I get a lot of terrific ideas from those II believing comments in fact
I read thousands comments each week looking for future video ideas one of the most interesting video ideas
I received today is to see if I can get a small engine to run off of nothing other than just gas
Vapors it just seems to me that if this idea will actually work
Met car manufacturers would have switched over to running vehicles on gas vapors many years ago instead of running off of liquid gas
After all according to those leading comments if I can get an engine run off of gas vapors
It'll save lots of fuel in fact instead of an automobile getting say 20 to 30 miles per gallon in
theory an automobile could get hundreds of miles per gallon, so
Rather than to question whether this is possible or not I say we get this project underway and find out if it'll work
So I want to airtight seal so all I'm going to do is apply
This jb weld around the threads and also I want this to back out
So I'm gonna apply the jb weld around the threads
And I'm gonna just screw this on in there
And again, I want this to be airtight so what I'll do is just dip this in the JB well
All right, this is the fuel line that goes from the tank into the carburetor. I'm just going to put a bolt in it
And I'll block this off
So there's absolutely no fuel that's gonna be traveling into this engine
This is keep air from getting in there as well
This is the crankcase ventilation so as this engines running if I can get it running
It's just gonna probably push out a little bit of
Smoke nothing to be concerned about we'll just leave this where it'll vent into the atmosphere
So the way this gas vapor setup is supposed to work the engine creates a vacuum
that's how it draws fuel into the engine and with the vapor set up as the
Engine is creating a vacuum that draws air down these two pipes and into the fuel
Now once the air reaches the fuel it creates a bunch of bubbles within the fuel which turns into a vapor that vapor then travels
through this single line pass this valve and into the engine itself and
The purpose of this valve is to regulate how much vapor enters the engine again
I don't think this is going to work, but we're going to give it a try okay
We'll see if this thing is going to run
I move this entire setup outside the shop just because I don't want this thing to catch my shop on fire if this canister explodes
So let's give this a try
Okay, I ran using for about a hour and a half on this fuel it did go through some fuel what's interesting is the color?
Of the fuel seems to have changed it seems more yellowish than before, maybe it's just instill oxygenated
Maybe there's still air inside the fuel itself from all the bubbling action so what I'm gonna. Do now. I'm just really curious
Do I actually get better economy out of using the vapors or what I get just as good of economy running?
Just the liquid through the engine
so I'm going to do now is dump out this old fuel and I'm gonna start off by adding one pint and
Timing to see how long the engine will run?
And then I'm gonna go ahead and put the fuel tank back on and run it with one pipe and see how long it'll run
On straight fuel to see if there's any difference
So I ran into singe in about twenty-seven half minutes what I'm going to go ahead
And do there's still some fuel left in here that the tubes aren't long enough to agitate the fuel enough
so I'm go ahead and measure how much fuel I have left and then measure the difference and
Add the exact same amount of fuel to this same engine using a gas tank to see how long it'll run on that much fuel
Alright, let's see how much fuel I used
Twenty-seven half minutes looks like it. It's about an inch off the bottom of this container maybe about an inch and a half
So the amount of fuel left is
Indicated by the blue tape line that you can see
And so what I'm going to do is when I add fuel of the fuel tank
I'm going to stop adding when I get down to that level. I'm going to go ahead and dump this fuel out
Okay, I'm gonna fill a fuel up to the same line that we did before
I'm not gonna add all this fuel just to the blue line and then I'm gonna stop
The few levels right we're at the top of the tape is at so this is very close
This is going to front within a fraction of an ounce this should be good enough in terms of there's any
significant difference in fuel consumption between vapor and running a liquid
An engine running on nothing other than fuel vapors the Hat is unbelievable
I really did not think that was that would work. I have to admit
I was totally wrong I came into this video a total skeptic and now I'm a believer
I was really surprised though that I didn't get that much better fuel economy
But as far as claims of saving four hundred to five hundred percent on the fuel
I just don't see that happening, but you know I'm not saying anyone else is being dishonest about it
It's just that I just did not achieve those results. Maybe there's something that I should be doing differently
Anyway, I wouldn't have done this video how to not Bend for the hundreds of people asking me to do it
I spent hours each week reading and replying to your comments. I hope you'll take time to give me some more video ideas
I've got a long list of video projects ahead of me, and they're pretty exciting you guys recommended them
so we're gonna see what's gonna happen with each and every one of them and
Just want to say, please leave a comment
I hope you'll like subscribe and share this video until next time, please take care, and I look forward to seing you there
