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.
