Your attempt at ignoring the main point of my last post (which I repeated a myriad of times) is noble, but not unnoticed. I will AGAIN post it here for you to consider
Don't worry. there's so much wrong that I'm still considering where to begin!
Even if gasoline fuel burns "slowly" or "quickly", the ignition timing is simply adjusted to ensure the maximum pressure in the cylinder is occuring at TDC.
Yes I did miss that, thanks for pointing it out 'cos that's badly wrong as well! All you'll do is punch a hole in the piston.
You really don't seem to understand timing. I'll try to sum up the key points:
You don't want maximum pressure at TDC because that is very ineffective. Google ineffective crank angle. But the later you time the ignition the less time you'll get to extract work from the fluid before the exhaust valve opens.
And a lot more besides - none of which is about getting maximum pressure at TDC!
You said:
"Flame front speeds have absolutely nothing to do with it"
...and then with a straight face you pretend you know something about timing!
