As far as your wiki regarding deflagrations, every definition I’ve seen on the word pertains to burning fast or burning violently. None have stated burning uncontrollably or ‘exploding’.
First two articles support your position.....4th articles say combustions "is like an explosion'......3rd article wouldn't open. I can post as many article where the word 'exploding' or 'explosion' never appears in the course of explaining the working of an internal combustion engine. So.....what? You have a point of view and I have a point of view.
For the record, and from my point of view, I do not agree that ignition and burn = explosion......regardless as to what you or the few articles you post may state.
The point is deflagration, which is
what takes place in a combustion chamber, is a more controllable and containable type of explosion. I also do not agree that ignition and burn = explosion
and have never stated so. That is simple combustion.
Here's another mention of explosion. Also from Wikipedia on combustion. http://en.wikipedia.org/wiki/Combustion
..."Rapid combustion is a form of combustion in which large amounts of heat and light energy are released, which often results in a fire. This is used in a form of machinery such as internal combustion engines and in thermobaric weapons. Sometimes, a large volume of gas is liberated in combustion besides the production of heat and light. The sudden evolution of large quantities of gas creates excessive pressure that produces a loud noise. Such a combustion is known as an explosion
You agree that gasoline in a combustion chamber burns rapidly. That it creates a large volume of gas, heat and light. Oh, here's the tipping point...you deny that a loud noise is produced and apparently are unswayable on this point. Well there you go!
While you certainly have a right to your opinion, I remain completely flabbergasted by your stubborn adherence to it.
Take care my friend.
