M0 is called the clearance steam and M is called theworking steam, steam supply or boiler steam. CYCLE OF STEAM ENGINE Fig. 69 then represents the theoretical form of cycle used onthe steam engine. It is known as the Rankine or Clausiuscycle although the former name is employed at times for thecycle shown in Fig. 71. The difference between the Carnotcycle and the Rankine cycle is that in the former cycle theworking substance is supposed to be in the cylinder and heatonly is added, while in the latter substance is added and with itheat. On the Carnot cycle, if represented by Fig. 68, the qualitychanges from that at 4 to that at 1, growing greater, while itdecreases from 2 to 3, hence 1-2 and 4-3 are not similar adia-batics. For the Rankine cycle the quality on 4-1 is constant,the variab
