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.
With best regards

He's fully built a 2 stroke 50cc engine, and is currently trying to tune it to run on Nitro AND supercharged, to make the most powerful 2str 50cc motor for fitting into a bike for top speed runs. Alex also has a quirky sense of humour. it is a GREAT channel to watch if you love all of this home engineering stuff. Another channel is 'AutoBeta2T', where he is copying a famous motorcycle magazine's challenge of tuning a 90's Kawasaki AR50 to do 100 MPH !! (ALL home tuning and building!)

@kyleorr7039 2 года назад

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.

Very similar to a valve train I designed for a science fair in 1979. Poor high school kid so my model was built of wax, and plastic. So cool to see it probably would have worked. Mine used ball valves on a common shaft that wasn't hollow, and turned at 1/4th crankshaft speed so that the valves opened in the opposite direction each time. I worried about compression, and oil seep, and never could figure out how to seal them effectively. Thanks for doing this. I still think about building a working example to occupy my mind sometimes when I can't sleep. Life has a way of consuming all available time.

@Tommy_Mac 2 года назад

Fantastic! I'd suggest modifying the rotary valve so that it can ride on plain bearings on both ends. Oil seals could be used to control the oil and seal the oil supply from the combustion chamber. The rotary valve could ride on the plain bearings on a hydrodynamically lubricated surface. This would also seal off the combustion gases, preventing a loss of efficiency and lubricant dilution. Also, buy yourself a drill-driven cylinder hone. This would give you much better results, is safer, quicker and easier than resurfacing the cylinder wall on a lathe.

This intake and exhaust has potential to handle as many revs as the rest of an engine can stand. This whole engine was built experimentally and even the valve system will need further refinement, this is just a proof of concept, if the rest can be built to rev to whatever, this is no longer the section that can be the point of failure or that just can't exceed a certain amount, that valve system could rev almost infinitely high.

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.

@samhendrix378 2 года назад

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 Год назад

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

@angusmurray3767 Год назад

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.

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.

@@jeffersongaragecustoms6431 there might be a easy way. he could "dig in" a small oil tank dedicated to the valve drum. and on the other side of it (where he now have the oiling sistem) something like a razor to eliminate the oil and thow it on the chain. its a simple and allso veriffied working solution. its allready incorporated into the cilinder function.

@@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 2 года назад

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.

@waynegilchrist1596 Год назад

Congratulations! Sounds great. I'm so glad you didn't give up and I'm glad for you as well. A couple suggestions; (1) you should do a compression test (2) an exhaust will redirect that "in your face" smoke and will probably increase compression just a little. Thanks for sharing.

@Azmodon 6 месяцев назад

there's no point in doing a compression test lol the oil pump is directly exposed to the combustion chamber, and the valve tube has to be loose enough to leak when it's cold, so that when it's hot it doesn't seize. It's a catch 22, if it lives at low RPM, there's a healthy mix of oil, not only cooling the shaft but lowering the exhaust temperatures, everything besides that is great... if it lives at high RPM where the chamber pressure will limit the flow of oil out of the weep holes so it's not acting like a diesel, it'll clear up and be able to run mostly on the petrol... but then the valve tube has no lube, valve temperature spikes, things get bent. If the oil delivery was blocked off and forced to oil the valves, regardless of rpm dosing, you've got shock loading on the oil pumps gears (install check valve to fix that), then a metering valve to at least limit how much oil you're burning (at which point means swapping to a controlled oil metering pump... like rotary engines use, for the same purpose)

Fantastic job , being a mechanic for 50+ years the Rotary valve is a great design, but the oil system you have to the rotary valve shaft will cause excessive smoking , oil consumption , I think you need to redesign the oil system so the oil is not pulled into the intake cycle and causing your smoke and oil problem, if you can solve that problem you have a engine that’s better designed then a valve and cam design! Your work is amazing!

@jeffreyyoung4104 10 месяцев назад

I am so glad you took the comments to heart and proceeded to succeed! Try a little less oil in the fuel, as the engine is oil bath, unless there is no spray or slash system, otherwise I would be tempted to forgo any oil! The other reason for the smoke could be oil from the rotary valve system!

@@JusstyteN I accept your point and I raise you this one: This prototype does not yet have an effective lubrication system for the cylinder walls, or any sort of PCV system. Oil was added to the gasoline to lubricate the cylinder in the meantime. This is the reason for the smoke, and would not be a problem in a normal 4-stroke engine. Would very likely be added later in the development cycle, an easy oversight for now.

@MrAlton1991 7 месяцев назад

If you used mixed gas to lubricate the rotary valve isolated from the oil system or a few ring groves on the valve shaft to keep the oil from entering the combustion chamber there would be less smoke. I really enjoyed the videos and think it could be a great idea and less moving parts than push valves. A 2 stroke design would be cool to see as well!

@miketee2444 2 года назад

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.

@t_c5266 2 года назад

A cold air intake? I don't think you understand what that does. A CAI is for cars where the vehicles intake is inside the engine bay, and typically sucks in warm engine air through a restrictive tube that's all trapped under the hood. A carburator like he has is already better and the only improvement would be a nice filter on it as it's already not sucking in hot air. Adding tubing like a CAI will increase air friction loss and reduce his performance while not sucking in any colder air.
