The periodic regime of a stable limit cycle for a modified Carnot engine is realized through an algorithmic slide valve. The power, piston oscillation frequency, and efficiency of the engine have been determined in a quasi-harmonic approximation. The modified engine can operate in the regime of a triangular limit cycle (cycles with any number of angles larger than three are realizable). The developed approach to analyzing the dynamic regimes of a Carnot engine allows one to dispense with the concept of entropy.
