Same, I was wondering what rotating part he was reading off of with the meter.

It just seemed strange that it idles ad 5-6,000RPM but I guess it does!

[@timz1908]

You would measure rpms at eccentric shaft, the output of the engine. You would not measure at the rotor, an internal engine component. We dont care how the engine does it we just need to measure the output. But yes the actual rotor itself will always be rotating much slower than the e shaft, by 1/3, one of the designs strengths.

Hard to tell, but if I could pour 1oz in that wankle, that'd be 30cc or .03x80ft/lb or 2.4 ft/lb peak I'd guess around 12k?, perhaps 2ft/lb at 16k? So maybe about 6hp? Just my ball park guess with no more than looking at the video with the most basic data.

[@Cerberus984]

That engine appears to be a O.S. Engines 49-PI (0.3CU / 4.91CC) based upon size in relation to hands and it's RPM achieved. The 49-PI is reported as outputting 934 watts / 1.24 HP at 17,000 rpm and torque is about 0.37 ft/lbs. So @ 29K rpm it would be outputting ~1500 watts / ~2 HP. All the other engines I've seen are 20CC or larger have thinner fins and lower rpms.

[@JimmysTractor]

Cerberus984 I thought it was 6 times that-whoops. I estimated 2ft/lbs at peak hp, you say .37ft/lb. So, you think peak torque is at peak rpm? Now that I have displacement, I'd figure 1/6 my up guess- 1hp at ~16krpm

[@Cerberus984]

@Jimmy's Tractor I simply used a 2 input toggle calculator that asks for rpm + torque or rpm + hp then solves for other. Then sourced my data from Barnard Microsystems which displays a vast variety of RC engines. The fins are equally thick on the OS engine and has same amount of end plate bolts. Although, the first two fins right of the exhaust port differ from the video I saw to the picture from my data source there were two different generations of that motor. The next step up (different brand) is a 20cc Nitto NR-20EP is significantly larger from the videos I've seen people holding it in their hand or on a bench top.

That seems about right on the RPMs since there's so little rotational mass. I've done alot of thinking on the designs used in most rotary engines. Particularly the rotor itself. The biggest problem at the rotary engine faces to prevent it from becoming the best engine ever in my opinion is its efficiency. A lot of its energy is lost before it can never be converted into mechanical energy. I think that can be fixed by rounding off the lobes on the rotor. Making each combustion chamber round instead of square. This would allow one solid ring per combustion chamber rather than the ones that are piece together at the corners and allow some of the energy to escape. The rotary engine an amazing engine just because of its simplicity. So making it even more simple is the best route in my opinion

[@JustKyzuuh]

Rotary engines are thermally innefficient by design, what you're thinking won't change that.

[@burritomaker69]

Whether it be a traditional otto cycle style of engine or this Wankel its not possible to achieve greater efficiency by any of the methods you mentioned. Both of these engines face similar problems with irreversible processes therefore it could be no better than the Otto cycle. For example by rounding off the lobes you'd decrease the combustion cycles efficiency to do work on the rotor. There is a reason the wankel has used basically the same lobe shape since its inception. Lets say that you did find an optimized shape to achieve what you're saying the main problem is still not optimized by doing that. If you'd want to make an ultra efficient Wankel you'd head more towards the material science aspect of things and need to probably look toward the use of materials like ceramic that way you could run hotter fuel, that would do what you said in your original comment. Now of course using ceramic brings in a host of other issues as well and that's the problem.

[@Rahziel420]

uncleweirdbeard The lobes and the "wobble" are how it achieves compression. That would be like taking the crank out of a LS, and replacing it with a straight rod. Sure there is still a combustion chamber, but with no compression.

[@BIGGlep]

They are actually fairly efficient when run at a single speed with non overlapping ports, but you'll never get good power that way.

[@JJ_ExMachina]

Wankel makes for excellent airplane engine... Where you pretty much set a certain RPM and stay there for extended period of time. By design the Wankel makes for a pretty terrible "car" engine. SO while it does work in ground vehicle applications, the rotary engine is best suited for high RPM airplane engines that only require a narrow rev range.

Seriously though, is there something with the side port engine that limits you guys? I would take my Turbo II to 9500rpm all day.

[@nickmendez3707]

JViello the rx8 13b renesis reliably revs to 10800 stock so you're nothing special.

[@JViello]

That's what I figured Unco, thanks for the reply. Sooooo, maybe he meant 19,000 rpm? LOL

[@NateRist]

The limiting factor in production rotary engines is the rotating assembly balance. It might not be an issue here as there is only 1 rotor whereas Mazda rotary engine come in 2 and 3 rotor configurations and 4 rotor race applications. If the rotating assembly is too far out of balance spec it will wobble and cause catastrophic failure. Basically the better the rotating assembly is balanced, the longer the engine will last at higher RPM.

[@drjmansplace5174]

Math doesn't lie. Great work. Especially Proofing your results.

Anyone know the music used from 6:02-6:23? I tried a few music recognition sites with no hits. The music along with that transition into the slow motion footage of the fuel being injected into the rotor housing and the engine screaming to 27k RPM was goosebump inducing. Good freaking job.

You can try to use a sound analyzer too, for speed measuring

[@-danR]

I seem to recall he did that once, using Audacity.

[@ChrisBLong]

That's what I was thinking. 483 revs per second with 3(?) exhaust pulse per revolution should give a note at about 1449Hz. I'm not any kind of musician but that seems to match the note on the video quite well.

[@G33RTJEH]

Actualy, it's only 483 exhaust pulses,. The rotor runs at a 1 to 3 ratio...

Great job on the math. Enjoyed the show. Thank you.

[@LucyanoLuci]

From what I know when the rotor does one rotation, the shaft does 3 rotations, so if you got 9.666 rotations on the rotor itself, and 29000 rotations at the point of measurement. Well, that's the math explained my rotary mechanics, not me. All the best! Great vids!

[@sterlingroberts6240]

LucyanoLuci but the number that would appear on the dash of a vehicle would still be 29,000, yes?

[@LucyanoLuci]

@@sterlingroberts6240 Theoretically, yes,but in normal rotary engine you will never get this very high rpm.

[@32inquisidor]

[@avsti]

Wait when you counted the frames wasn't that 6 frames to rotate 120°? So was the real RPM closer to 9600?

Actually, in rotary engines, the output shaft rotates 3 times faster than the rotor. What he measured was output RPM.

Usar lâmpada com luz estroboscópica vai facilitar ainda mais as análises. Sugeriria ainda adiantar o ponto de ignição, que talvez devesse ser móvel, para atuar em rotações ainda maiores. Além disso imagine aproveitar a combustão numa turbina de jato reator, e injeção de água, onde o Hidrogênio aumentará também o torque.
