It’s finally here! Thanks to everyone for all the support over the past few months, the response to everything is still mind-boggling. While this build isn’t done, This is the big milestone that I’m pushing for. I’ll continue to tinker with it in the future and I’m here for ongoing development, but please watch the ending of this video for more details.
Thank you so much!

  • 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!

  • 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.

  • 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.

    Leland HoltonLeland HoltonDag sedan
  • 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.

    Leland HoltonLeland HoltonDag sedan
  • 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!

  • 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.

  • 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.

  • 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?

  • 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.

  • 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
