@@silvestree1 There's only one combustion chamber though as each cylinder has two pistons which each combustion event pushes them outwards. Being the opposite of a boxer commonly used in Subaru or Porsche engine.
Converted to an opposed piston two stroke. Simply amazing! There are guys out here with FAR better tools and no mean level of skill who could never do a project like this. One of the things I enjoy about channels like yours is the can-do attitude. You guys just make it happen! Well done!
The presentation of builds in this channel reminds me of the Primitive Technology channel where the creator doesn't talk at all. But that channel uses the subtitles to provide some background on what is happening in a scene. I think that idea would work well for this channel too. The builds are really intricate and I'd like to know a bit more about what is happening through the build.
The problem would be the lower chamber. While you could separate one piston from the next, how would you separate 2 pistons on opposite banks? But there's ways to solve that, like instead of using the lower part of the cylinder to create pressure, use a positive displacement supercharger
Your expertise in building something out of just a few bits and pieces is amazing and your sparts department is impressive carn't wait to see this impressive piece of workmanship running. Absolutely Amazing.....

Если ты дуб дубом, ты хоть сто чужих видосиков посмотри, толку от тебя не будет.

Maybe make an oil tube to the other crankcase. Great job though . Chrysler made a TS3, and there was the junkers back in World War II. Recently, Cummins joined Achates and made a 2200 hp diesel two-stroke. Not available to the public though . Military applications only . Keep up the good work - there’s also a variation where you can connect with a third opposing engine connected to the one you have.
Wow 2 Ang utak ng gumawa nito. ❤ Galing. Ang tanung magandaba Ang menor nito. Bilib nako kung makikitako na matining Ang andar at maganda Ang minur nito. Pero Ang galing..wow🎉
I'm not sure it will run, the exhaust and intake ports are set up for a closed cylinder (normal 2-stroke set up), the opposed piston engines that I've seen that run on gasoline have the ports for intake charge and exhaust release at opposite ends of the cylinder. It will be interesting to see an attempt at starting this engine, but excellent machining, kudos.
He did make the exhaust ports at the bottom of each individual cylinder, and the crank case pressure/ vacuum is connected to eachother in the spot where the timing chain used to go. Just that they use the same reed valve and carburetor
I like the concept of using two flat head engines offset the valves and with a spacer create a 4 stroke OPOC engine. But the work done here shows incredible skill.
I'm saving this to watch in my workshop tomorrow while I work on my 5th gen VFR that has gears instead of a cam belt/chain, looking at your thumbnail I think thats relevant.......👍👌👍
Wow that's amazing! I didn't even know you could make an opposing engine like that to fire two cylinders off of one spark plug That's crazy! I mean that's how it looked to me anyhow unless I missed something.
When he was cutting the intake runners in the cylinder, I was thinking 4 cycle. I was like.....he just screwed up! LOL. I should have known better. As a machinist of 35 years I verify this guy is the real deal!
Продувку нужно было делать только в одном целиндре без выхлопа а выхлоп в другом без продувки , тогда движок будет работать гораздо эффективнее и проэкт интересней.
Excellent build, question, did you use 2 stroke pistons as they have a dimple in the groves to stop the split of the compression rings going across the ports
FANTASTIC EFFORT! But, I can see a few problems... -- (1) WHERE IS THE SUPERCHARGER? In normal 4-stroke engines this is used to make more power, but for an O-P engine, no supercharger means it wouldn't run at all! In O-P engines the exhaust ports are uncovered first which allows most of the exhaust gases to escape, but when the intake port is uncovered the cylinders are still at atmospheric pressure or higher. If the intake is not at higher than atmospheric pressure nothing will go into the cylinders as there is no intake stroke draw it in. The intake has to be at higher pressure than the exhaust to push it out and replace it with the intake charge. -- (2) Related to (1) is the issue of throttling. How do you plan on throttling your engine given the constant positive pressure requirement? Most O-P engines -- from the Jumo 204 to the FM 38 D8 1/2 to the recent Archates and Cummins ACES -- are DIESEL engines, so they don't have this problem. Diesels run at Wide Open Throttle all the time, they simply meter more or less fuel and run lean on lower power settings. -- Another nuance... O-P engines typically have the output crank shaft running about 10~15 degrees ahead of the follower crank. That is the crank connected to the transmission needs to run ahead of the follower crank and it actually carries 80% or more of the torque. In fact the follower can be driven by chain if you want -- it doesn't carry that much load.
You need to add a carburetor to the other side too (at least a small amount off oil to lubricate the crank and piston) , 2 stroke need's to have the bearings lubricated by the fuel/oil. the oil from one won't reach the other crank and will ruin the half that's not being lubricated..
NEXT UP? How about a pair of vertical-shaft Briggs-style flatheads, joined with deck plates. The plates have to be bolted on with countersunk allen head bolts and pinned, so the spark plug hole(s) threads stay aligned. (If the plug(s) are centered in the parting line.) Then the plates are bolted together around the periphery, that's made bigger than the barrels. The valves of one engine could be directly over the bore of the other engine. So it becomes an opposed piston overhead valve 4-stroke. Could have high-compression and excellent breathing, plus some of the advantage of opposed-piston.
How does the top piston bearing get oil? I’m sure it would burn out over time unless you plan on running an external oil pump that’s maybe electric driven?
1. Opposed-piston engines only make sense if the full cubic power is used. 2. The outlet must be opposite each other and must open and close earlier. 3. Two-stroke engines as opposed-piston engines have the ignition on each piston center. 4. Two-strokes require large pistons over small pistons as a pre-compression space. 5. From 4. it follows: Only the piston + cylinder combination effective without 2-stroke disadvantages. 6. Very high efficiency due to better cylinder filling and combustion.
Opossed piston adalah mesin terkuat.. Kau telah berhasil membuatnya... Tapi... masih ada kekurangan... Kau membuat piston bawah sebagai hisap... piston atas sebagai buang.. Seharusnya.. tetap seperti 2stroke biasa.. keduanya sama2 punya lubang buang n hisap. Kalau tidak... maka.. si piston buang yang akan cepat hancur, karena dia uang dapat bagian panas.. n piston hisap selalu dapat bagian yang dinginnya.. Cobalah sempurnakan lagi mesin opossed mu...👍🖒
Untuk mengerjakan sesuatu apapun kalau ada bahan sama alatnya siap, maka pekerjaan itu akan sangat mudah, di tambah dengan ke ahlian dan pikiran orang nya
good fun but a bad engine 1. plain little end bearings will seize. 2. there's no scavenge loop so exhaust and inlet gasses will mix. 3. the piston rings are not pegged so the ring ends will get stuck in the ports. 4. the volume of the camchain tunnel will reduce crankcase pressure. 5. the steel housing and six gearbox cog crankshaft coupling arrangement is far too heavy and will add significant drag. 6. there's not enough oil in the crankshaft coupling housing. 7. the crankseal housing plate will prevent the gear selector arm's movement so the gearbox won't work. And I think the compression ratio will be too low. This engine will be under powered, overweight, inefficient won't change gear and will fail within 2 minutes of starting.
Me llamo la atencion quiero creer que tenia la relacion de comprecion justa y los grados de apertura de los transfer es mas uso pistones de 4 tiempos hubiese sido lindo verlo en marcha pero bueno
Can't wait to see this running big. That's some serious compression.
gonna need some high octane fuel for that

@@silvestree1 There's only one combustion chamber though as each cylinder has two pistons which each combustion event pushes them outwards. Being the opposite of a boxer commonly used in Subaru or Porsche engine.
@Satoru yes but there's a spacer for the spark plug which would be the combustion chamber
@@silvestree1 It's the same combustion chamber so it will be equal unless one has a shorter throw connecting rod.

It isnt better a chain system for coupling the 2 cylinders? And why the second flywheel, it wasnt enough one ?
