Adiesel cycle has a compression ratio of 16 and a cutoff ratio of 2. at the beginning of the compression process, air is at 95 kpa and 27°c (300 k). remember the processes in order are compression, heat addition at constant pressure, expansion, heat removal at constant volume. if needed the ideal gas constant of air is 0.287 kj/(kg-k). use air standard analysis to determine: a) the temperature after the heat addition process (k) b) the mean effective pressure (kpa) c) diesel engines are known to be more efficient than gasoline engines. from a compression ratio aspect why are diesel cycles more efficient?
