How about this. I'm going with the book and how FI mimics a carb in every way almost. When a throttle is closed on a carb, does the carb stop feeding fuel out of 3 jet holes? I rest my case. Think what you like. And if that was the case, you'd have some big smile mileage with the miles per gallon, but it ain't happening is it? I'm like walking up to the next chess board, then the next move, and so on to the next table of what I more see as fallacy or how that data is read. Do both of those make sense or not? Either flat out yes or flat the fuck out no. She's not half pregnant. I rest my feel lope pee inn tube.
So the noise on decel is just the sound of the pistons pushing air out? No ignition?
Ignition was at the compression stroke. This noise on decel is like thunder in the pipe. Hot air meeting cold air = Bang. Back-in-pressure goes back in cooler, then meets hot air heading out the exhaust pipe, right? Straight, long, one bend out the heads of a h-d chopper. Backfire like a mother. So the flame front is pretty much done that long down the pipe. About 8 to 9 inches in, the pipe would have this blue color to it. The rest of the pipe was raw, so I would take ATF and wipe it on as it was getting hot and sort of cure the iron skillet. So as I'd see it show up occasionally for service or whatnot, I noticed that bluing and figure the pop is about that much in heat with the oxy adding more heat for that instant pop. I'm not a wave/pressure kind of thinker. Yeah I mess with it, but here is more where my thinking goes. MAG = Heat&ChemRe. Was there heat? Yes. Was there a chemical reaction? Yes. Was there Mag as in noise of a spike in E? Think what you like.
now do you know by not blocking them off you get wrong AFR readings from your 02 sensor in your exhaust
"No, didn't know that. I don't see why. Air is air." ~ Air is air but you mixed it with a chemical. Say a shot glass, 8oz glass, just something you can see thru. Now we pour in oil and water that don't mix. See the water at this level, the oil fills the rest of the glass. That's known as AFR, wink-wink, Oil to Water ratio. It's in the chamber. It's air, and it's fuel, and the intake valve just closed. What is the pressure in the chamber the second that valve closed? Atmospheric pressure or 14.7 = Zero Pressure more or less.
I'm going to shake up the glass, watch all the oil and water mix and keep breaking down the larger bubbles to smaller ones. That's more the mist in the chamber with the valve closed and just being suspended in the air. Of course you are about to compress it so the piston can fly down on the next stroke called the power stroke, so 14.7 AFR becomes packed in that piston dome and cylinder head. The flame front is burning the smaller ones sure, but the big ones flame out and stay a fluid. The expansion of the air shoots the piston back down, the rod comes around to bring the piston back up, the exhaust opens, the piston is coming back up from the other piston that just fired off, sends the momentum in a perpetual pulse of constant AFR, a constant suck of air and on the close of the valve is 14.7 in pressure, or as if you see both valves open with a dead engine and what is the room pressure? What is the pipe inside the non-running engine? And now is not the same atmospheric pressure in the chamber the same number all dead engine?
So the answer in my engine is 14.7 dead engine and fourteen the fuck seven running too, thefuck?! "Who's wit me?" In my best, holding the plastic bag of water and shaking the fish in it... 'show me the money.'
"The O2 sensor doesn't care where it came from just how much there is."
Correct. So say I pour in half water, half oil, what is our AFR now? Not too much fire-off is there? It's still 14.7, the 02 is going to trigger it back to this ideal chemical or neutralize as much oxygen back in the air, not spent fuel about to vaporize and cause poor gas mileage. You cannot create or destroy matter so it don't matter, but tuning does.
and also do you know AFR is determined by engine temp
True. Key on, the temp is known in binary and it now has some lookup table to set the duty cycling rich to start. The higher the temp numbers, the calc keeps shutting off more duty time, or back to base 14.7 AFR if the sensors are in play.
