Any engine using the Carnot cycle, which uses only reversible processes (adiabatic and isothermal), is known as a Carnot engine While Carnot engines are ideal engines, in reality, no engine achieves Carnot's theoretical maximum efficiency, since dissipative processes, such as friction, play a role.reversible engine is correct.

No engine working between two given temperatures can be more efficient than a reversible engine working between the same two temperatures and that all the reversible engines working between the same two temperatures have the same efficiency, whatever the working substance may be.

Reversible Engine Efficiency
The Carnot cycle has maximum efficiency for a reversible engine because it is based on idealized assumptions that are only achievable in a reversible process.
Carnot Cycle Efficiency
The Carnot cycle is a theoretical thermodynamic cycle that consists of two isothermal processes and two adiabatic processes. The efficiency of the Carnot cycle is calculated as the ratio of the work output to the heat input, which is given by the formula: Efficiency = 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir.
Reversible Process
In a reversible process, the system undergoes changes in such a way that it can be returned to its initial state without leaving any trace on the surroundings. This implies that there are no irreversible losses during the process.
Maximum Efficiency
Since the Carnot cycle is based on the assumption of a reversible process, it represents the upper limit of efficiency that any heat engine can achieve. This is because reversible processes are idealized and do not involve any dissipative effects such as friction, heat transfer through a finite temperature difference, or fluid flow resistance.
Therefore, the Carnot cycle has maximum efficiency for a reversible engine because it operates under ideal conditions where all processes are reversible and no irreversible losses occur.
