text: The limiting factors are the temperature at which the heat enters the engine, T H {\displaystyle T_{\rm {H}}\,} , and the temperature of the environment into which the engine exhausts its waste heat, T C {\displaystyle T_{\rm {C}}\,} , measured in an absolute scale, such as the Kelvin or Rankine scale.
text: The limiting factors are the temperature at which the heat enters the engine, T H {\displaystyle T_{\rm {H}}\,} , and the temperature of the environment into which the engine exhausts its waste heat, T C {\displaystyle T_{\rm {C}}\,} , measured in an absolute scale, such as the Kelvin or Rankine scale.
text: Examples of T H {\displaystyle T_{\rm {H}}\,} are the temperature of hot steam entering the turbine of a steam power plant, or the temperature at which the fuel burns in an internal combustion engine.
text: It can be seen that since T C {\displaystyle T_{\rm {C}}\,} is fixed by the environment, the only way for a designer to increase the Carnot efficiency of an engine is to increase T H {\displaystyle T_{\rm {H}}\,} , the temperature at which the heat is added to the engine.
text: Practical engine cycles are irreversible and thus have inherently lower efficiency than the Carnot efficiency when operated between the same temperatures T H {\displaystyle T_{\rm {H}}\,} and T C {\displaystyle T_{\rm {C}}\,} .
text: The Carnot cycle achieves maximum efficiency because all the heat is added to the working fluid at the maximum temperature T H {\displaystyle T_{\rm {H}}\,} , and removed at the minimum temperature T C {\displaystyle T_{\rm {C}}\,} .
