The attached graph gives the pressurecrank angle curve for a spark-ignition engine running at 4 = 1.0. The mass fraction burned x, is also shown. Estimate the tem-

perature of the reactants at a number of crank angles and plot a graph of T, v 8. Assume the reactants in the cylinder are at 333 K and 1 atm pressure at the of compression. It is necessary to make simplifications in order to do this and you should explain clearly what other assumptions you make; they should be compatibl with Prob. 9.8 below.
