Task $3$

Part $1$

Determine and then compare the theoretical thermal efficiencies of an ideal Otto and Diesel engine cycle both with a compression ratio of $\backslash (15$: $1\backslash ).$ In the case of the diesel cycle, the cut$-$off ratio is $3.$ Assume the ratio of specific heats for both engines is $1\mathrm{.}4.$

Part $2$

Through your own research, explain why your findings in part $1$ do not represent reality of the efficiencies of the Otto $\backslash$& Diesel engine cycles.
