If the combustion takes place progressively through a large number of very sma zones of gas and there is no mixing between the zones, determine:

(a) the temperature at -30•‹, just after combustion, of the zone which burns at -30";

(b) the temperature at 0•‹, just after combustion, of the zone which bums at 0';

(c) the temperature at + 30", just after combustion of the zone which bums at + 30";

(d) the temperature of the products in these three zones at + 30". Plot your results versus crank angle to show whether there is a spatial distribution of temperature in the cylinder after combustion. Note: Each small unburned gas element burns at essentially constant pressure and is subsequently compressed and/or expanded. Use charts (Chap. 4) or an equilibrium computer code. The unburned gas state is given by Prob. 9.7.
