8-1. A six-cylinder SI engine, with a compression ratio of rc= 8.5, operates on an air-standard Otto cycle at WOT. Cylinder temperature and pressure when the exhaust valve opens are 1000 K and 520 kPa. Exhaust pressure is 100 kPa and air temperature in the intake manifold is 35°C.
Calculate:
(a) Exhaust temperature during exhaust stroke. [0C]
(b) Exhaust residual. [%]
(c) Cylinder temperature at the start of compression. [0C]
(d) Peak temperature of cycle. [0C]
(e) Cylinder temperature when the intake valve opens. [0C]
