Wankel engine and Quasiturbine

[ontheroad619]

every little joint, contact area, and seal would wear out so fast if it could theoretically run

[carlover]

ouch , friction between those joints ?

[SoldierCyfix]

the regular rotary has less moving parts = cost efficient

[stanglvr5point0]

more moving parts than a wankel, seems pretty pointless to me

[MrHurricaneFloyd]

Wankel puts out insane power for its size but is very inefficient and wears out too quickly.

quasiturbine only generate a lot waste of momentum energy

[logelamutp]

German!!

[RandomDudeStuff]

There are so many things that are wrong with the Quisiturbine. I mean, the concept if fine but there's so much friction, I have trouble seeing how it could work as a combustion engine. Then again it was never really meant to be one. It's a pretty powerful air turbine.

[DocWolph]

I like seeing these experimental engines, but What I would like to see are these engines being used in a car. Bolt one into a kit car and go prove it works.

[uttermeamumble]

@DocWolph they aren't experimental they've been used for years. 

[DocWolph]

@uttermeamumble I was talking about the Quasiturbine not the Wankel. But there are numerous other engine designs out there I'd like to see in practice as well.

[plexnoid]

All I know is that I want one of those rotary engine motorcycles!

[Austinflank]

The rotary engine is like a 2 stroke on steroids.

[Xenophene01]

This engine has always blown my mind. A triangle rotating in an oval wow

@GeneralWiggin

Rx7 beats Scirocco any day of the week. I drive an '79 SA RX7 and I worked as a mechanic at Volkswagen, trust me, from a mechanical point of view, the scirocco is a piece of sh**. + that it weighs a lot more then the RX7 doesn't help either. the only thing the scirocco has going for it, is the teeneetinyturbo, that helps it gain some momentum at start, however, after 3th gear, the turbo on that car is pretty much useless as it is too small to produce enough oompf at 80 - 90+ mph

[Olengher]

@dondebest yep Scirocco is a car mostly for South America and China.There VW is among top sellers, in fact it is top sellin brand in SA.Mazda is not first choice.Or second ... or ... you get it.VW shits on everythin Mazda ever produced at price/performance/quality.The cars are cheap and easy to mantain.You said you were mechanic.If you said another brand not Mazda with rotary, lol.

[dondebest]

@Olengher VW is pretty much Top seller in any country except North America and Asia. I however disagree on the price/performance/quality part. Quality is ok, although a lot of the low end models (Polo, Lupo, Fox) have issues with the ECU, they get a lot of recalls over here. The higher end models don't pose that problem however. About performance: No, they don't really have much power, except for the newer TSI and TFSI models, but over here, we had a lot of people coming back since their turbo

[Olengher]

@dondebest i comment on this car cos a friend had one.He never complained about the car just said it's not a good deal.He told me some numbers like 18l/100 and some tehnical revision cost and i belive the car is bullshitt and a VW its ten classes ahead.I mean cmon, there is not a single VW with 200 hp and 18l/100, that is poor, somethin is wrong.What does it do with the fuel?Not to mention the price.Btw, i found an article, the car is not Euro 5 compliant and was banned in Europe.Checkout

[dondebest]

@Olengher I believe I have to correct you on 2 things, not saying your friend is a liar, but if any car drives 18/100 you should start thinking about some engine or carb/FI issues. My rx7 drives 8/100. so that's pretty acceptable, and definetely impressive if you consider the car is already 32 years old. Also, the car is euro 5 compliant in every way. RX7's aren't banned anywhere in europe. To rebuild the engine, is roughly the same cost as a normal 4 stroke piston engine, the only big 'but' is

[dondebest]

Reageren op deze video...  That you have to find a engine builder that has knowledge about the rotary engines, luckily there are a few here in Holland, and Aussie and NZ are rotary-nuts, so enough help from those sides. My last note will be that a rotary has a far greater hp-potential, thanks to the limited number of moving parts. the flatter torque curve also helps in that, although certain tuning options (bridgeporting, peripheral porting) really numbs down the torque in the low end

[dondebest]

@Olengher (part 2) since their turbo seized because of lubrication failures. Mazda however, usually is the weird brand, people don't really know much about it, but they're gaining ground over here in Europe with their newer models. Other brands that use(d) wankel/rotary engines are: Citroen, Mercedes, Norton, Suzuki. Audi is currently experimenting with a wankel-hybrid in their new A1. Building quality however, far exceeds the VAG standards. You should read into it, it's interesting stuff:).

[xxxxcocotazoxxxx]

Nice but, will it blend?

[TheBlueguitar333]

what happens if the corner blade stops right on the intake valve? will the gas leak into two chambers and cause problems? ...im not a mechanic by the way....just interested in engines :p

[dondebest]

@TheBlueguitar333 With the Wankel (or rotary) engine, that is not an issue. Cause there are no valves;) However, if the apex seal stops on the intake port, it's fair to assume that you stopped the engine, so the little bit of fuel leaked into the engine, won't harm it in any way.

[Toad261183]

eh...bisogna vedere se funziona...ad ogni giro del rotore avvengono 4 combustioni (nel wankel 3) e questo sembra un evidente vantaggio!!la mia domanda è quanto potra reggere la struttura meccanica?vedo molte parti mobili in attrito tra di loro con notevoli sollecitazioni....

[ChrisLuxembourg]

If only "Felix" could see this...

[dodje22]

tis engine is doomed to fail because of the mechanical parts.

it's like a caterpillar waiting to unjoin won if its links as in a rotary engin there are only 2 component's

SUPER-EFFICIENT ENGINE Newest Design

[qotsaandsoadfan1]

Quasiturbine works well on an animation ..but thats as far as it gets. why further complicate what the wankel does already? Dr Felix put these variations in the bin for a reason..they simply dont work.

[Pavouk106]

Wankel is one nice engine. I would like to have it, because it's something unusual. But where to get one?

[cressylovin]

@Pavouk106 u'd have to get a mazda RX series car....only mazda makes the rotaries currently. they're interesting...fast and high revving, but low on the torque and not so great on the fuel economy. also generally not as reliable in the long run.

[qotsaandsoadfan1]

@cressylovin i disagree, i have owned my rx3 13bT for 4 years and not one problem has occured, as for fuel economy its no worse than my 5 litre v8 holden pushrod boat anchor of an engine and as for torque its really not an issue when the car only weighs 820kg - 900kg with me in it. i think it all comes down to how it is maintained just like any engine. the "rotaries have no torque " and "rotaries are unreliable thirsty cars" are catch cries of rotary haters . please dont buy into it.

[cressylovin]

@qotsaandsoadfan1 as i said, its more of a generalization. the newer mazda rotaries are quite good reliability, but in the long run of over 300,000kms the rotary cannot stand up in reliability - this is just inherent to their design. saying that a small rotary is no worse than a '5 litre v8 holden pushrod' says something about fuel economy...but hey its a sports car, who cares.

yes they work well on low torque as the RX series are quite light cars. the engine is suited to the car.

[qotsaandsoadfan1]

@cressylovin 300.000Kms is a dam good run for any engine. and i agree with you on most and as i said about economy i know by displacement they are thirsty but i look at the amount of power output, the v8 has aproxximately 220Kw and the rotor 217kw both about the same on fuel but my rotor leaves my v8 for dead there is just no competition the rx runs low 11's on pump fuel and im not even going to bother running the holden it would just embarrass me on the quater mile.lol so i agree mostly :)

[cressylovin]

@qotsaandsoadfan1 yeah i think i'm just getting at that its a totally different animal. you really can't compare a standard piston engine to a wankel. honestly i like aspects of both. i dont know if i i would ever want one myself or not, its hard choice:)

[Pavouk106]

@cressylovin Hey, I know that, but where to get money to buy one :-D They are not really cheap. But I would like to have it :-) Not so much people have car/motorcycle with wankel ;-)

[fairyheli2]

steam turbine ftw!

[circusboy90210]

it took 30 years and the mind of a japanese man to perfect it. being the wankel.

[LuisNunez210]

I own a HOnda with a 3.0 V6 VTEC and a 1984 Mazda RX-7 GSL-SE with a13B 1.3 Rotary Motor and the Mazda BEAST the 3.0. Sorry but I have to go with ROTARY!!!!

[Dnaracer01]

@LuisNunez210

I drove a 160HP 1.4 TFSI Scirocco 3 and a new Mazda Rx8 with 231 HP...

The scirocco goes better ...

If the Wankel would have more ccm and more tourqe, than it would be better. but the RX8 need much fuel.

[DrifterX34]

@LuisNunez210 You're probably driving an Accord. Accords just weren't built to be sporty. Because if you were driving an NSX then you would know that the racing feel of the NSX beats the hell out of the '84 rotary engine any day. Maybe if you had a '95 RX-7, that would be more reasonable to choose the rotary engine. Don't get me wrong, I love rotary engines, I just don't think you can compare an '84 sports car with a modern day family car lol

[musclekid13]

@LuisNunez210 Everytime man

[gpower88]

@LuisNunez210 you probably not talking about the nsx right? if yes u gotta be kidding!

[SoloFantasy]

Quasiturbine is superior in every way. speaking from an Mechanical engineer point of view.

[oiseautempete]

from a mecanic point of view, the Wankel works (see the Mazda RX8...), the Quasiturbine not: that is the difference...

[SoloFantasy]

How does it not work, they demonstrated it. they do need to tune and prefect it for sure.

[oiseautempete]

Quasiturbine work? I NEVER see one REALY works as gasoline engine: the only functional prototypes run with air or steam . I read for long time (8 years) with Sir St Hilaire and point the problems: very high frictions (hard to start), bad formed combustion chamber (same as the Wankel= bad combustion efficiency), low crank arm (low mecanical efficiency), same tight and lubrication problems as the Wankel ...i see nothing new...

[jiggahippo]

what is the differents? Please explain why u feel one is better than the other. Im learning.

[oiseautempete]

@jiggahippo I think you know how the Wankel works (excentic triangular solid rotor), but the quasiturbine works to yet only with steam or pressurized air, not as gas burning engine : too much problems, specialy with the deformable rotor : too much friction, overheat, bad lubrication,and the dissymetric forces cause lockages...

[jiggahippo]

wow, so what do u feel is better, rotory engine or piston for high RPM's running for long extened time?

[oiseautempete]

@jiggahippo

The Wankel is ok to run at high power level: he's used by many high speed aircraft homebuilder, and at constant RPM, the fuel consumption is only 15% higher as a piston engine, and without vibrations...You know that the French car maker "Citroën" build a helicopter in the 70'? the engine, a trirotor wankel Comotor (association Citroën/NSU) and the chopper fly very nice and economic (in comparision with a turbine).Project down with the dissolution of Comotor in 1975...

[Tala2n]

The difference ? A Wankel engine works really !

[Phayish]

I don't understand. The animation starting at 1:46. I don't understand how the shaft is able to keep spinning, if the compression happens at the top of the chamber, how it is going to keep pushing the shaft clockwise? I can understand this in an everyday I.C.E., but not this new quasiturbine engine..

[UTUBPLEASE]

The Quasiturbine is a phony rotary engine.

The face plates reciprocate back and fourth.

They are using the old scam artist technique

of telling a truth (Wankel) and then telling a

lie (Quasiturbine).

[yontopapa]

I am sure the "Motor Rotativo Yonto 3", here in YouTube, is the best Rotary Engine.

[spring74light]

I spent years devising ways to repair and rebuild NSU Wankel engines. Perhaps I should have got out more?

There was nothing QUITE like a Ro that would not start! (I can imagine now greyed heads nodding in agreement at that observation!)

[Tyneside, England]

[spring74light]

P.S. I was busy rebuilding a Wankel one day when an interested visitor turned up at my workshop.

"How often do these engines seize up, then?" he enquired.

"Once," I replied!
