Problem
In the Otto cycle, all the heat transfer qH occurs at constant volume. It is more realistic to assume that part of qHoccurs after the piston has started its downward motion in the expansion stroke. Therefore, consider a cycle identical to the Otto cycle, except that the first two-thirds of the total qH occurs at constant volume and the last one-third occurs at constant pressure. Assume the total qH is 700 Btu/lbm, that the state at the beginning of the compression process is 13 lbf/in.2, 68 F, and that the compression ratio is 9. Calculate the maximum pressure and temperature and the thermal efficiency of this cycle. Compare the results with those of a conventional Otto cycle having the same given variables.
