    Consider the expansion stroke only of a typical air-standard Diesel cycle engine which has a compression ratio of 20 and a cutoff ratio of 2. At the beginning of the process (fuel injection) the air temperature is 627°C, and the air expands at a constant pressure of 6.2 MPa until cutoff (volume ratio 2:1). Subsequently the air expands adiabatically until it reaches the maximum volume. Using ideal gas properties of air at 1000K, determine the: (a) temperatures reached at the...
