Which limitation impacts a real-world diesel engine attempting to achieve ideal Carnot efficiency?

💡 Explanation

Due to the second law of thermodynamics, achieving ideal Carnot efficiency requires isothermal heat transfer, but real-world diesel engines involve finite time, causing the temperature difference, and therefore reduced efficiency. Therefore isothermal transfer at a finite rate limits efficiency, rather than friction, combustion, or perfect insulation that relate to practical rather than theoretical limits.
