I built a brand-new Rotary Valve Engine, and it works!

Many of you have seen the process of making this rotary valve engine with different intake and exhaust system and how I tried to start it.
If not, then let's watch the previous video first:
• I built a brand-new en...
After so many attempts to start this engine, I was ready to give up, but your incredible optimism and support inspired me to try again.
Thank you so much for your support, after reading all the comments I had no right to just give up.
Let's try to run it together.
I've highlighted some of your tips. So let's follow these tips one by one and see if the engine will work.
For those who don't know what the video is about.
I had an idea for a long time to create an engine without valves and springs.
Fuel and air enter the cylinder through a rotating shaft, which in turn is connected by a chain.
At the right moment, a channel for injecting the fuel mixture opens, and after detonation, the fuel is released through another channel.
As it turned out, there were a lot of variations of such engines, and many of them had already been used in the past.
As you have already noticed, I read almost all of your messages and am happy to share my ideas with you, and as far as possible, I listen to your opinion.
Share your opinion on this and leave comments.

[@kyleorr7039]

I’m 52 years old. In 1982-1983, I was drawing a mini helicopter in school during science class. I had no idea that a Wankle, rotary motor existed but I drew up a motor without typical pistons and valves because I couldn’t understand why there was so many parts, including moving parts. One of the very first ideas I had was to get rid of the valve along with the push rods rockers and cam. I wondered why there wasn’t a cylindrical shaft that had slots in it to open up at the correct time for fuel to enter and exhaust to escape? Later, I then thought about the piston itself. Why up and down, why not a large cylinder shaped shaft with a slot cut out of its side for a combustion chamber as it rotated. So, to make a long story short, you just woke up a dream that I had always wondered about for more 40 years and now it’s a reality. You are an amazingly talented guy. Great Job my man.

[@SlowSTEN]

I'm assuming what you made was a mixture of motor oil and gasoline, id recommend using 2-stroke oil instead of motor oil, see if that improves the smoke any. Also, this thing is AWESOME.

[@jeffersongaragecustoms6431]

He did mix a little oil with the fuel, but the smoke is from burning oil out of the crank case. I'm not sure how to correct it, but the oil is getting to combustion chamber around the valve drum and it is consuming its own life blood. Super cool to see a radical concept physically work. With a bit of refinement might be able to solve the oil consumption issue. My left field idea has been to run "conventional" valves off of solenoids.... near infinitely adjustable valve timing. And no parasitic loss.

[@SlowSTEN]

[@metalord53]

@@jeffersongaragecustoms6431 Maybe something more simple would work like a reclaim cavity or something along those lines. It is difficult to seal rotating without a sealed bearing or something similar. But maybe if there was a way to have it run off before getting to the valve tube openings?

[@seanwayment9361]

Crazy idea...what if there were two valve tubes? One exhaust and one intake. Using bearings that maintain center and are the only part of the system in the head that are lubricated. Could help with compression if sealed well. Additionally it would give more timing options but require a new cylinder. Also gear ratios would come into play...math.

[@sticker89]

Some suggestions to improve engine performance: 1.Use 2t lubricating oil 2.Add mechanical seal on both sides suction control shaft to reduce oil burning 3.add two ball bearings on both sides suction control shaft Use a thicker intake control shaft and increase the intake opening,reduce inhalation resistance,it will be better!

If you can figure a way to seal the rotary valve with oil seals so the cylinder would not receive so much oil and less compression loss the engine would run fantastic, Great job, thanks for the videos.

[@rrmcbride555]

he needs to make it 2 cycle and put the valves in the ports. That way he can turbocharge a 2 stroke.

[@angusmurray3767]

The lack of seals for the rotary valve is the engine's biggest design problem. It causes loss of compression and sucks in oil on the inlet stroke. A partial fix for this is to have separately fed plain bearings at each end of the shaft with viton o ring seals at the outer ends of both ports to prevent oil being drawn in on the inlet stroke. There will still be some compression loss around the annular space between the shaft and housing as high pressure gas leaks to the inlet side but at least the compression loss will be reduced and the engine won't burn oil. Because the shaft is a reasonably small diameter, Viton should be able to cope with the rubbing speed but it is essential to use Viton to cope with the high temperature generated. The groove depth needs to be carefully controlled to get sealing without undue compression of the rubber which would cause it to burn. The system isn't new as this design has been used on motorcycle engines where the rotary valve has been driven by bevel gears.

[@Kismetix]

@@angusmurray3767 Agree with everything you wrote. I think there was another example of a rotary valved engine, which was used in the Hawker Typhoon around the time of WWII....that one however was a rotary sleeve type that also formed the cylinder wall, if I remember correctly.

[@davidelliott5843]

Electro-pneumatic poppet valves can vary the timing. No camshaft needed just a trigger wheel to open and close the valves. Different wheel = different timing. Mount the valves vertical with sacrificial rockers and you can have a few timing mistakes with no harm done. Check out how Fiat built their twin cam 16 valve 1.3 diesel. It’s an efficient and very clever design.

I watched every second of your original build and remember thinking , when you painted everything before you had even tested it, that you are an eternal optimist. I was disappointed when it did not run. This video makes me very happy for you. Just a quick question. As they engine is self oiling, why did you add oil to your fuel? It certainly turned it into a smoke monster. Or do you need oil seals on your intake/exhaust shaft. Just a thought.

[@Six_Gorillion]

Not an expert but two stroke engines do benefit from oil in gas mixture to keep it wunning smooth. I think chainsaws and mowers do this and the only bad thing is the smoke.

[@TheWolverine-rm2kr]

@@Six_Gorillion That would be a 2 stroke this is supposed to be a 4 stroke

[@Roberto-oi7lm]

I would imagine oil in the fuel would be beneficial in this prototype for two reasons. First, keeping the rotary valve lubricated is very important and it would take quite a bit of developmental work on various materials, seals, and oiling schemes to arrive at the right combination for reliability and longevity. Adding oil to the fuel is a simple precaution to quickly and easily solve a potential valve lubrication problem. In addition, cylinder wall lubrication of a 4 stroke engine isn't straight forward either. Most small engines like this rely on a "splash" system where the crankshaft literally splashes around in the oil sump and lubricates the cylinder walls when the piston is at the top of the stroke and then the oil ring wipes a film of lubrication up and down the cylinder wall. From the photos of the cylinder wall damage, it is clear that this engine is not being properly lubricated from crankcase oil alone, so introducing oil with the fuel makes sense. Remember, this is a proof of concept engine intended mostly to experiment with the rotary valve intake and exhaust idea. I would imagine that experimenting with valve timing, perhaps with a simple way to adjust the timing of the intake separately from the exhaust timing, would be the next step, maybe in conjunction with some ignition timing alterations. Refining the lubrication issues is of lesser importance.

[@daviousmaximus6446]

@@Six_Gorillion Firstly, it has a timing chain and an overhead rotary valve in place of traditional poppets. It is a 4 stroke. He may be adding the oil because he is worried about his cylinder wall I would reckon. The fuel doesn't go anywhere else. It's a beautiful thing that he can continue to work on to perfect oil control anyway.

Many would consider what I'm about to say a non issue but the fluid used when honing a cylinder is much more important than most think. In a performance engine where you want every possible equation covered I was taught to only use oil. Preferably the oil you run in the motor. Solvent based chemicals embed the silica or grit from sand paper or hone microscopically into the cylinder wall. I was always taught to only wash cylinder with soap and water. Doing this many times and on my two stroke motors only use the oil Mix with fuel as my cutting fluid and wash often in between. A dishwasher works great but yes solvents don't ruin an engine but eliminate any potential issues when possible. I like it. Keep testing and get those piston rings seated tight to stop all the blow by.

I'm reminded of "Sleeve valves" used in some old radial engines. It's no small feat to get it running, and honestly it seems powerful enough to take some load (someone said go-kart, and that seems pretty fitting). It has a VERY interesting meaty sound to it too.

[@MessyWorkshop]

Well done !! I am so happy to see this running !!

[@nickclover5124]

You should try and make a v-twin with only one valve shared between cylinders... so the rotary valve would be the intake for one cylinder while also being the exhaust for the other at times when there's overlap.

[@SBS_Auto]

Great idea.

[@haphazard1342]

1. Would the cycle timing on that geometry actually work? 2. Exhausting through the intake tract will make a mess of any carb you install on it. Could definitely have a single shaft with dedicated "valves" for intake and exhaust feed two cylinders in a V arrangement, though.

[@heckindoggodozoom3406]

I think you will have to modify the shape of the openings in the rotary valve. If you think about a conventionally four stroke engine the camshaft lobes are ”drop” shaped so the valves start to open slow and then accelerate for fast opening. Then they remains open and then for a fast closing action.

[@stevecummins7834]

Are you suggesting adding a twist to increase duration time open?

Автор скорее всего не читает иностранные для него коментарии, а так да, чем меньше площадь, тем меньше будет потерь, но мне кажется, имеет смысл делать стальную гильзу для золотника, с канавками под смазку, тем самым можно уменьшить зазоры, и уменьшить количество попадающего масла в камеру сгорания

I knew you could do it, I gave some comments but you had it going by the time I posted. You just need to address things like sealing the oil off from getting into the combustion Chamber. Also I would install bronze bushings in the block, where the rotor valve shaft Spins so it won,t wear the block out.That engine can be a living work of art if you keep perfecting it over time.

[@Hokkaider77]

I can well imagine this construction as a 2 or 4 cylinder boxer construction. Valve control is uncomplicated and easy. The only problem I see is the chain control. A bevel gear transmission would require less maintenance and be more robust. The honing of the cylinders is not optimal, less rotation but faster up and down movement would be better. How's the compression?

[@pauljs75]

Not the first of its type, as working models based on some variant of the concept have been made since the 1890's. You can find blueprints and patent drawings for them if searching for "rotary valve internal combustion" as a search phrase. However it's neat to see this one working given all the home-built aspects. Not exactly an easy feat for most people short of doing a direct copy of some known working engine. As for improvements? Seems the current version relies on oil around the valve drum to both lubricate and provide the seal around the valve drum. That's why it's one heck of an oil-burner. Might want to try some kind of graphite/bronze type material to seat in as a hard-pressed bushing around the intake and exhaust ports. (Similar material to electric motor brushes?) Maybe a ceramic felt as a crush/springy material with just enough give and resilience, and then the bushing would fit in the groove over that which keeps it located at the valve seats? Something soft enough to not wear out the valve drum and graphite to help it be self lubricating at the wiping contact surface. Thus something other than the oil film to provide a seal right at the point where oil would be leaking from the ports into the cylinder. Just a thought there.

Amazing work, I love the ingenuity you display in all your builds. Also I would love to make a ringtone of you singing hard work. So never give up always ask others when you are struggling, the answers are always out there you just need to know who and you could build a flying ufo just by asking a bunch of strangers to figure it out for you 😊

[@petesquickfixdiyshortautor1218]

UFO would be two spinning disks. The disks spin in opposite directions and have very small raised humps on the top side of each to create lift. The bottom disc has raised humps as well creating lift in the opposite direction. You think that downward lift would counter the upward lift but this is not the case because planes and even fighter jets can fly upside down. The upper disc spins faster than the lower to launch from the ground and the different speeds of each are used to control up and down. A gyro flywheel is used for left and right / forward and aft. A vacuum is created in front of the craft as air is pumped to the rear creating a high pressure on the rear part of the craft to propel it forward. This is a crude explanation of only a small portion of some of the needed systems. I'm just a stranger in need of more strangers with ideas to make it fly. Aloha

[@elonwhite6628]

@@petesquickfixdiyshortautor1218 the stability issue is caused by the rotation of the central propeller, the main problem was that it would rotate in one direction fine but trying to rotate in opposite directions to the propeller’s rotation would cause the aircraft to veer off centre and it would behave erratically, also the program was created, and then shut down before computers were even considered for use in aircraft’s

@@ashkebora7262 True. But this video series is about the valve train, not the crankcase.

This is probably the only reason why there was a lot of smoke, because of the new type of valve, I have a rich mixture in the fuel-air mixture and the fuel did not burn completely, but this problem is not insurmountable, the important thing was to make it a working project, congratulations, it is working now..

[@jamcat62]

I love that you got it running! I do have a question about the valve port(s) timing. I couldn't tell from the 1st vid. Is there any overlap of the intake/exhaust ports in the cylinder port? Most 4cycle engines have a slight overlap in the intake valve opening and the exhaust closing, to help the flow of gases. Just curious.

[@Skulljeep00]

The Atkinson cycle is the way to go for fuel efficiency over the Otto cycle. But for smoother running, understanding LSA (Lobe Separation Angle) on a camshaft, and the right amout of valve overlap from 10 to 20 degrees would boost engine RPM, power, and some MPG's/LPK's.
