They already make a 2 rotor version of this so that would only mean 2 engines needed

[@NorwayVFX]

If only it was that simple. You can easily stack the housings and "irons", but the shaft will be almost impossible to make without some serious equippment and knowledge. When you go beyond two rotors the shaft needs to be made in several parts that go together during assembly. You would also need some sort og bearing support in the middle for the shaft. JohnnyQ90 managed to make a 2 rotor shaft himself after several tries and he has years and years of experience with machining small parts. A 3 or 4 rotor shaft would probably be 5 times for dufficult than the 2 rotor shaft he made.

[@jasongaunt]

[@GeorgeChar95]

I would love a 787B RC with a real rotary engine in it!!

[@williamkillingsworth2619]

Flooded at start up, melting plugs and exhaust fell off. Yes that definitely is a rotary. Surely not making any compression at low rpm. Lack of side seals and housing to rotor clearance allowing blow by. Btw that is pretty cool!

[@WarpedYT]

Blow by like a mo-fo

[@Jawo_o]

@@WarpedYT are you going to put turbo chargers tho?

[@Joebobinator]

Most rotaries don't make good cold compression, the internal operating temps are high especially around the exhaust ports so they have to design them so that the clearances are right at operating temp. Piston engines get around this with ring gap, Mazda uses spring loaded corner seals to give the apex seals space to expand. Also like you said, no side seals but it might just not be feasible to make side seals for something this small. Even in a 13b the side seals are thin and fragile, they would probably look like strands of hair for this thing lol. Looks like there's thin metal plates that go between the rotor and 'irons' that may be an attempt to create some sort of consumable side seal that covers the entire side of the rotor face instead of being recessed into the rotor itself. Probably good enough for something like this, seemed like it was ripping pretty good once it got warmed up. Probably didn't help that he disassembled it, dropped some pieces, then put it back together in a dirty environment. Even a tiny bit of grit would clear itself out but put scratches in all the sealing surfaces on its way through...

[@WarpedYT]

@@Joebobinator your dead on about everything except the disassembly, see what I didn't show was I tried 30 times to start this engine, it wouldn't start had absolutely no compression, then I proceeded to disassemble the engine and I found a completely seized Apex seal. None of the parts were dropped. But yeah I'm going to upload that as a separate video on my other channel and share it here.

[@williamkillingsworth2619]

In this micro application I wonder if a one piece circular side seal could work to help mitigate the blow by and add compression, similar in position to the oil seals on a 13b. It could sit just inside the bottom edge of the apex seal slot. Trevor, Mazda used 2 and 3 piece apex seals in the majority of their production engines which allowed the seal to cope with thermal expansion and self clearanced between the irons/side plates. The corner seals where there because the side and apex seal had too much dissimilar movement and allowed tighter clearance. The important tolerances on 2 and 3 piece seal engines arethe apex slot to apex seal, the side seal to corner seal, and the corner seal to corner seal slot. I used to build 13bs and some what reliably made around 450rwhp with them on pump gas. Now with a 1 piece seal like was used in 12A and ceramics in racing applications you had to clearance the apex seal to the rotor housing width. But 2a d 3 piece seals self clearanced.

[@Joebobinator]

@@subifudriftkings Agreed, as the owner of a few rotaries and currently an Rx8 at ~250k miles with 3 engine rebuilds all of this is normal. The internal clearances don't tighten up until it's warm so they hate cold starts even with modern computerized fuel injection. This looks like a pretty rudimentary carburetor setup, of course it's gonna hate starting. Also I was cringing the whole time he ripped it apart in a filthy environment, dirty hands, dropping parts, not bolting things back together right, and expecting it to run perfectly? The exhaust fell off ffs, that's not "rotaries suck lolol" that's you not bolting shit together. Also super bad for the exhaust ports which are already the weak point for most rotaries, the heat buildup is bad enough even with good header flow. Also, please center that flywheel and put either a heavier one or some load on the engine. This is like taking an LS, leaving the balancer and flywheel off, removing the rpm limiter from the tune, then starting it with your foot on the floor and expecting it to go well. If you want to spin anything to 1000 rpm let alone 30,000 rpm you had better make sure it's balanced. This little engine is cool but man this guy is handling it poorly. Even if it wasn't a rotary he should take a little better care of it especially for a demonstration. Also their technical manual says it's only supposed to run to 16,500 rpm. Go take a Honda motor, rip it apart in a sandbox, put it back together just enough to run, then spin it to 15,000 rpm and see what happens...

Also note the rotary is one of the easier engines to do that too, I chatted with a guy who built a 12 rotor engine from 6x RX-7 engines (I think it had 12 turbochargers in total), and then he sold it to fund his next new project build and toy. Its probably just about as expensive to turbocharge them, just the exhaust manifold was like $3k a year ago (its since gone down a lot, and yeah you could weld one yourself but I'm referring to just bolt together options).

Would be interesting to connect that motor to the engine and see how much power you can generate from the engine.

[@garygaarderjr9733]

The starter motor would slow it down unless you had a faster brushless motor, which that one wasn’t.

[@Xenon777_]

@@garygaarderjr9733 yeah it would slow down but it would be interesting how many watts could be drawn until it stalls

rotary engines make a nice small engine for EV range extenders

Waiting for your "That sounds like a Rotary" t-shirts/merch 😂 Love it man, thank for the vid!

[@FarmerFpv]

I would have taken it apart after running it. I feel it was compromised from being taken apart as the head surface torque, gaskets, flywheel position, Apex seals and springs are very sensitive. Would be nice to see one that hasn't been tampered with run.

[@WarpedYT]

One thing everybody on KZbin is teaching me I can't leave any Stones unturned. So I did run it before taking it apart, or at least I tried, the only reason I took it apart is because it didn't have any compression and a Apex seal was stuck. Guarantee you I can make this engine run better than it comes from the factory. I have built hundreds of rotary engines including peripheral port and Bridgeport, this engine is a piece of cake compared to a real rotary that has corner seal side seals two-piece Apex seals with springs, you have no idea unless you've actually built a real rotary, the seals are a pain in the butt. This engine piece of cake there's really nothing you can mess up unless you lose some parts.

[@GFTPSMP]

@@WarpedYT , Matt, how tight was your engine as received? Mine has zero chance of running as the stainless plates are sprung inward towards the rotor. This engine needs a major overhaul before it can seal properly and run as intended. What happened to your cooling fittings?

[@rcdieselrc]

@@GFTPSMP It needs a redesign

[@2000freefuel]

I'd love to see a multi rotar built using parts from that tiny engine.

[@MrJdsenior]

Yeah, but you need one major part that is not there. It would be easier to just couple two of them.

[@2000freefuel]

@@MrJdsenior Sure, now let's build a 6-rotor for a go-kart!

[@vinniepazzz]

You flooded it! Just as common as low compression

Just FYI, Berkeley has Rotary engines that work that can only be seen in a microscope.

[@jakegarrett8109]

This engine's got 11 mHP! customer: "m HP?" Dealer: Micro Horsepower! As seen on electron microscope.

It's cool but 500 dollars?! OMG😂

[@RustyInventions-wz6ir]

Just found your channel and subscribed. Nice engine

[@donaldduck4867]

I think you screwed it up by taking it apart. Gaskets need to be replaced with new ones when you disassemble an engine.

[@mrbmp09]

If the gaskets aren't torn up they are fine.

[@Justintime2-j1f]

No they dont need to be replaced, as long as there is not toomuch dammageits perfectly fine.

[@TheIceGryphon]

I always wonder how much actual electricity you can make from tiny motors.

[@TheExplosiveGuy]

There are some pretty spicy mini generators out there, using gas turbine engines, some of them can make upwards of 10,000 watts in a unit the size of an 18 pack of beer. Spendy AF though.

[@mikesalive]

Motors like this do not make electricity, they spin wheels. However, you could attach a small generator to the output shaft and drive it. He said this motor generates 0.7 of a horsepower. 1hp = 754 watts, so that's around 520 watts output... shove that into a small generator at whatever efficiency and you'd end up with something lower than 520 watts. So theoretically you could generate enough to run a few light bulbs or a diy electric drill. That being said, it would be more efficient to attach a drill bit directly to the output shaft of the motor and do some damage against a wall like that. You could make a great little chainsaw :P

[@TheExplosiveGuy]

@@mikesalive three phase brushless motors are excellent generators, what are you talking about? They require extra components to make use of it to convert it into usable power but they certainly do work. That's how regenerative braking works in electric cars, the motor gets turned by the wheels which generates power to charge the batteries.

[@mikesalive]

@@TheExplosiveGuy Sorry, I was replying to the op. Your comment didn't show up for me until now, and yes, you are correct.

[@dogdooish]

Your "Other" Wankel looked just like one that I own , made by OS in Japan! Seems you need to tune it as well!

If I remember correct they made a “radial” engine where the cylinders heads move and not the crank. Not the same as what you are saying but still pretty cool.
