In the theoretical machine that Sadi Carnot used to describe his ideal cycle, the hot and cold sources must act alternately in the same place, which seems technically unfeasible. The use of two cylinders and two heat exchangers makes it possible to imitate this machine, but induces friction and dead volume.
