>Due to breakup of medium to large hydrocarbon molecules in a gasoline engine, the number of particles increases there too. Also, formation of water molecules results in a single O2 molecule becoming two water molecules.
Typical reaction:- 2C8H18 (octane) + 25O2 => 16CO2 + 18H2O 2 + 25 => 34< Robin thanks for posting the reaction taking place in a typical gasoline engine. I realized that a small increase to the total number of molecules would occur, but if you consider that most of the gas molecules within the system are nitrogen, then that increase is not overly significant. I guesstimate the total increase is less than 10% when burning the fuel. With the Papp process I am suspecting more like a 100 % change...is that too optimistic? >Stirling engines don't have an exhaust either do they?< That is a good point. In a normal ICE a large amount of heat escapes the system along with the exhaust. The Papp device does not seem to suffer that loss from what I understand. But, always keep in mind that the Papp engine might not be real.

The pressure increase as a consequence of this heat is likely to far outweigh the doubling of pressure due to ionization. (I haven't run the numbers, so I could well be wrong here.) Consequently, I would guess that the whole ionization-recombination process happens near TDC, and is responsible for the primary pressure pulse in the engine. ...snip Interesting....
