To review the efficiency of ideal heat engines operating on the Otto and Diesel cycles, you are asked to perform the following branches: • Provide general plot(s) for thermal efficiency, 7 vs compression ratio, r for ideal Otto and diesel engines and show the typical compressions ratios. Compare your plots in terms of the typical compression ratio values. • Using your plot of the thermal efficiency, 7 vs compression ratio, r for ideal diesel engine, show how will the thermal efficiency of the diesel engine, n would change with the cut-off ratio values. • Explain mathematically how the thermal efficiency, n of Otto cycle is always higher than diesel cycle if-and-only-if both engines are operated at the same compression ratio, r.

Question
To review the efficiency of ideal heat engines operating on the Otto and Diesel cycles,
you are asked to perform the following branches:
• Provide general plot(s) for thermal efficiency, 7 vs compression ratio, r for ideal
Otto and diesel engines and show the typical compressions ratios. Compare your
plots in terms of the typical compression ratio values.
• Using your plot of the thermal efficiency, 7 vs compression ratio, r for ideal
diesel engine, show how will the thermal efficiency of the diesel engine, n would
change with the cut-off ratio values.
• Explain mathematically how the thermal efficiency, n of Otto cycle is always
higher than diesel cycle if-and-only-if both engines are operated at the same
compression ratio, r.
