First, lets not devolve into nit-picking over technical terms. The question I have is:
Disregarding other factors (such as timing and compression ratio), is the resulting gas pressure (or expansion, since holding volume constant and adding heat causes increased pressure, while holding pressure constant and adding heat causes expansion) of air/fuel combustion caused solely by the heat imparted to the air by the burning of the fuel? IOW, if I just heated up the same mass of air to the same temperature (magically or any other method), would I get the same increased pressure (or volume) as if I ignited a certain mixture of fuel/air?
