Consider the thermodynamic efficiency of a Diesel engine. Using equation (2.73) of your
textbook, plot the efficiency of this type of engine for injection ratios ρ between 1and 5
(incrementing by 1) at compression ratios ε of 18, 20, 22, and 24. Note that this is ηth vs ρ
plot at the stated ε values. Describe your observations. Use MATLAB to plot the graphs
