Rework Problem 9.25 except that the compression ratio and cutoff ratio are, respectively, a) 16 and 2
b) 20 and 1.75.
Heat is added in the amount of 800 kJ/kg of air to a diesel cycle with a compression ratio of 19 and a cutoff ratio of 1.8. Air enters the engine at 100 kPa and 27°C. Determine, using a cold-air analysis:
i) The temperature and pressure of the products of combustion at the end of the combustion process
ii) The thermal efficiency of the engine
iii) The specific work output of the cycle
iv) The mean effective pressure
