Question: A marine diesel engine has a compression ratio r = 18 and a cutoff ratio r c = 2.5. The intake air is at p

A marine diesel engine has a compression ratio r = 18 and a cutoff ratio r_c = 2.5. The intake air is at p₁ =100 kPa and T₁ = 300K. Assuming an ideal cold air standard Diesel cycle, what is the engine’s efficiency? Use the ideal and adiabatic gas laws to determine the temperature at points ➁, ➂, and ➃. Compute the work per cycle. What is the power output of this engine if its displacement is 10 L and it runs at 2000 rpm? What is its fuel consumption per hour (assuming the energy content of diesel fuel to be 140MJ/gal)?
