Cylinder conditions at the start of compression in an SI engine operating at WOT

Question

Cylinder conditions at the start of compression in an SI engine operating at WOT on an air-standard Otto cycle are 60 degrees C and 98 kPa. The engine has a compression ratio of 9.5:1 and uses gasoline with AF = 15.5. Combustion efficiency is 96 % and it can be assumed that there is no exhaust residual. The engine is a three liter V6 engine operating at 2400 RPM. At this speed the mechanical efficiency is 84 %. The exhaust pressure of the engine is 100 kPa.

Calculate:
(a) Exhaust Temperature
(b) Actual exhaust residual
(c) Temperature of air entering cylinders from intake manifolds
