- In this video, we deep dive into how to make a hydrogen carburetor that will fit most small engines from 50cc to over 300cc
Made from an LPG carburetor, it is simple and easy to make. This is not the best way to run hydrogen gas, but it is the cheapest and easiest. The added benefit of keeping the governor is fantastic for petrol generator conversions.

Hydrogen powered go kart about to go hard
That’s the plan, supercharge or turbocharged?
@@Hydrogenguys supercharger to keep it compact and linear
@@Dannyt1997 will most likely end up going down that route, would sound pretty ace too.
@Hydrogenguys looking forward to watching the build
This man is not suicidal
😂
What is this shit posted an hour ago but 2 day old. Comments whta a laugh lol
Thank you for the time and energy that you have spent bringing this to fruition.
My pleasure, Thank you very much
I work for a fuel systems company that is deploying hydrogen fuel systems to some of the biggest manufacturers in the world, mostly for mid sized trucks and buses. We obviously use a modern electronic controller, electronic fuel injection, electronic managed turbo and etc. We also help our customers design & calibrate the engine and by now have loads and loads of learnings in the fascinating world of Hydrogen Internal Combustion. I have loved watching this video and the engine teardown one as well, many of your observations are very pertinent and I commend you for obtaining so much good knowledge on such low budget. The thing I love is that your carburetor functioning principle relies on one unique factor that is pretty unique to hydrogen: you can run very well by changing the air/fuel ratio. A lot of spark ignited engine technical people have spent all their careers trying to keep air fuel ratio fixed, so they never realize that hydrogen engines can be run by changing load by changing lambda. This would be more of a lean burn/diesel kind of mentality, except that diesel people do not understand spark timing at all. So yes, I do not know if your carbie is designed like that on purpose but, from my own standpoint, it is very smart because it benefits from the fuel properties. My only negative comment would be to say that if I understood correctly, you expected very rich combustion to be low NOx. Actually it is the other way round and it is well documented in the scientific literature that to reduce engine out NOx, you have to go seriously lean. In the other video you mention EGR. I cannot wait to see how you work on that and how it sorts itself out. From my experience, get ready for a LOT of backfires. Awesome job mate 🙂
Wow, sounds like you have my dream job,
Thanks for the compliment and info, i will look into the lean mix and Nox relationship again, the documents I read explained running overly rich resulted in less air/nitrogen in the combustion chamber and less heat resulting in less Nox emissions… along with water injection to further reduce internal temperatures and Nox. I will read up on this again.
Love your work in the electrical fuel injection field. Electric direct injection with forced induction is the way to go for sure.
Amazing man thanks for sharing !!!
Glad you found it useful
In its intended usage, this is a carb.
As you are using it, this is NOT a carburetor. A carburetor turns a liquid fuel into a combustible vapor via vacuum induction into a venturi.
This is gas injection. The carb is just functioning as a throttle.
Brilliant design!
Glad you like it!
Perfect explanation thanks Brudda 🎉
Glad you found it useful 🫡
Mate! I'm making a hydrogen generator that will produce enough hydrogen to run that generator, you've probably guessed that I'm taking about free energy from water. Split cell so hydrogen and oxygen is already separated.
Wouldn't it be fantastic if we could all power our homes with water and for extra gas we add potassium Hydroxide.
Free energy at home and free travel ❤️🙏
Free until you turn every part of metal to flakes....
Let's GOOOO! I'm so excited
Just run hho in two lines, one hh and another with Oxygen. You can also use 91% + alcohol with a vaporizer to make a fog inside a bucket and run a hose to the carb with a small valve 12mm or so to adjudt the mixture, also heating vegetable oil until it smokes without oxygen and pipe it into the engine. It should run. If the spark was hot enough. If the crank case vent is piped into the engine can possibly help with valve seat wear, also the heating wood or vegetable scraps, dried and sealed inside a metal container and heated to produce fuel, the exhaust can be used for the heat. With a 75-100mm ,x 300 mm tubing with a 25-35 mm exhaust pipe running through the center with each end capped with thread on plugs to seal the fill and clean out ports. Wrap with header insulation to hold in the heat. With it mounted 70mm from the engine. Even candle wax can be a fuel also. Then nearly anything can be fuel. Wood shavings grass clippings, anything including possibly vegetable oil, just allow it to heat without air, but vented enough to not explode TV alternative fuels are cool. The Russian huys turned rubber tires into fuel, so plastics maybe used also . Possibly with HHO also.
Wow, i wonder if this can be done on any carbureted application
Most likely, very simple to do.
Hi, your videos a really really good and appropriate them very much, please could you do a video of how to adjust the ignition timing for the GX160 generator engine to top dead centre so the engine doesn’t end up with piston knock…
Is there a simple solution?
Thankyou, 100%. I’ll make a video explaining how to do it some point soon, I basically made a crude bracket that moves the magneto up towards top dead centre
@@Hydrogenguys Thank you for replying, I really appreciate of how to deal with that issue
I believe that the parts suppliers for racing go carts would have something for that.
Very cool. How would you get it to work in a bigger application? Are those carbies easy to get?
Just scale it up, you can can LPG carburettors for all the Honda GX range engines I think, so same principle but bigger carburettor.
And yes the carburettors are easy to find, and relatively cheap too.
Thankyou for the comment
You’d have to use a turbo or supercharger in a few through setup to keep vacuum on that regulator I guess. Supercharger might be better at low revs.
100% with the engine rebuild I’d like to look into supercharging.
If you haven't already, you should apply for a patent on that carburetor.
Sorry, but I was curious about the tube with the spring around it and the on/off switch at the regulator portion. I may have missed your explanation about those parts. What are they for?
I don't know why u have that air filter as from my knowledge (aviation mechanic) i can say that bigger paper filter will have same airflow restriction as this thing, and definitely will have better filtering capabilities. Also i know how even dust affect parts that rotates fast, in that case reduplicate.
Awesome video thank you for posting. If I'm understanding this correctly u are linking the throttle and choke together at the same time? I'm game to try converting my ford 2600 tractor to hydrogen if you'd be interested in discussing it more w me.
Assuming its gas/petrol. 3 cyl. carb. I would assume if you looked up a carb of a forklift with a similar 3 cyl. motor. and make the same. OR... you just run Propane. Should be easier to obtain and is cleaner than gas.
Would running a turbo eliminate the vacuum needed for operation?
Would running a fuel injection system be more efficient than a carburetor?
Yeah fuel injection and forced induction is the way to go
@@Hydrogenguys Would a smaller carburetor comparative to engine size be better? Like a small 2 barrel on a v8. This is similar to what @ThunderHead289 did with a lawnmower carburetor on a v8.
I will do my own
and I will put your channel on it if its work
feel free to use this video as a guide to get you going :)
How do you store your hydrogen? Im worried about embrittlement so i havent started my system yet
I currently buy the gas in a pre filled bottle, it makes for more consistent engine testing. But check out some of my older videos where I make pure hydrogen gas and store it in an air compressor tank. Just make sure there is no oxygen in the tank before filling and make sure the gas your filling the tank with is 99% pure hydrogen.
Prefill with water 🤔🤷🏼♂️
@@B.Cote39 vacuum the tank
Not new.. Been playing with gas LPG for 30+ years but cost of your fuel source will dictate what fuel you run.. liquid hydrogen ain't cheap.. anyone can make brown gas with the understanding of how water is split.. but most will get tired of tuning the system to reach an acceptable level of economy.. LPG loves to run hot for best efficiency a great summer time fuel for long running..
Yeah it basically works the same way as LPG, just a basic modification to the carburettor to make it run well on hydrogen gas instead
@@Hydrogenguys still relates to cost of the fuel and containment vessels.. running a 351ci on hydrogen would not be economical and with the clowns jibbering on about climate change need to re think their whole life choices.. we need Co2 and Nox to fuel plant growth.. humanity is fucked in the curent trend.. so drive on with the dirty fuel and pollution the plant matter will still thrive.. end of the day the planet will heal itself and Humans will not be around so it matters very little what we do..
you guys forget about a few important things , hho needs far higher air to fuel ratio yes, you got that part right. But hho gas also burns much faster than petrol , this means your gx is running on much too slow ignition timing. you need to eeither alter the keyway on the magneto flywheel... or better yet , make an addjustable mounting bracket to mount the coil on so you can move the coil (radially) closer or farther from TDC. let me share a secret , hho expands rapidly on combustion(steam) but also shrinks again as it cools , very gast... this is enhancing scavenging wich is not benificiary in your setup coz the gas is cut off after the intake stroke so scavenging cannot work ... fix all your problrms by switching to diesel , using hho as an additive instead of trying to use it as a sole fuel source. hho likes higher compression but wont combust under compression like diesel does,,,diesels are allready very efficient so you can improve on it ten fold ,,,as for engine running on hho alone ...if it was easy and good , then we would have had water engines in evrything long ago , as for storing hho ...NO!!!! do not ever compress any fuel/air mix into any tank coz if you do , you have actually made a bomb ! you dont want a bomb connected to an ignition source or else you will die ! it getsgeneraated on the go, wich poses another challenge, how? gotry making a diy hho gen that can produce enough gas per minute to run a I.C.E !!! thats my findings so far on my mission. Use it, dont use it. just dont blow uoyour house ok.
Hi Thankyou for the comment and concern, this channel is about pure hydrogen gas not so much HHO, so storage isn’t a problem as no oxygen is present, as for the ignition timing, extra heat and fuel ratios that’s all in over videos, this video was just about the hydrogen delivery system.
I’m currently filming a new set of videos where I disassemble and rebuild an engine specifically for pure hydrogen or HHO mix, this will include the timing changes. will be released in the next week or so.
Thanks again

i understand that by product of hydrogen is water. what modification do you propose to remove water.
it just blows out the muffler.
Benzene also produces water. It's a hydrocarbon after all.
H2O and CO2. It's why water comes out of the tailpipes of cars.
Dose the carb work well on HHO?
Yes, in theory it will work but will require a healthy engine with good valves to stop backfire, I mention it at the end of the video.
Hope that helps.
So your sacrifice power for lower NoX... hhmmm not sure i like that.. wonder how you can tune it to eliminate NoX and get full power.
Direct injection, but you will get high Nox, so would need a catalytic converter, and water injection to bring it down to acceptable levels.
@@Hydrogenguys Yer i seen that you said in the video about water and i thought "ay did he just say water in an angine" lol i was always told water in engine = dead engine so i need to learn more about that side it seems.
@@RaithUK too much water is very bad, but a fine mist is actually quite good for engines, it cools the incoming air and reduces the chance of pre detonation, so you can run more power,
Have a search for ‘water methanol injection’ that will help :)
Nox is created at very high temperatures around 2500°F In the presence of oxygen and nitrogen. Keeping the combustion chamber below that temperature will keep from creating the Nox.
Water injection is a good way to accomplish that, which will also help keep the inside of the engine clean, and if the droplet size is correct, it can actually turn to steam during the combustion cycle adding power and efficiency.
Typically increasing the compression ratio will help with power, and efficiency, but will increase the temperature inside the combustion chamber. Then you can use water injection to bring the temp back down.
@@johnwyman6126nice info, cheers.
Will be building a dedicated hydrogen engine soon, higher compression, water injection, higher heat resistant parts, hopefully moving to forced induction after. Can’t wait!
Won't that mean that the exhaust gas contains unburnt hydrogen? Sounds inefficient and also the exhaust might back fire?
Not exactly no, the hydrogen should all be burned still but not at stoichiometric ratio, so less power output and less efficiency. This is a simple set up really.
@@Hydrogenguys How does that work if you are sealing off virtually all of the air flow?
@@Drenovit’s not a true seal so air/oxygen still passes the choke valve.
why use piston engines at all, use turbines or fuel cells.
I set up the channel to show how petrol engines that are currently in use around the world can be converted to run on hydrogen gas, to be more environmentally friendly, instead of replacing them, And to reduce waste.
Now the aim is to try and build a performance engine for motorsport.
For economy and efficiency hydrogen fuel cells are best especially for power generation and transport industries,
Turbines are awesome! Would love to build one after this next project is complete.🤞
We have so so so many piston engines rn it'd be way easier to use what we have
@@Enderbro3300 its easy to carry millions of years of burden by just tradition excuse. oh well, change happens fast when it comes.
@@Enderbro3300 oh right, they can be used as melting metal cast stock, for the new turbine engines
@@Enderbro3300 I dont mind piston engines in general, but with turbo complexity you should just use the natural breathing piston engines or go directly to many many times more powerful turbine engines.
Intelligent presentation. But.. (please do not take offenc)... please explain why I had to stomach a TMOBILE ad before watching? I was nauseous through the entirety of your video. IF you can't IMMEDIETELY refresh your audience after they are subjected to the torture of advertizing then you will NEVER make it. God bless you.
Sadly ads are the only way of funding the channel, shame I can’t pick something more interesting. Thankyou for the feedback though will keep it in mind.
There is essentially no need for a carburetor. Everything can work without throttle. There is an acceptable minimum percentage of hydrogen content (approximately 10%); anything higher will burn. So, it’s enough just to pipe into the intake tract and make quantitative adjustments.

Yes very true, but this set up means the gas pressure can remain the same throughout the rev range, meaning it’s perfect for generators or engines with a governor, the pressure can be set and the carburettor will do the work adjusting the rpm.
