    Air in a cylinder-Piston device undergoes a cyclic process. Initially, the air is at P-5 [MPa) and T-350 [C]. Process 1 to 2 is an isothermal expansion from 5 (MPa) to 1 [MPa). Process 2 to 3 is a polytropie compression to 5 [MPa) with a polytropic exponent n=1.3. The cycle gets completed by a constant pressure process from the state 3 to 1. Air properties are R 0.287 [Kj/Kg. K] and k=1.4 and the mass of air in cylinder...

    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...
