This is awesome man and we need more content like this on SEworld. Kudos to you for releasing free. I am developing car parts that I am also putting free out there to the public I think it's a good movement!! Keep up the wicked work!
brilliant work!
Love from the netherlands! Your a legend
On a rotary? But they have literally no valves. What's your thinking, what is your plan?
Oh, and this is about 11 levels of awesome, as are you.
Put the relevant piston to top dead centre put an air line onto that cylinder and pressurise it that should hold the valve up then make your self a lever bolt it to one of the studs and compress the valve springs and remove the collets on re-installing you may have to lift the valve a little to get the colletts back in I have done this on many different engines try this if you were going to take the head off anyway if it does not work for you then you have not lost that much then go ahead and remove the head it is worth a try.
"This!" I love that you're still doing the Doug demuro thing
good job bro
I am exited to see what people can do with this technology, and for the technology from a over 2 million dollar car to be brought out for everyone to use is incredible.
An radial superchager i think could be made for the air supply just so theres no annoying piston kompressor noise.
POP UP UP AND DOWN HEAD LIGHTS
Your an incredible person, smart as heck. You done this, from a vision to an actual working concept. Your so amazing don't short yourself on your brilliance.
This is so incredibly cool. If I was you, I don't think I could stop myself from constantly blabbing to everyone about freevalve.
I can highly recommend Volvo XC90/XC60 pneumatic air compressor. OEM No. 31441864 to drive the system. Cheap and easy to get running - And low noise.
Dosent konegsegnhave a Patten on this ?
" Van Down by the river" Matt Foley
This is the type of engineer I hope I become.
I just watched a dude light a fire with an oxyfuel cutter... interesting
Amazing job!
Hello, is there any way I could get the code and cad? Looking to see what language it is written in, Thanks
Ahh the classic broken Mazda dipstick of the 90s and early 2000s. Same thing happens to every replacement I get for my Protege.
for the love of god never give up on this its so freaking cool and the possibility's are almost endless...but have you thought of solenoids off a abs unit they are easy to get and rather easy to function on command
Motorcyles, cars, open wheel race car, awesome hardline water-cooled pc on the wall, and does Arduino stuff? I've found my new favorite channel.
Hang on does this man have his pc mounted on the wall
New subscriber!
No music more talking. Can’t learn anything from crap music
You’re gonna be living in a van down by the river!
You are awesome!
I think this is the first ever car project involving a Miata that had me genuinely interested! lol Fascinating stuff, I'll be watching this development with intreague.
im trying to do this on my old hatchback
Respect he couldve gotten millions probably
SO could i use the variations to swap between fuel type? like hho n gas or propane?
Not all heroes wear capes, but you certainly can. You've earned it.
Firearms design has many locking mechanisms which would allow the use of less powerful solenoids.
Algorithm blessed me today, two of my favorite types of content engineering and miatas lol.
How much better horsepower & torque are you getting and where do think you can take performance?
I believe the weakest link is maintaining enough air pressure, this system take A LOT of air.
Thanks for the video. Look at Alan milliard’s videos-he keeps them nice and short, great for keeping the interest levels are up and getting a good overall understanding of the mechanical project. Just a suggestion…
The fact you did this all and made the research free really shows you care about the technology. This was really interesting and I could see the glow on your face when it actually worked. That's crazy and awesome! Hopefully free valve will be more electrical and magnetic in the future, but I love the design idea
You or someone needs to start a forum, I'd love to try adding this to one of my engines
The shaft on your lathe is bent.....
Commenting for algorithm
Open source has way more potential than isolated companies trying to figure out things by themselves. And imagine the potential once A.I. starts designing technological solutions in ways we can't fathom yet.
Nice clean shop.
I don't understand why thumbs down 113 times!
Good work
I write this text in the comments with hopes that this blows up!
Very cool video
Thank you so much for posting all the info! I have been thinking about doing this to a car and that would held tremendously!
Probably better to make it free to not get in trouble with Koenigsegg...
Ive always thought a reed valve of sorts on the intake side no control what so ever like what a air compressor has it will always inhale as much as it possibly can it will stay closed on the second down stroke because of combustion someone smarter may be able to sit down think of the pros and cons
Absolutely incredible. Not only in the design, and construction but also in the working product. I respect the time it would have taken to tune this system, and for you to then put it up for free, that’s inspiring. Keep up the revolutionary work
Wouldn’t a higher operating voltage and capacitors help with speed and force? I don’t think solenoids would work because it’s 1 or 0 and you really need a stepper style setup or an analog 0-20 signal to control stroke length and overall timing.
So realistically you could run open ports from the cylinder head and control timing of the valves instead of using a throttle body to control air.
This is awesome, well done!! Considering LS engines are only 2V and they respond so well to cam timing changes, would be a fascinating application!
You figure out how to put valves on a rotary....... and ill poop an apex seal
I thought you'd use the belt to drive a compressor.
Cool video. Thanks! Is there any data on the high rpm threshold yet? As cool as the project is for it's own sake, my primary interest is in seeing how fast the engine can spin. In the kind of racing that I do, it would be a huge advantage to increase engine speed, especially if torque doesn't fall off too badly. Currently, valve springs and their irrascible tendency to bounce around limits our engine speed. Going to air actuation fixes that problem in a hurry! What are you doing about oiling? Are the oil ports for the cam blocked, restricted somehow, left open? And is there anything to keep oil on the valve stems? Or do they run dry (which is common). Solenoid control is something I have wanted to play with for a long time. I hope it works! Heat seems like it will be a problem. The pneumatic system is essentially self-cooling, and energy is put into the system by the compressor in the trunk. With solenoids, there is no air flow to carry the heat away, and all the energy is transformed into electromotive force right inside the solenoid. I was concerned that there wouldn't be sufficient time for saturation in a solenoid system. But that's probably not an issue at sane rpm's. In the old days, a good engine builder could get 7,000 rpm out of an eight cylinder engine, and the ignition coil had to saturate four times per revolution. So it seems like a solenoid that only has to actuate once every two revolutions should have plenty of the to saturate. Also, it's premature to ask the question, but have you considered a two stroke variant? With the ability to jigger the valve timing free of the cam, it seems that if there was a supercharger on one of these engines to provide a constant pressure on the intake side, the valves could be programmed to both open up at the bottom of the power stroke, allowing exhaust to be forced out, and fresh fuel/air blown in before the piston heads back up. The position of the exhaust valve isn't ideal, but if it would work at all the gains in power and efficiency might outweigh the problems. Great work! Thanks again! And if you want to apply this technology to an opel cam in head engine, hit me up! I'll give you one.
This is amazing! Glad you decided to make it free for anyone to use. The bummer is some car manufacturer will run with this and make billions, possibly trillions from your idea.
This is genius. This would be would be way nore popular if it was put in a 2jz or more popular crate engines.
I talked with Christian at the IMTS in Chicago about Freevalve in '95 or '96. It's a necessary technology for Jocko Johnson's PowerRring engine design to work properly. It still needs to be scaled down in size a bit for that application. I love that you're sharing your work for the greater good. Do you have any plans to show off your work in AZ? I recognized a few places you drove by. It'd be cool to see it in action.
With control of the vavles I wonder if this could become into a sparkless skyactiv x type setup that just uses pressure, that would be insane to combine both.
awesome project can wait to see where it leads
incredible video. Just saw the article on The Drive about how you made this all open source. so many people would have patented this or sold it as a kit, but it's extremely cool you made it available for free. You just gained another subscriber, keep up the amazing video's!
The possibilty to change the character of the engine mid-drive via software is pretty crazy technology
Awesome build buddy, I remember Lotus messing with this kind of tech about a decade ago, think they might have based it off a Hydraulic system iirc, but its great that nowadays there are readily available parts and controllers that can be bought off a shelf and adapted to the purpose in your garage.
This man's a crazy genius
nuts
Man thats a nice shop
This man about to catch a cease and desist from Koenigsegg
This is a pretty spectacular home engineering feat 😯
You should be doing R&D on Rolls Royce Jet Engines
2 months? Impressive mate, please keep it up!
Very interested in how well this works on a rotary. Should free up 1000hp on a 13B 2 rotor for sure. They have so much losses and restriction from their valves its ridiculous.
Yeah the possibilities this opens up is endless. I can’t wait to see how this tech is applied to forced induction and maybe a car that can take an octane. And in the Avenue of efficiency, the machine learning idea could be crazy too.
Wow what an inspiration. Cant wait to see you advance with this in the future!
Okay so hear me out guys Ford Straight 6 Two-Stage Turbo Freevalve Yes? No? Am I dead yet?
I’ve only just came across your channel and subscribed to you after literally 2 minutes of the first video I watched. I’m currently doing my degree in mechanical engineering and I hope to be able to achieve something like yourself at some point!
Don't let money get in the way of tech, first person I've ever heard have the same opinion as I do on that. Profit has crushed innovation so many times.
I get how the design works, I just don't understand the purpose. Is this for greater efficiency? Less wasted horse power on moving a mechanical valve drivetrain? Or does this have some kind of latency advantage over mechanical drive and springs? Actually curious, I have no idea why you did this.
Golden SEworld... Thanks so much for posting
If you were to run a supercharger, could you pull compressed air from that to actuate the valves? If not, could a belt driven screw type air compressor provide sufficient pressure and volume to run the engine up to redline for extended periods of time? Could a surge tank be added to smooth pressure surges or drops?
Hats off sir for your appreciation on that almost impossible project!
A very simple grass roots way to have a fantastic air compressor to drive the system would be an AC Condenser. People retrofit them all the time on old Jeeps for on-board air. Works great.
@konisegg fly this dude out for a tour of the factory! cool stuff man!
Not a '92 unless it's been in a wreck and had the front bumper replaced with a '93-97 model...
Need more people like you in the world 🙏🏆
Really awesome man! I hope that this becomes a reality for enthusiasts
I'd be hesitant to try to do this on a rotary, based on the idea that they don't use anything close to a classical valve system like you see in a piston engine. I haven't been in the Mazda ecosystem for a while, but when I worked on RX-7s back in the mid-90s, they were all run on reed valves. I'd be interested in seeing a really beefy setup like this for something like a carbureted GM big block. I feel like technology like this would be much more compact than the large hunks of metal that currently manage the valve systems in pushrod engines.
Yes
Instead of a compressor, could you use the exhaust to somehow run the system?
I love it!! Amazing work.
Nice try, but the idea isn't new. I worked this principle on a single cylinder moped engine 30 years ago, but abandoned the idea, when I realized I couldn't switch from 4 to 2-stroke mode. Bosch has been working on solenoids for this application for decades.
you are one talented ass smart dude! this is the most interesting/cool thing ive seen done to a miata yet
Amazing, but have you considered using an air-conditioning pump to feed air to a tank in addition to an air compressor, I've seen alot of offroading guys use the aircon pump as a compressor for on the trails, maybe you could utilize the same setup to eliminate the need for an auxiliary air compressor after startup
Extremely impressive and love the idea of letting people get involved and refining it!!! Great work!
Amazing work dude! WOW!
yes totally dyno it :D
That is so cool. Well done sir.
"It's all free" We're either about to see a lot of free valve miatas... or a lot less miatas lol This is amazing. Subbed for sure.
Have you considered using the a/c compressor as an air pump? With a pressure switch in the tank wired to the clutch you can have it come on and off as the pressure is needed.
