Everything I've read says that the combustion creates Heat and pressure as if they are completely independent from eachother. What I took issue with was whether the pressure which powers the engine is a form of energy released by the exothermic reaction, or if it is only caused by the rapid heating. But some sources I have read say that a combustion reaction will only ever release energy as heat or light. Pressure is not on that list so I guess it must be as you say.
