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
