same efficiency.
Ex: Carnot, Stirling, Ericsson.

|What is a Stirling cycle?|
|Shivam said: (Aug 31, 2016)|
|Stirling cycle has less efficiency than Carnot because of heat transfer at constant volume. However, if regenerative Stirling cycle is considered then the efficiency of two is equal.|

How was Stirling Explain?

|Vijay said: (Jun 26, 2017)|
|The Carnot cycle, which is a theoretical rather than a practical cycle, has the maximum possible efficiency of any cycle. There is a theoretical Stirling cycle that is also reversible, which means that it would have the same efficiency as the Carnot cycle. However, neither cycle can be realized in the real world, so a real Stirling cycle will have a lower efficiency than the theoretical Carnot cycle.|

|Nagarajan said: (Oct 7, 2018)|
|Carnot is more efficient.|
|Anupriya Gupta said: (Dec 29, 2018)|
|Cornot cycle is more efficient than sterling cycle.|
|Arvind said: (Jan 27, 2019)|
|But the question is asked in a general case. So the answer should be less than, right?|
|Dwaipayan said: (Feb 24, 2019)|
|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.|
|Ashish Patel said: (Jun 1, 2019)|
|The efficiency of the Stirling cycle is as same as the Carnot cycle efficiency.
Practically it is not that easy to build a Heat Exchanger to operate continuously at that much high temperatures. This is the major difficulty in the Stirling Engines. So these became obsolete after the introduction of an Otto cycle and the diesel Cycles.
|Shivangi said: (Jun 22, 2019)|
|Due to heat transfer at constant volume processes, the efficiency of the Stirling cycle is less than that of the Carnot cycle. But the regenerative Stirling cycle has the same efficiency as the Carnot cycle.|
|Satkar said: (Aug 5, 2019)|
|What is stirling cycle?|
|Utkarsh said: (Aug 31, 2019)|
|For regenerative cycle efficiency of carnot cycle = efficiency of stirling cycle.|
|Ram said: (Sep 29, 2019)|
|That Carnot is more efficient than Stirling.
But the answer is given that both efficiencies are the same.
|Ajay Kumar said: (Oct 26, 2019)|
|- Carnot cycle.
Efficiency = 1-T2/T1.
- Stirling cycle.
Efficiency = 1-T2/T1.
As you saw, the efficiency formula of both cycles are same, so efficiency of Carnot and Stirling cycle is equal.
|Mohit said: (Jan 14, 2020)|
|Carnot cycle is the most efficient one.|
|Venky said: (Jan 27, 2020)|
|If regenarator is used then the efficiency of stirling cycle is equal to carnot cycle otherwise the efficiency is less.|
