The hose that is drawing the gasoline vapors out from the jar has to be on the top of the jar, the second hose that introduces fresh air into the jar has to be on the bottom. It would be good to add some obstacle (filter) in front of the first hose to block the liquid gasoline from entering into the engine's intake. Also the gasoline from the yank must be shut down!

My next step will be to tie into the fuel line with a "t" and run a line to my vaporizer through a needle valve so I can regulate the amount of flow to refill the vaporizer while the vehicle is running. The car has a 10 gallon tank and my goal is to able to drive to a town almost 400 miles away on that ONE tank. Much more experimenting is to come but with less than 40 dollars invested a 16 mpg gain is great!

The advantage is the much lower consumption (100-200... miles/gallon, Shell mentions in a video even thousand miles/gallon). HHO is pretty dangerous but is surely duable, but it reduces mainly emmissions only (around 70%).

@raptor731 There are 2 hoses connected to the jar (not clearly visible in the video...). The hose that is about 1 inch above the gasoline level is drawing air into the bottle (air enters the jar on this hose), and gasoline vapors are exiting on the hose that is on the cap of the jar. ...and thanks for the support :)

@Sixdouble5321 thanks for the suggestion !! I have to do some more experiments!

@2220Blues I tried once to add the fog of a humidifier to a 2 stroke engine's intake.. but there was no visible change, and I did not tested it enough. By adding hot steam that helps to clean the exhaust smoke visibly as I saw others.

@tampicokeed Today (and in the past), liquid gasoline is mixed with air, and only a part of that is vaporized. The engine was revved at around 2:42, 2:50, and also the video is cut. Plus the air + fuel ratio is uncontrolled in this setup.

@bayman50cal There are 2 hoses attached to the glass jar. On one hose air enters to the bottom of the jar (bubbling the gasoline), and on the second hose the gasoline + air vapors exit into the engine.

The car in this video uses vapor only (gaseous state of matter), carbs and injectors introduce sprayed/atomized liquid gasoline droplets into the engine. In order to control the mixture in relation to the load, you just push the acceleration a little bit more. The engine already draws the vapors, no need to pump it and draw it too. Part 2 of this video uses heat from the radiator fluid to warm up the liquid gasoline.

@MrBry329 it already has an LPG (Liquefied Petroleum Gas) system on it !

@diesel5355 I'm not sure yet, but I think it's the opposite. The engine started only later when the gasoline got colder and vaporized less than before. Also the air-fuel ratio was not controlled, but actually very little fuel is needed to run an engine, that is visible in the video "2 Stroke Engine running on gasoline mist only (with 600 Watt load)" around 1:45, or in "2 Stroke Engine running on gasoline vapors only (with 600 Watt load)".

@zaprodk If the pressure increases than the temperature rises (like the diesel ignition), if the pressure drops than the temperature drops also.

@AmeriCIA that requires a modification of the exhaust pipes... some holes or something... so I haven't tried yet

@goodmechanic There are 2 hoses connected to the jar! On the first hose (that goes to the bottom of the jar) air enters into the bottle, and on the second hose (which is on the top of jar) air and vapor exits the jar. At 1:38 the bottle cap is taken off, it's behind the jar, there it is visible the second hose which is connected to the bottle cap. At 2:16 there are also visible 2 hoses on the jar. So liquid gas is not being siphoned via tube submerged in gasoline.

@Sixdouble5321 Theoretically an internal combustion engine works best when gasoline is well vaporized, and not in a liquid state... but it needs to be tested and adapted to the vapor fuel and not the liquid one!

@tampicokeed it's running on vapors only, which is more efficient than on liquid gasoline

@bustfer07 I'm not sure... but I guess it doesn't matter as long as the vapors reach the engine...

@furulevi at 1:38 the bottle cap is taken off, it's behind the jar, there it is visible the second hose which is connected to the bottle cap.

@FarceTheory the engine draws the gasoline vapors whether they are heavier than air or not... that's what the engine is running on from 2:03 and later...

@RutinaRottis I'm not heating the gasoline in this setup... but it is still better with vapors than on liquid gasoline

@goodmechanic This setup is not running on vapors?

@chotomato I hope more than on liquid gasoline... still needs some testing...

@bubba110775 an ultrasonic mist maker is good... but not when is cold outside... :(

I find this type of work very interesting, and would be ready to get into doing this type of experimentation on a spare vehicle if I had I one to spare. I'm a skeptic by nature, but I do fid it interesting to see that multiple, and un-related, people have gotten vehicles to do this sort of thing. Granted, they're not driving down the road or tearing up a track, but it is promising to see that with more work/building a motor just run on vapor. Check out Smokey Yunick's work.

@skylarker7041 valve life will not be reduced if you use a clean gaseous fuel instead a liquid one which favors carbon deposits...

some addition to my statement: carbs feed sprayed (or atomized) LIQUID gasoline droplets into the engine, and SOME of that turns into vapor due to heat or low pressure, and that is running the engine, but carbs or injectors are not feeding vapor into an engine at all as stated by MrRichinil

This idea is not new... it goes all the way back to the early 1900's. The bubbles need to be as tiny as they can be. My bubbling box had an air manifold underneath with a piece of sintered bronze that lay right on top of all the small holes that I drilled. The air traveling through the sintered bronze aerated the gas into a foam. also inside the box were interlocking baffles that provided for one inch columns of gas to keep the sloshing down to a minimum. The box was as big as a car battery.

@davidevgen if it works on vapor than it should consume much less, watch the movie 'gas hole', it says 149 miles per gallon, that is a consumption of 1.57 liter per 100 kilometers, in 1947 !!! ...and the car was not light at all

Yes it is, there are 2 hoses connected to the glass jar, both into the cap, so the ingoing hose is not really visible from outside.

what's your method to vaporize well the liquid gasoline?

hi, really view all your videos, very educational to me. Thanks a lot my friend. I did it to my bike honda 100cc, and worked great. Some questions? Morning starting right up, going to road, after 2 km, it start sputtering,and fuel getting very cold, like ice. Does that mean that i should always try find a way to heat it?

than why some older cars had 100-200 miles / gallon?

Great video, what is the gas mileage like on it and has it increased over liquid gas? Probably should stick an air filter onto the intake nozzle so the gas doesn't collect dirt and stuff. And i was thinking of using hot engine coolant to kind of heat the gasoline, having the air and fuel separate and then kind of have a vapor sucked in by the carburetor. then adjust air/fuel ratio and now u can daily drive it that way. May need liquid gas still for morning start-up as engine temp still cool.

there was a metallic mesh placed on the hose when the engine was running on vapor, and there was no explosion..., the air/fuel ratio was not controlled at all in this setup

@xoxoXoieoxox check the history of vapor carburetors, example: 149 Miles per gallon in 1947 (1.56 L/100Km) from Shell on a "Studebaker" car, and many many more... (Pogue, Tucker, Ogle...)

The driving is in part 2 of this video called "Car running on gasoline vapor only (2 of 2)". Is in the description. The car also has an LPG system, so gaseous fuel is no problem for an engine, it runs just fine. It's not too easy to measure the consumption because modern gasoline does not vaporize that well as the old ones, or at least in this setup is not working well enough. Maybe with much more heat (from exhaust) it would evaporate better.

FYI. I also hooked-up a set of Exhaust Gas Manifold Temp Gauges (aircraft) to see what the temps were. With the standard carburetor in place, the temp was 850 F. With the Beam dry gas carburetor the needles sat on the pegs (750 F). It was getting an ideal mix and no CO. The oil would have stayed pretty clean too as there would have been no choke to start the engine and hence no soot to dirty the oil.

@csmiron into the gasoline? it will not evaporate as fast as the gasoline... but the engine will still work.

Furulevi, this was a good demonstration. I built a small vaporizer for my 95 Toyota Corolla and was impressed with the results. The added fuel vapor causes the O2 sensors to read a RICH fuel environment and to decrease the amount of pulses to the injectors decreasing the amount of fuel used. After my calculations and a nice test run, I determined that I had gained 12 mpg! I was happy to see a nice increase in mileage and no discernible detriment to performance.

@xoxoXoieoxox just the air filter is in that thing

Have you tried using exhaust gasses to pre-heat the jar and vapors similar to a GEET setup?

@obieezx11 ...this is the first attempt on this engine, I didn't wanted to blow it up with lots of gasoline vapors ;)

@goodmechanic 1. Gasoline is shut off; 2. LPG is shut off; 3. Liquid gasoline is not escaping from the jar into the carb; Than on what fuel is the engine running?

the yellow VW was running on gasoline mist from an ultrasonic mist maker, not gasoline vapor... I haven't yet done fuel consumption measurements using vapor only...

It is vapor only (transparent & invisible), it is not soaking/flooding anything, the air-fuel ratio is the one that is not too perfect.

Admisia motorului trage vaporii de benzina dintr-un borcan si astfel motorul este alimentat doar cu un amestec de aer + vapori de benzina. Daca benzina din borcan ar fi incalzita atunci motorul ar functiona in continuu, in momentul de fata se raceste excesiv si abia se evapora, iar motorul se opreste in timp. Consumul masinii utilizand doar vapori de benzina ar trebui sa fie mult mai mic ca si utilizand benzina pulverizata prin carburator sau injectoare.

The movie "Gas Hole" shows some tests related to this. Shell broke even the 1000 miles/gallon barrier, and I guess it wasn't on liquid gasoline...

@FarceTheory this is not a Geet system, just a simple vapor carb imitation...

A carburetor (or injector) does not really vaporize the gasoline, it just sprays it or atomizes it, that is mostly liquid and only a small portion is turned into gaseous (vaporized) state. In this setup only the totally transparent and invisible gasoline vapor is drawn into the engine.

You Sir are spot on Smokey was my guru when I first started in the Performance field many years ago and have run a Gasoline Tractor without Carby (old one broke ) so I made a Vapor producer but the biggest issue was controlling the actual mixture , the same was happening here too. Carbs are simply better than vapor for this.

@Olcsvary84 Jobb lenne angolul irni... mert maskepp kommentalasok lesznek belole hogy nem ertheto mindenkinek ;)) Megtakaritast nem tudom meg, nem kiserleteztem tul sokat egyelore vele, de gondolom joval kevesebbet kellene fogyasszon ha gaznemu benzinnel mukodne. Etanollal nem probaltam de benzin es viz-el probaltam a kis generator motran. Film neve: "2 Stroke Engine running on gasoline mist only (with 600 Watt load)".

@goodmechanic Normal carburettors and injectors only spray the liquid gasoline, this one uses the gaseous state (vapor) of the gasoline to run an engine. Here is an example: kzread.info/dash/bejne/fqipmqtvYciyk8Y.html [Difference between liquid and vaporized (gaseous) gasoline]

super tare frate ... felicitari !

you're right... it is like the "vapor lock"

Your bubbler hose has a smaller diameter(3/8), that means that the air that enters the jar will be blown with greater power, try vice versa using the 1/2 hose as the bubbler hose, and the liquid gasoline should not rise as high as with the 3/8 hose.

it is not only idling (2:42, 2:49), I didn't tried this engine under load, but a smaller one I did (2 Stroke Engine running on gasoline vapors only (with 600 Watt load)), but other inventors drove their cars many many miles on vapor, which was some load...

@raptor731 Did you read your post and think about it before posting it? Do you know anything about internal combustion engines? Do you know anything about the 4 known states of matter (solid, liquid, gas, plasma) and their relationship to each other? Go hold the carburetor on a hot engine that has a good phenolic spacer and you'll notice the carb is cold. "Buddy" I have over 27 years experience building engines. This technique is used to start/test old junkers that are in need of a carb rebuild.

There is no element in the glass jar which could create fine gasoline particles ("mist"), so the engine is drawing only gasoline vapor. This car was also tested using an ultrasonic mist maker. Car is running on mist at 3:33 in this video: kzread.info/dash/bejne/aWFluKh9l5iYnco.html

I like your scientific approach. Perhaps figure out a way to add battery powered heating (appropriate heating), to the gasoline jar. Maybe an electronic controller that reads the temperature of the gasoline, everytime it drops below a certain point it heats it up and everytime it reaches a certain temp it turns off the heating. To keep a balance of the right temperature you need. Nice work!

No 92 ford f250 with a 460 motor 2wd model i had to mod alot so i could shut off ecm and still keep it all working right after market dist so it could spark with out the ecm on and give better controll over the spark timing and i had to do a few other changes

I liked this video, it was cool and fun to watch. Backyard science rules the world!

@raptor731 Gasoline does evaporate when left unsealed. All I was telling furulevi is that the amount of fumes/vapors coming out of the jar was not enough to sustain the engine and that the liquid fuel was interring the carb. Therefore his setup was not a working vaporization system, but actually a crude carb. He already figured that out quite obviously, but you still don't have a clue.

you are right... liquid gasoline does not burn, but that does not mean that carburetors or injectors are introducing vapors into the cylinders... the problem is that only a small portion of the liquid gasoline turns into gaseous state (vapor) and only that part does something useful, the rest is waste and pollution...

@goodmechanic by the way, just so you know, any liquid at a lower atmospheric pressure boils at a lower temperature, so a vacuum over gas would make it boil at a lower temperature. increase that vacuum enough and it would boil at room temperature, sadly, this is not whats happening in this video

@kremene Raspund in engleza sa inteleaga mai multa lume (altfel o sa commenteze sigur careva ;)) I haven't done any other experiments regarding this experiment, but it should work under load too (I think) because the engine rpms went up pretty easily, about the fuel consumption on vapors only... I don't know yet...

-doar cu vapori are putere, vezi partea a 2-a (watch?v=SZQCSKEUAmg), numai trebuie nimerit raportul aer/combustibil; -"furtunul de intrare a benzinei in carburetor" ...am uitat, dar la 1:23 se vede ca nu porneste

Part of the unburned fuel is neutralized, transformed, converted into less harmful compounds. The term "burnt" is not too correct because there are no flames inside the catalyzer.

@TK42138 Yes it will increase if you add heat to the gasoline !!! Just take care, because lots of gasoline vapors near you = fire or booom :)

I haven't done much research lately in this domain... it is cold outside :) haven't measured the mileage yet either...

@furulevi ive alway thought running any thing on vapor instead of strait gas would work better. and last longer

@furulevi Watched your vid again. Did notice two hoses in jar. The hose submerged in gasoline is allowing air into the jar. The gas is being splashed onto the sides of the jar/all over(in droplets) by engine vibration. The incoming air assists in doing this by blowing the gasoline. The hose leading into the carb has manilfold vacuum pressure that pulls the atomized fuel into the engine. Once again a crude carb and not a vapor system. You're half way there. Ad a hot plate to VAPORIZE the gas.

the carburetor is not adding only vapors into the engine cylinders like the bubbler jar does

theories... Daniel Dingel, Stanley Meyer drove their cars on water

Maybe in the end of the video is 28 to 1, because in the beginning the mixture is far too rich, that's why the engine can't start. (Richer than the theoretical 14.7 to 1 stoichiometric ratio)

Gaseous fuels like propane, LNG or LPG (in this case) are not ruining any components(valves), both liquid and gaseous fuels are burned inside the engine, but liquid ones favor much much more carbon deposits, which could lead to deterioration. Propane, LNG, LPG are already in gaseous state not liquid when they reach the engine(at least in this carburated car).

@furulevi BTW whats that big motor looking thing the glass jar is siting on some kind of generator or maybe some kind of elaborate horn ??? XP

liquid is coming out from the exhaust, and that is not just clear water from condensation or from the burning

Yes youve improved on over a century of automotive engineering evolution just by dumping some gasoline into an old pickle jar,and jamming an old garden hose into it!! How nice. Theres got to really be some psycosis involved in this situation.

salut ... vroiam sa te intreb cum accelerezi dak lpg ii scos? datorita aerului care trece prin borcan,formeaza vapori care sunt trasi de carburator in motor. dar dak u nu dai benzina si nui dai nici lpg cand calci pedala de acceleratie cum popate motoru sa se accelerese sa poti misca masina din loc,intrantaia intradoua?

@Cohunnamatta The gasoline definitely requires some more heat, the fastest heating would be through the exhaust but that is too hot, through the coolant liquid it is too slow for winter time, electric is not good enough for the battery in winter... needs more research...

@furulevi I heard about this issue of the vacume causing the Gas temp to drop an in a metal gas tank the tank would actually decompress. But What I was thinking to rectify this issue is a pressure activated intake valve that would decompress the air in the gas tank while not letting out the gas vapor. Have you tried this train of thought at all? i don't have to funds to make a working prototype but In theory I haven't been able to find any real issues.

@furulevi Pjckac1 gave you one of the methods for turning liquid gasoline into a vapor. Take note that heat is used to do this. Raptor731(anti-support) said that your fuel was "boiling." Well, it's not.Gasoline depending on chemical make up boils at 100-400 degrees F. With the open setup you have there the escaping vapors would ignite. You have no heat source on your jar. The gas is being shaken by engine vibrations. Liquid gas is being siphoned via tube submerged in gasoline. Last post to help.

@furulevi dose it work any better than a carb? O.o they do the same thing

theoretically that sounds good because it will crack larger molecules into smaller ones via the exhaust heat... but adding warm/hot air-fuel mixture into the engine will boil the cooling water quickly!!

You're right here, I forgot that one, but at 1:22 it is visible that the engine is not starting anymore. The car is used on LPG not on gasoline, so the gas tank is empty.

Thanks for the link! :) Shell did some good research on fuel economy, but that doesn't mean they tend to apply that knowledge in todays vehicles. The Buick Roadmaster (from the movie Gas Hole): - had 2025 kg, not a few hundred pounds; - had a 5 liter V8, not a small engine.

@goodmechanic well I'm glad we cleared up the confusion. the last point you are not understanding is that, according to the laws of physics, evaporation is a cooling process. How else do you explain the cold jar (or cold carburetors)? gas is evaporating, denying this is silly. You do not always need to bring a liquid to a boil to evaporate it, or else an ocean wind would pick up no moisture. SOME of the liquid evaporates, because SOME of the molecules have more kinetic energy than others on avg

If you can find Tom Ogle Guinness record I'll buy your 100 year old technology. There is no Guinness Record and no documentation or Tom Ogle's carburetor. Urban Legend

Its still doing the same thing. I'm a new setup with 1/2 for the bubbler hose and intake vacuum hose and theres still the whirlwind and the gas in my jar is suck out. I even cut the bubbler hose shorter and it does the same thing. I'm gonna try a different port, which is a smaller diameter but I know my car probably will not idle good.

there is a huge difference between 100% gasoline vapor (like in this video), and some gasoline vapor + a lot of liquid gasoline droplets (like carbs or injectors)

Salut!Imi place mult experimentul tau!Spune-mi merge si in sarcina sau doar la relanti?Cat consumă la relanti într-o oră?

@furulevi Jee i know, but 100 years ago they gasolin wasn't so good quality so they have to boost that vaporizing prosses with heat.

@goodmechanic yes I did make that mistake before I realized that the 'siphon' you are talking about was really an air inlet, as air is being drawn in it splashes the gas around. The real vacuum input is very hard to see, see my other comment

Do you or anyone you know sell plans on how to create this type of setup for even a novice? Thanks so much! I've been looking for some one to accomplish something like this for a very long time.

The car gets its fresh air at the carburetor, because the hose in the carb is only covered with a cloth, it is not air tight. Visible at 2:17, when the cloth is squeezed a bit, the mixture becomes too rich. The bottle has 2 hoses, one is not too visible...

Correct, but that does not mean that all liquid gasoline is turned into vapor.

Gasoline should not be atomized but vaporized in order to considerably reduce consumption and emissions, some cars did that already and the worked/work very well. Injection is not the best way to introduce fuel into the engine, but is good for starting the engine because the fuel and the spark are in the same close location. Mixing correctly the fuel with the air is harder in a small place like the interior of the cylinder.

During my testing I fill the vaporizer unit with 16 oz. of pure fuel. The addition of the bronze filter gives increased vaporization and for the same drive, 40 miles, I am getting a consistent 15 - 16 mpg gain. However, I am seeing as much as 10 ounces of usage from the vaporizer as compared to 8 ounces before the filter. I believe I can adjust the flow valve to correct this.

old heavy car: 1946 Buick Roadmaster; weight: 4480 lbs (2032 kg)

-when it has a good air-fuel ratio, than it revs up decently (at 2:50) -only the vapors burn not the liquid, that is moving the 2000 pound load -injectors are not vaporizing the gasoline, they are creatig mostly small liquid doplets
