@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 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!
@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.
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 :)
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.
@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)".
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 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.
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!
@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...
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...
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.
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
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).
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.
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.
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.
@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.
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.
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...
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!!
@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.
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.
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...
@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.
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...
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
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.
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7-1VFDg52mg.html
Thanks... Some heat would be good, just take care the gasoline vapors not to escape into the atmosphere, because it is highly flammable and dangerous! If you lower the pressure on your gasoline container/tank, that will also cool the liquid, but also evaporate it at a lower temperature. Gasoline nowadays has lots of additives in it so it won't evaporate too easily.
"All cars that run on gas run on gasoline vapor." Correct, but only a small portion of the liquid gasoline is turned into gaseous state (into gasoline vapor), this is the problem. Vacuum does lower the temperature of gasoline, and also lowers the boiling point... thus turning it from liquid state into gaseous state. Otherwise the car wouldn't start only on liquid gasoline when you pull the choke valve.
the engine is 1,3 liter only (0.34 gal)... it is kinda sufficient, the problem is the gasoline vapor, that has to be sufficient, it needs a heat source also
@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
Cand apesi pedala de acceleratie defapt deschizi clapeta de acceleratie in carburator, clapea odata deschisa motorul trage mai mult aer si vapori de benzina din borcan > mai mult amestec de aer+combustibil = acceleratie. Motorul cand merge la relanti defapt ii cam franat de faptul ca clapeta de acceleratie ii 99% inchisa. Cand pistonul merge jos (si clapeta de acc. ii 99% inchisa) defapt in cilindru ai vacuum!
-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
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.
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!
-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
Vapors/O2 are what internal combustion engines run on. When cold, gasoline releases less vapors. Extra fuel (rich mixture) is dumped into the combustion area of a cold engine to increase the volume of vapors. After engine starts, combustion area temps instantly vaporize the interring atomized fuel mixture requiring less liquid fuel to achieve the proper vapor/O2 ratio. This ratio is determined by many factors (engine,carb, ect.). The same applies to fuel injection. Keep trying and learning.
No, they are run of gas particulate (if you are using a carburetor or injectors), that only burns at 20% efficiency. If you vaporize the gas, you get closer to 80% efficiency. The more air you block off the better it works, this was not the best way to block out the airflow around the hose so it was not getting enough of the vapors. It gets enough air through the vaporizer...
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)
Sweet! Just keep in mind that todays gasoline wont vaporize completely... It is full off additives, even anti vaporizing additives, so you won't be able to use all of it by vaporization. In part 2 of tis video I had the same problem, when it had gasoline in the glass jar but it was useless the car would not run on that, because the most volatile compounds were already used after travelling a few kilometers.
@furulevi No it is not. At 1:11-1:45 engine starts to run rough and die because it's no longer receiving enough liquid gas to sustain itself (running lean). At 1:45-2:00 the engine didn't start because the liquid gas hadn't yet traveled down the tube into the carburetor. When the engine starts the agitation of the jar assists in atomizing (liquid into droplets) the liquid gas to achieve a burnable air/fuel mixture. Gas vaporization is a doable thing. But, this isn't an example of it.
@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.
I mean how much gasoline evaporated from your secondary reservoir which was the glass jar in my case, not the car's tank? Please check if the mileage gain is constant on your trips! :) 16 more miles per gallon is great !! ;)
Your thinking is correct but you are not taking into account the phase change between liquid and gas. An atomized fuel is still mostly liquid. However, if you take a gallon of gasoline and heat it enough, you end up with a phase change to a gas from a liquid. The expansion in volume that takes place is massive, yet the BTU value of the fuel does not change. Furthermore, emissions are reduced to very low levels compared to injectors. This has been proven time and time again.
@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.
@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.
@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...
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)
@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
If more than 98% of the gasoline is burnt, than explain these: -how did some old and heavy cars reach hundreds of miles/gallon? -how did Shell broke even the 1000 miles/gallon barrier?
I'm not trying to get out more energy from gasoline than 100% (as you are saying), I'm trying to use more energy to run the engine, and less energy to waste from that gasoline. Internal combustion engines have an efficiency of around 20%, so I'm trying to get 30-40-50...%. Don't think that conventional science will teach too many useful things!
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.
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.
proof of concept is excellent.. now for some proper fitting, safe equipment to run this properly. warm the vapours using a reroute of the coolant into a 2nd box and then run the warmer vapours into the 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
@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!
today, it stopped working, so i just added a new cup of gasoline, and it started right on. I need to measure with a small 250cc jar, how many km it goes with normal fuel in carb, and then add 250cc to the vapor tank and mark with pen before and after position, and again measure the km. If you have any result about the economy please tell us. I saw your videos with the VW beatle working 30 min, but i didn't see how fuel it consumes normal way. Thanks for your nice work, i learned a lot.
Hmm :) that's interesting... So you left the original fuel delivery system untouched, and only drew some gasoline vapors into the engine? How much gasoline evaporated from your reservoir? Because that fuel also cost money...
Hello, do you have backfire problem ? The sound of the engine indicates that air fuel mixture is not right and it sound like you do have some backfire sound.
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.
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?
If I remember correctly, Smokey Yunick had a car/engine that ran on pasteurized gasoline in the early 1980's. It may be important to remember also that all gasoline ICE would be gas vapor engines as the fuel will not burn as a liquid.
fuel atomization = "liquid droplets in a gas" (wikipedia - Atomization) You really think that no small liquid droplets are entering an engine? That would mean that all cars are already running only on gasoline vapor and not small liquid gasoline droplets... That would mean that we are all getting hundreds of miles / gallon... At least my car is not that fuel efficient !
Very little fuel gets wasted if the engine is in good working order and in the case of fuel injectors, if it's port injection, the computer works in conjunction with the emission system and only feeds the engine the amount of fuel needed, if by chance it isn't all burned in the cylinder, then it is burned in the catalytic converter so there is no raw fuel leaving the tail pipe.
Kate Savers that isn't the percentage which isn't burned though, that is the pecentage of the energy converted into kinetic energy (which is more like 18%) the rest of the energy is converted into heat (~80%) and a very small percentage of fuel is actually unburnt (like 2-5%). Some petrol engines put exhaust gas back into the intake but this isn't specifically designed to burn the unburnt fuel (although it does help with reducing emissions), it increases efficiency because it reduces the vaccume preasure inside the intake which means the engines looses less energy on the intake stroke due to having less vaccume to fight against (diesel engines don't suffer from this problem because they don't have any valves restricting the intake air)
furulevi look fuel-efficient-vehicles.org/energy-news/?p=1310 sorry look www.unicusmagazine.com/pioneers2003/firestorm.htm "I had the car running at 40 to 1 air-to-fuel ratio".
You are right. But as soon as the fuel enters the combustion chamber (sometimes even before if the engines hot enough) the heat from the engine will vaporize the fuel. Therefore, no need for fuel vaporizers haha
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.
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.
That is a rather unique reaction that occurs with petrochemicals and liquid oxygen. Congratulations! You found the exception, however, it is possible that the liquid oxygen coming in contact with room-temperature gasoline causes the oxygen to flash to a gas, pulling the gasoline with it and making a sort of plume which then ignites.
I put in about 16 oz of pure unleaded fuel and in 40 miles it only used approximately 7 - 8 oz from the reservoir. I did a retest today without the system being active and the car gets about 23 mpg. After I added a valve to regulate the air flow and a bronze filter for better vaporization, I was able to increase the mileage to approximately 39 mpg! A 16 mpg gain! This is being done on a 1.4 liter engine in a 95 Toyota Corolla with 148k+ miles on it.
