Mazda Rotary in Action

[311ZeroCool]

Rotaries will be back as before, Mazda was working on a 1.6l version that has much better fuel consumption. Plus changing to a direct injection system with pulsing (lase) plugs would stop one of the major heat issues they have. There are 10 developers on the rotary and 10000.... on the piston motor, give the motor time. As we move towards New fuels and Hybrids the Rotary may server to be a light weight power plant for them.. ask Audi!

[FuLLeFFekT1]

@Philipahearn123 Wrong. FELIX Wankel.

[FuLLeFFekT1]

@barringtonlevy555 Yeah, too bad the Germans never go it to work as good as the Japanese did.

[halflifemasta]

1.3 L with fuel consumption of a 3.5 v6 and performance of a 2.0L

[Tuminatuh]

They forgot to show the part where the pressure builds and blows the apex seal...

[DieselTurboDog]

@Tuminatuh and they forgot to show them putting oil into it every week from how much oil consumption this engine has.

I bought a speed3 not as pretty as the Rx8 and not RWD but more power!!

[tonycstech]

i imagine allot of shak'n

[matteo15100]

faster faster!

[MrOTTOMAN66]

MAZDA HAS SAID THEY WILL QUIT MAKING THIS ENGINE IN 2012, SAD.

[Tuminatuh]

@MrOTTOMAN66 It's no longer revolutionary, nor necessary, to keep producing the rotary engine... not when you have lil 4-cylinders about the same size that make as much power and get better fuel economy.

[chlb29]

@MrOTTOMAN66 noooooooo

[HawkZachary]

@MrOTTOMAN66 That wat kind of engine they will make? :(

[MrSnakeaholic]

@MrOTTOMAN66 so rx9 will come with a V8 :P and 5,000$ less lol

[cowskater5]

so what do they say the literage is?



[rondawg420000]

Amazing

[Tj1056]

once they figure out the best seals then the rotary is going to be a unlimited power sorce!

[jdmjon1991]

I own a rotary still amazes me how a triangle spins in a box,but oh well learning about it is fun

[122ffsdd]

mazdas with rotary engines have the highest power to weight ratio of any production car?!

[Philipahearn123]

Dr Frederik Wankel Invented it.

[fmflores2000]

But will it blend?

[jefries123]

@fmflores2000 hahaha with one huge as blender, maybe one with a rotary powered engine..

[96infinitii30]

no power they are slow . cool concept though

[MuRdUrFaCe420]

good luck finding a mechanic thats gonna work on that

[MannyFresh1x]

why are these being used today is their some type of flaw or are they to expensive and what about the super chargers and turbochargers can they still be added to motos to gain horsepower

[Reynard13Fuchs]

@MannyFresh1x They are almost exclusively used by Mazda but you might find some aircraft with Wankle Powerplants.

Many 'piston only' people will cite a ton of 'flaws' with Wankles, notably the possibility of a fractured block around the spark plugs from overheating. This 'flaw' however, can happen to ANY engine.

They are highly efficient and burn all of the fuel that enters them. But, they burn a LOT of fuel as well.

Turbo and Superchargers have been used on them.

[MannyFresh1x]

can someone give me an opinion of how these are better than traditional combustible engines

[peteypie26]

@MannyFresh1x they're alot smaller and lighter than other engines generating the same power, as well as reaching a higher RPM, I've had a 13b (non turbo) and it was a great engine, had a straight through exhaust system with 2x 4" back boxes, it sounded awesome

[dapsapsrp]

@MannyFresh1x Compared to reciprocating piston engines back in the day rotary engines had a much higher power to displacement and power to weight ratio. One of the original engines used in the RX-7 was only 70 cubic inches, barely over a litre, but produced 100 hp. This was during 80's when engines 5-6 times bigger barely produced 200 hp or less. They were, however, short lived and prone to oil burning and leaking. A Mazda rotary was usually spent at 80k-100k miles.

[dimesach]

@dapsapsrp haha lucky to get 20,000 miles at a time without a problem

[quezadaquiroz]

@iluvincitingviolence yea germans created the engine but japanese mad it fit in a car man so technically they created something from scratch!!:D

[logelamutp]

german engineering

[CyberGTX09]

@logelamutp

Japanese engineering, bro.

[iluvincitingviolence]

@CyberGTX09 I suggest you read up on who created the engine in the first place. The Japanese really only do one thing well...take someone else's idea and make it better.

[MrFrankyfourfinger]

@CyberGTX09

Who invented it? Do not believe that it was a Japanese surname with the Wankel said.

The rotary engine was invented in Germany

[AJunboxings]

man there like a two stroke little and very powerful

[cadw600]

How many rotors are in the engine of an rx-8?

[hailfire82997]

@cadw600 2

[buttmanroad]

Nice!!

[AndyRock1]

@TheRacingwits well first stop and think about the word cylinder... it refers to something of cylindrical shape... did you see any cylindrical shaped objects inside the motor?

[JasonMann8]

i need a screensaver of this

[danijlew]

@TheRacingwits: or by adding forced induction, lighter rotors, etc... you don't have to add rotors to add power.

[MakeEmSayUnh]

Rotary engines are cool. The only problem is when they break, nobody knows how to work on them.

[GR3TSCH3]

invented in Germany ; )

[fil892]

@GR3TSCH3 improved by Mazda, in Japan ;) !

[TheForza1000]

@GR3TSCH3 ; Yes and used in Audi R0 80 as you probrably know, but as usual it has been cloned by the Japs and improved so a rebuild is not neccesary until at least 60,000 miles..tip wear etc.

[VenomXtacy]

It is the equivalent to a 6 cylinder piston engine. 2 rotors x 3 sides. Each side of the rotor goes through the 4 stroke cycle like a piston engine (Int, Comp, Comb, Exh.). Each side of the rotor spins 1/4 of a revolution per stroke. Every 4 stroke cycle in this engine spins the crank 3 times as opposed to the piston engine which spins the crank 2 times for every 4 stroke cycle

[FantasticMRmike]

@TheRacingwits its a two rotor, there are no cylinders in it, only way to add more power is to add more rotors!

[thereisthespoon]

wow... it is amazing how some people just look at this at the expo and keep walking without wondering about it!

[DeeFRecords]

japaneese art. specialist on technoligy and other constructions, love em the onlyone that actually CAN make cars, sleds\snowmobiles (yamaha) and so on you got my full attention and respect.

[barringtonlevy555]

@DeeFRecords yea, too bad the rotary engine wasn't invented by the Japanese, but by a German ...

[madjimms]

@barringtonlevy555 Just because one country invents the DESIGN doesn't mean they engineered a GOOD version of it...

[cuteshadowKIA]

And still sealing is the big con of the Wnakel design, they should develop it much further, its design is as old as the normal piston engine...

[drifz1]

would they not get worn down real quick

[stichy420]

@drifz1 The engine has Oil injectors, that adds a small amount of oil to the rotor housings to keep everything lubricated inside. Some people (including myself) run pre-mix (2-Stroke Oil, Like in a motorcycle) in the gas for extra protection.

[IBLOWN]

Thats like 10,000 rpm sor sure.

[musclekid13]

I'm totally doing this when I replace my old engine!!! It'll be on display in my living room ahah

[OmarBhoo]

Such a great engine, and fascinating to watch.  wish I could get one in something other than the RX8.

[000ADRush]

@OmarBhoo rx7. older. alot faster though! alot cleaner engines to

[techhighPROJECCCCTTT]

@everyoneaskingaboutturbos

They can have turbochargers and superchargers, but mazda is yet to use them in any of their models AFTER the rx-7

[faffaflunkie]

How does it turn the crankshaft?

[ottolote93]

@faffaflunkie the rotating block is connected to the crankshaft, but not to the crankshaft's surrounding gear.

[311ZeroCool]

@faffaflunkie it's not a crankshaft it's an E-Shaft : "Rotors both rotate around the eccentrics and make orbital revolutions around the eccentric shaft. "

[ImDanimal85]

My life is now Complete.....

[24nov67]

they drink fuel like a 3.5 use gallons of oil and get very warm into the bargain.

[peppermintfreak1]

zoom zoom...

[ferchos360]

it work like a 3 piston engine

[1993TMAXX]

@ferchos360 well there actually 2 triangular peices, one on the other side also, so its a 6 piston engine

[1993TMAXX]

@ferchos360 no, there 2 rotors so its a 6

[drbaltazar]

i got one question!will mazda use way stronger material for the gear ring in the piston

(more rpm)since this is the only reason a rotary is locked low is because the material used there is too weak to go above 9000 rpm!

[av8rdav]

@drbaltazar That is not what limits a rotary RPM. It's rotor to stationary gear contact. But mainly eccentric shaft wobble. The e-shaft between the 2 rotors starts to wobble at high RPM. Also, since there is no cool intake charge in the combustion chamber, heat is a problem.

[chivas100x100]

@Firelife3 232 hp

[badasspaintballer]

these just seem like they would create so much friction. I dont know about them.

[TheTVLicence]

The Wankel engine invented by German engineer Felix Wankel in 1957, is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons and wasting energy.

An Ingenuous design, you've gotta hand it to the Germans when it comes to engineering guys. How about a Wankel engine with a turbo or super charger fitted to it and running on HHO or a Nitro boosted gasoline fuelled engine, now that's something I'd love to see!

[kkursor]

As my friend who owns RX-8 says, though the engine volume is low (1.3), it eats absolutely enormous amount of fuel (25L of 95 octane gasoline per 100 km). I prefer my Lada 2109, which has 1.5 engine with 77 hp, but eats less than 8 L of 92 per 100 km =)

[swodo82]

@kkursor The volume of a 13b is actually 3.9 litres. Mazda just claim it is a 1.3.

[swodo82]

@kkursor The total swept volume of a 13b is actually 3.9 litres.

[marbrel]

best enginer mechanic

[fightingforlacy]

who the eff comes up with this sorta stuff? its mind boggling looking at it.

[shopdawg85]

i would love to see the 20B in action...tri rotor rotary motor

[RScar311]

@shopdawg85 how bout a 26B...quad rotor rotary motor

[submanup]

i want an rx-8 with one of these so bad... cool cutaway nice vid

[MEDIRTBIKEMASTER]

if u seen a rotary moter in a RX7 its soooo small and yet it packs a huge punch i know this cuz i have a RX7 FC3S

[gxryd3r]

@MeLoVemY350z no pistons needed, less moving parts

[nephosis]

@gxryd3r "no pistons needed, less moving parts"

... That would be *fewer* moving parts. 'Less' is used for things which are measured not counted, like water and air. 'Fewer' is the correct word here. Fewer moving parts, indeed, is a good thing.

[anu606]

i wanna see it at 9000 rpm

[320iguy]

@anu606 It goes over 9000!!!!

[dacasman]

thats the coolest cut-away ive ever seen!

[jt8fan7272]

Wow! Everytime I see the inside of the rotary it still fascinates me. It sure is cool owning a car that has this as it's power!

[thegliderguy]

@jt8fan7272 Until it breaks and you need parts ;)

[thegliderguy]

@jt8fan7272 Until it breaks and you need parts ;)

[TheReasonWhyGuy]

@jt8fan7272 cooler than piston power... though personally I'm a fan of electric motors, I still love the rotary motor :)

[rockondon]

yeah thanx i bought a 93 rx7 yesterday for

8000 with a rebuilt motor,i was wondering

what it looked like inside ?thats really awesome

[adiomang]

boo yah! i bought a 93 rx7 about 3 weeks ago for $5000, 3 cheers for rotary power!

[flodeezul]

enjoy :)

[jet62095]

@rockondon How many miles?

[openhousespanish]

Very nice!!

[n00ber420]

nice display

[youtert]

It's like someone took a Spirograph and turned it into an engine.

[stearmer]

wow
