An Otto cycle SI engine with a compression ratio of has peak cycle temperature and pressure of 2800 K and 9000 kPa. Cylinder pressure when the exhaust valve opens is 460 kPa and exhaust manifold pressure is 100 kPa.
Calculate:
(a) Exhaust temperature during exhaust stroke. [°C]
(b) Exhaust residual after each cycle. [%]
(c) Velocity out of the exhaust valve when the valve first opens. [m/sec]
(d) Theoretical momentary maximum temperature in the exhaust. [°C]
