Why Do Different Methods Yield Different Efficiencies in a Reversible Cycle?

[QUOTE="TSny, post: 6123204, member: 229090"] Good question. When people say that "all reversible engines working between two given temperatures have the same efficiency", they are talking about cases where heat is transferred to or from the engine only at the two given temperatures. In the example with the isochoric process, the temperature of the engine will continuously increase as heat is added during the isochoric process. So, the engine will take in heat at temperatures intermediate between the two given temperatures. This cycle has less efficiency compared to a cycle where all of the heat is added at the highest given temperature. [/QUOTE]
