For the pressure data in Fig. P9-7, assume auto ignition occurs at 10 crank angle degrees after the top center position. Determine the maximum pressure reached in the end-gas after knock occurs. From the mass fraction burned and approximate average burned gas conditions at this time, estimate the volume occupied by the end-gas as a fraction of the cylinder volume just before auto ignition occurs. Use the charts (Chap. 4) or an equilibrium computer code.
