[@ThomasBrandell]

@@Dappersworth the main reason that they aren’t more efficient (mpg-wise) is more due to the weight of the vehicle, where a lot of the mass comes in the form of safety equipment and comfort. Cars are designed to plastically deform in the case of an accident, which is a significant portion of the car’s weight. College clubs make vehicles that can go over 100mpg all the time, but they are not fast, comfortable, or safe to drive in normal roads. Not everything is a conspiracy.

[@motoxmuseum]

Using a rotary disk to act as the valves for a 4-stroke was my graduate project in 1980. It was based on a Honda XL250 engine. Obviously, a mechanical drive system as this level of electronics was not available at that time. The design used an elliptical drive gear to speed up and slow down the rotation of the valve so the valve was moving as slow as possible at the peak point of cylinder pressure. The rotary valve was sealed used a Dykes - ring or L-ring in the head against the valve. This used the cylinder pressure as a force against the ring to seal. The design was in my opinion very workable however the amount of funding needed to build a prototype meant it would only exist as a paper design. Of course, I was not the first person to conceptualize a rotary valve for a 4-stroke engine. There were several designs done in the pre-world War 2 era for aircraft engines in the UK. Those designs were based on a cone that rotated on the outside of the combustion chamber. There was enough data from these engines to show that a rotary valve design would have enormous advantages in fuel consumption and performance. The challenge was resolving the mechanical challenges to have a reliable engine. Ultimately, the use of a rotary disk creates disadvantages with the bore of the engine and the bore-to-bore spacing making it a questionable technology for multi-cylinder engines. It is fun to see someone 41 years later still working on the concept. Good luck.

[@ericchambers9023]

If you continue with the stepper motor design, you should look into using servo motors instead. Built in encoder position feedback, so you can have the microcontroller know where the valve actually is.

[@discontinuuity]

Rotary valves are nothing new, but I've never heard of anyone using stepper motors to move them. I can see this design having trouble with sealing, thermal expansion, and/or clogging up with combustion products. But it's a cool proof of concept. If you have trouble with sealing you could try Corliss valves. The pneumatic valves are still worth pursuing if you ask me. The pilot-operated valves located close to the head sound like a good idea. If differences in air temp are the problem you could put the air lines in a water jacket to keep everything consistent.

[@michaelappleman6172]

Rotary (and sleeve) valves have an ancient and illustrious history, especially in 2-strokes where they made the MZ's, and soon after the Japanese grand prix bikes unstoppable in the 1960's-70's, but in those engines they were upstream of the combustion chamber and didn't have to deal with sealing high compression in a 4 stroke or deal with exhaust temperature. If you can figure out how to solve those problems, you'll be an engineering superhero!

[@Acecool]

You could use the hall effect sensor with one main magnet for rpm, then use a secondary for timing... The rpm is so you can reliably predict where you expect the rotation will be without skipping teeth, then the secondary one will be so you can gauge where the wheel is using different size magnets so you get a different reading - this will let you explicitly define what each means. From there you can + or - in the code when it hits those spots... so the main rpm will guide the motors so it should be close, then the others are for exact - this is where you should be. You can simplify it and use those variable magnets for rpm knowing how many there should be. So limit the number to how many explicit instances you want - you can use piston location for full top, full bottom, or 4, or the number of individual valve movements, full open, start open / end open, etc... you won't need that many.

Kawasaki used a similar design on their 2 cycle enduros back in the day called a rotary valve timed on the crankshaft super cool vid👍

Some more little projects/experiments to maybe try...: - Tank steering on a car? And how about a racing half-track? - How well would spark-controlled compression ignition work on a diesel engine? - Hydrogen Peroxide injection during combustion? (There's a pretty convincing research paper I read that tested this on a diesel engine; thermal efficiency went up, but emissions and temperature surprisingly went down.) - Virtual Jake Brake when doing Freevalve stuff(?) - What happens if you put an ICE and a Stirling engine on the same crankshaft; Could you use the ICE's exhaust manifold to power the Stirling engine? - For science, do you think you could use modern technology and knowledge to create a "next-generation" carburetor? (Yes, I know carburetors are obsolete, but I'm still curious.) - I'm trying to design a "variable inertia flywheel", which is supposed to expand at higher RPMs to simulate a smaller flywheel miraculously getting heavier. Do you think this would work? - What if you used vapor chambers and a peltier module to supercool your spark plugs? *Notice: I will not stop posting these different ideas on your videos until I see you try one of them.*

Have you considered using voice coils to drive the stock valves? Closer to the original free valve tech you started with I think. It would remove the 'squishy air' problem (not to mention voice coils for high speed/precision linear motion is just awesome).

I'm sure I'm late to the party, but my personal input on rotating disk valves: 2strokestuffing used them on his personally designed motors to great success...temporarily. Turns out, a disk valve under intake and exhaust load becomes a disk brake. He started the journey of switching to a rotating cylinder/drum valve and I wonder if that would work well in freevalve applications as well

[@williamhardes8081]

maybe a torrington bearing? could that help with the disc brake effect? separation of the surfaces would be controlled by how much you recess the bearing into the disc surface? not an engineer but just thought of it?

[@GleepGlop2]

Congrats on 100k!

[@WesleyKagan]

Thank you!

[@bullinahanky]

I feel like I remember a very similar design from a book I once read on early motorcycle engine technologies. I’ll have to do some digging and see if I’ve still got that book somewhere.

[@zoppp621]

Check out the BMW valvetronic system. In conjuction with VVT you have practically full control over cam phasing and lift.

[@moesizlac2596]

I wonder if it would help to have the rotating "valve" be machined to fill a channel or grove in the head to help with some of the sealing issues. In a later design you could put a bushing in it...

[@tycro]

Congrats on the 100k!

[@WesleyKagan]

Thank you!

[@PyroFactor101]

Add a nut and bolt running though the shaft of the valve to strengthen it a bit, you should also give pteg or asa a try before going through the trouble of making it out of aluminum

[@danielplumley2649]

Please keep working on this! I love the freevalve videos

[@Venturestarx]

This is similar to a valve system I invented about 17 years ago. Very cool!

[@brandonkikoak2889]

Equal length tubing and proper manifolds will go a long way. Take air "squishiness" out of the way by neutralizing it in this manner.

[@josephmills7186]

congrats on 100k! love the videos dude (been here since first porschekart vid i saw on reddit)

[@dolfandon7124]

What a cool idea! Here's hoping for success

[@schneider1492]

Have you ever considered a pneumatic bladder actuator. Air can get through a lot of tight holes that's why most pneumatic actuators are very temperature sensitive. a pneumatic piston has to keep pretty tight clearances so is it heats up it's going to seize. However a bladder is sealed and can use much looser tolerances on the item it's actuating. So as long as you're not getting everything hot enough to melt the rubber or silicone you should be fine.

[@Nebbia_affaraccimiei]

100k!!! congrats

[@WesleyKagan]

Thanks! It’s a huge milestone

[@kw2519]

Really interesting idea. I think you’re on to something with the knife valve. Perhaps with a mechanism similar to a weighted distributor, but reversed so the hole is partially obscured when at low rpm(small amount of “valve lift”) then have counter weights that remove the blade from obscuring the hole as rpm increases. The idea would be a variable sized inlet diameter.

[@StingrayOfficial]

100,000!!! Well deserved!!! Awesome stuff.

[@brandonhewitt2386]

I really like the concept. I wonder if a ball valve type would work? Love what you've done on the channel!

[@WesleyKagan]

Thanks! Hah, funny enough I actually thought about that, and for the fun of it I might do that. It’ll work great with air, but as soon as I approach 400F it’ll all come apart. So exhaust won’t work very well.

[@ferrariguy8278]

@@WesleyKagan Would using a thermal coating help? (piston tops, valve faces, exhaust ports) Plenty of options on that like from TehcLineCoatings or SwainTech.

[@jasgud]

Have you ever looked at 90s Bombardier Rotax 2 stroke. Snowmobiles, small planes, etc. They use a common rotorary valve for intake into a twin.

[@nateking6629]

Hi, I saw your channel from the comment you left on Drew Gooden's video and I'm glad I did. I watched your video on mechanical CPU's, and I'm looking forward to the continuation of it!

[@heidelbergaren5054]

For being a shooting from the hips engineering approach - those screws are pretty nicely lined up :-)

[@WesleyKagan]

All of that credit goes to my 3D printer haha.

[@heidelbergaren5054]

@@WesleyKagan Actually meant for the assembly on your blue sheet, but yes, that too !

[@benhowe2087]

No need for the ports to be round. You could make massive openings in the head and corresponding ports for huge flow numbers at high rpm. You could also use multiple intake ports and use slid valves to close off the large ports at low rpm for better port velocity.

[@THEONLYNIKOMATH]

I've probably checked your channel over 20 times since you last video waiting for more. Love the content and keep it up. My dad has a very similar jaguar that he needs to get running 😅.

Well you could try an updated version of the sleeve valve system used in the Willys-Knight engines where the entire cylinder liner rotates off a geared shaft from the crank
