Consider the thermodynamic efficiency of a Diesel engine



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
