Question: Assume that an SI engine has the following parameters : displacement (V 1 V 2 ): 2.4 L; compression ratio 9.5:1; air to fuel

Assume that an SI engine has the following parameters : displacement (V₁ − V₂): 2.4 L; compression ratio 9.5:1; air to fuel mass ratio 15:1; heating value of fuel 44MJ/kg, pressure at start of compression 90 kPa, intake temperature 300K. Compute the pressure, volume, and temperature at each of the points ➀, ➁,➂, and ➃ in the idealized cold air standard Otto cycle. Compute the work done per cycle, and estimate the engine efficiency in this idealized model. Compute the power at 3000 rpm.
