Home Made Gas Vaporizer

[Gillettetg]

Hello guys, I been reading this forum for a while now to find answers to my questions. But now it seems I have a unique question.

I built a home made gas vaporizer out of a paint can and lid and a couple half inch pipes. I removed the air filter box and made a little box to bolt to the MAF sensor I then drilled two 2" holes in the side of the box. And two 3/4" holes in the top of the box. I used the small holes to attach two 1/2" pipes from the box to the lid on the paint can. I also drilled 2 more holes in the paint can lid for vent pipes. So basically its like a bong. Only the water is gas.

I have an obd2 device that reads real time data. The system is effecting things. I can tell by my ltft and stft percentage changes. Sometimes I get -20 on ltft and 5 on stft. But sometimes I get -3 ltft and 40 stft.

The 02 sensor reads very low .050 ish when stft is 40. When the 02 sensor jumps to .800 ish the stft is -3 is and will sometimes go to -20.

Sometimes the ltft will be -10 and the ltft -8 and sometimes the ltft will be -23 and stft will be 3.
It bounces around.

So does the computer change something based on ltft that effects stft?
So like if ltft is -20 for 3mins does the computer make that a new normal and then move the number ltft to 0 so the stft can do the adjusting?

At this point I am just guessing at what this stuff means. All the info I can find only talks about troubleshooting. But I have introduced fuel vapors into the mix so I know my sensors are all good. I noticed that the numbers of stft and ltft stay more steady when the system is set up like normal. I have really only notice small gains in mpg.

So.... You made a bomb?

Welcome to this forum! Some members on this site have water/hydrogen separators on their vehicles. One member dyno tested it, and didn't see any improvement. I'm sure that it did something but nothing substantial. There was a lot of interest in it a few years ago when gasoline cost more.

So what's the purpose here? Make the truck run rich? Seems counter productive

Simply people trying to out engineer engineers. There's no such thing as free energy

That's right.

There have been absolutely NO engineering advances since 2001; your vehicle is perfect they way it is even though it was built to a cost point and designed for the middle of a mass market.

And therefore can't be improved upon in any way at all.

Well it won't run rich. The computer monitors and adjust the ratio in real time.

I did some gas mileage testing and it has not effected the gas mileage. Either I don't have it set up properly or the computer is fighting it by not leaning enough. I am not getting any codes though so it must not be having to lean the fuel to much.

I was really rather just looking for info on what the long term fuel trim readings might mean. Like the questions I asked above.

I believe this is effecting the way it runs and I believe it can be seen in the readings. But I don't have a $75 mpg gauge. I am certain my refueling and counting miles is accurate enough though. The last two tanks I only got 12 mpg. The tank before that I got 20mpg. I believe that was mostly highway. So I have not improved milage at all. This is all over youtube. So I figured I would try it. After all it only cost $30 for parts. I never really took good notice of mpg before I started this experiment. So I think I will put it back to stock and study the ltft and stft readings. If any one comes along that can take a stab at answering my questions it will be appreciated.

Here is a picture of what I built. If it worked I planned on putting a flame arrestor in.

I put it back to stock and never got a -20 on long term or short term fuel trim. Things settled down quite a bit. I think what was happening is that it purculated the gas and created fumes which got sucked out and it was not consistent enough so it would get rich and the computer would lean out the ratio. But shortly after the fumes would get weaker and the computer would have to add fuel again.

A few times when installed it would show -24 on long-term fuel trim. If I could get consistent fumes then theoretically I could improve mpg by 20%.

I have also looked at HHO and making a generator don't look to difficult. But I would need probably $200 of blow money to do that experiment. There are people running their truck on, on demand HHO generators only. Meaning no gas at all. Which is cool. But I wonder how much water it takes to get 300 miles.

There are also people to using 3 gal buckets and running their cars with no fuel pump. On fumes from the bucket alone. They claim to get 240 mpg. But they sacrifice lots of power. I didn't want to do this way because its to weak.
