@offspringfanman96 did you really just ask that? What does more work? driving at high speed for a while...as in a constant motion like a rotary or like a piston...floor it, let off, floor it, let off
LOL DID YOU JUST SAY 8000HP LOLOLOLOL STUPID AMERICAN PIECE OF SHIT! LOL EIGHT THOUSAND HORSE POWER! AHHAHAHAHAHAHAHHAHA thats like going mach one you idiot, reaching that horse power is Humanly, Physically impossible. Think before you type buddy, I'll let that one slide for now cuz Im laughing my ass off. HAHAHAHHAHAHAHAHAHHA Eight thousand HAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHHAHAHA how big are the turbos? Like the size of a 5 year old? How bigs the block? like 99999999.9999Litres or something?
people like you make me cry honestly i wanna laugh at you as much as you laughed at gullfsk but Ive just come to realize that its not morally correct to laugh at mentally challenged people like you......... HAHA!!! lol sorry had to do it, physically impossible huh??? really??? i think i found at 9999999.999999 litre block!!!!! HAHAHAHA!!!!
actually buddy, YOU should think before YOU type but obviously people like you wouldnt know that top fuel engines are 8,000 hp, cuz all you fuckers do is talk shit when you dont even know wat the fuck ur talking about. go look up NHRA Dragsters and learn a thing or two DIPSHIT.
Actually, rotary's suck lots of gas too. The new RX-8 is only 1.3L, and is rated at 16 MPG city and 22 highway. Turbocharge it or supercharge it, and it gets just as crappy gas mileage as a V8.
A boosted engine should not lose enough gas to matter at the pump, unless you're some street light racing kid who floors it every time you see a green light. These engines are apples and oranges, you can't do a direct comparison like that. "OMG THIS ONE IS SMALLER AND WORSE IN MPG"...yeah, just doesn't work. If you are calling it a 1.3L in a comparison, then you do not understand the "rotary math" to show it's true displacement.
well im using an old rx2 twin dizzy in my datsun, never been opened or ported and is still runing fine so if u treat it well it treats u well. so stick it up ya arse all you's saying they dont last long well 36 years later and its flogging the likes of new cars today. eat a rotor
When I did my apprenticeship I was told these are the most reliable engine! Mainly due to people putting them in small airplanes and not having much trouble them up in the air!
lol, I haven't heard of them having overheating problems for a very, very, very long time. My brother just last week bought a 1985 RX-7 with like 235km on it or something like that. It doesn't overheat and runs fine. Actually, I was a little concerned because the coolant temps were staying so low, and I knew they were supposed to produce a lot of heat, but it doesn't.
if its staying cool that's good but yes they do overheat because they came with shitty radiators that leak and then you find yourself in traffic overheating and your coolant seals blow my opinion is to get a new all aluminum radiator on it asap strictly as a precaution I had my 1993 twinturbo rotary blow the coolant seals because of that so yes they do over heat and yes you can prevent it.
i think people should step back and just look at how cool it is that at least one company was willing to go out there and try something different in engine configuration
Why rotary engines are cool: -Crazy horsepower per liter potential -Less vibration -Only a few moving parts -Super high rpms -Lightweight Why rotary engines suck: -Fuel suckers -Oil suckers -Short life expectancy -No torque Don't flame me, I know a guy who works in a rotary-specific garage and was out having drinks with him and his boss once when he showed me his new tattoo of a rotor. I said "That's cool dude, but it'll be gone in 75,000 miles!" and they got a real kick out of it.
they are meant to be run at 3k to 6k rpms this keeps carbon from building up in the combustion chamber. Also they have sensative coolant seals which is why they must never EVER overheat. They are very effective for racing because they are light produce power and they last longer the harder you run them and have none of the friction problems of piston engines. So remember run em fast keep em cool and they'll last 150k plus remember its a motor meant for a race car so u have to treat it like one.
yes but fast revs harm a piston engine no more who makes it the point is u can rev the rotary as much as u want. Plus honda never pushed 255hp out of a 1.3 L
@ButtPoopWiggle Agreed, except for one part, "-Oil Suckers" There are plenty of cars that burn more oil than a rotary. I've owned 3 Fcs and one Fe, they burned less oil than my mitsu and GM... The difference? When the rotary burns oil, it's working properly.
I seem to remember when they put rotor engines on bikes, the Japanese screwed about them because they were pissing over their piston engines in racing!
Depends on what you like doing! Some dude up silver stone put a truck turbo on one of these! it didn't boost up till about 5000, but when it got going it was putting just under 600bhp on the wheels! it wasted everything on the track that day!
it's not a diesel and stop trying too comare it to a v8 it's more like a motor bike engine you show me the v8 production engine that can rev to 13,500rpm
this is a very dim-witted comment... yes, rotarys have low torque.. in LOW RPMS... the trick to driving these efficently is to your revs always in the powerband.. cause if you shift too soon.. your gonna end up below the powerband in the next shift.. and you'll be out of synch.. but the rotary excels far beyond that of a cylinder based car if in the right drivers hands.. its takes a real pro to bring out the hidden potential of a rotary... i love my s14.. but i LOVE my FC
If thats true, then why does all of the RX8 opponents win in car comparisons? the main rival, the 350Z walks all over it, time and time again...and its not my "personal" opinion, its a literal fact. wanna compare facts? You also say that the 8 will have higher torque driven faster? ive seen them raced and 350Z's still walk all over them, so your point holds what? sooo, why buy something like this, expecting it to be something its not. And thats Fast, because its not. and not reliable either.
maybe you havent heard.. but all rotary fans declare Rx8 SE03 is fail.. theres alot of factors your skiming out on.. like the 350z is built more powerful from the start.. i would gladly buy a Z33 over a SE03.. in a straight drag or whatever i have no doubt a VQ35 could out run a 2 rotor rotary.. you have to look at it in other ways than just some 10 sec race.. i dont really wanna start getting into too much physics.. (continued)
say in autocross races.. when you have to slow down and downshift, the Z33 will lose its powerband and start from below it even with heel and toe but the rotary tends to have a tolerant powerband that allows drivers who heel and toe to stay inside even when they turn and power through in that high torque range. like i said.. it depends on the driver.. there are quite a few variables that could stand between two cars winning a race.. rotarys are differnt.. neither is truly better, only preference
i understand what your saying, the only time ive seen rotaries catch up to opponents is when the road gets curvy...because the rotary is lighter then a conventional engine, an the power-to-weight is perfectly balanced, but when the curves flatten out, the faster car once again, picks up speed. The way to keep the rotary in its peak powerband is through high RPMs, but with the power it produces its easily outmatched. If the rotary produced 50 more HP then we'd be in business. No?
yup.. that's hitting it on the head.. and the RX7 FD did just that.. the RX8 SE has less horsepower than the FD and many people look at the Renesis rotary as fail compaired to the classic 13b.. but when so alot of people switch out the 2 rotor 13b with a 3 rotor 20b.. its like going from V6 to V8 but the increase in weight is so small, its hard to notice.. because RX8 abandoned the B series engine, its not looked upon to favorable by alot of fans..
Although the newer RX8's have less power then the previous 7's reliability has vastly improved correct? ive read numerous reviews on the 8's better build quality because of no forced induction, so for them to squeeze 232hp from the rotary is pretty impressive and making it more reliable is even better. Im looking into an 07' manual maybe to buy ...im unsure of how the flooding of the engine happens? can you explain how it happens? afterall, id need to know how something works before i buy it
no, rotary just have lower torque, its the design of the engine, small moment arm means it's hard to get torque out of them, however, it will spin hella fast.
Correct, Felix Heinrich Wankel is the founding father of the Rotary concept, he did shower the world the 1st ever prototype on Feb.1st 1957, Mazda only took the idea and and made it better working out all the kinks and chatter mark problems. So to say the japanese invented it? is absolutely false...made it better yes, but inventing goes right to Felix Wankel. And as why other companies gave up is because of the V8-like MPG and insane amount of oil consumption.
Invented is one thing, refining & solving the issues rotary have and put it into a production product is completely another. GM, Toyota, Mercedes-Benz and i think few others all tried to use this design & all of them gave up. Only Mazda was dedicated & persistent enough to improve & refine the engine all these yrs & i think they should be applaud for. By simply saying they didn't came up with the original idea then completely ignore Mazda effort for me that's unfair & hollow.
Wankel thought of the concept of the rotary engine. it was the Japanese who spent millions of dollars developing it. using there brains to figure out all the problems. Next you'll tell me Isaac Newton is from Europe so gravity is European.
I think that the I.O.Rotary Internal Combustion Engine from Philistia Industrial Group and which everybody can watch on Youtube is the ultimate rotary engine . It consumes only 40% of the amount of fuel consumed by piston engines for equivalent power and torque output !!!!!
The future engine is here . Soon we will be able to replace existing engines with this new rotary engine . And new cars will be built with this engine within .
using a wankel without a turbo is kinda stupid. a wankel engine was a low compresssion ratio, resulting in poor mileage; a turbo, by increasing the amount of air going into the engine basicly increases that ratio to something much more acceptable.
A guy who sells performance parts out of japan told me that the rx8 is a 1.3L turbo rotary engine. And that if it was just rotary it would have like 40hp and that it had to be turbo rotary in order to get the 238 horsies. He said its a built in factory turbo. And to increase your HP by 25 or so u can change the factory turbo PSI settings up a few PSI and safely increase your HP from your stock engine. Thoughts? I looked around not sure what to think? thanks guys
To set the record straight. The first ROTARY engine was used in aircrafts back in the late 1800´s. But like Browndog1978 stated, the first WANKEL rotary engine, same concept but different layout was used on MC´s and then cars.
So rotary and wankel are not the same thing but the same idea, just different layouts.
ehh.. the first idea for wankel came from finland, but because they thought that the idea was too absurd they sold the idea to the japanese who started to develop it :)
Lada only started working recently on the rotor motor. wenkel of germany was first, but as we all know mazda bought the rights and the rest is history.
Hi, does anyone knows where can I get dimensions of a rotary engine parts. I need them to make a 3D model of such engine as a project for Autocad class. Thanks!
My RX7s engine went at 82,000 miles. One of the seals failed and put mega pressure into the cooling system when the go they go. Water and steam all over the place lol. Got a Z after that.
Umm no it was Germany and Japan. Invented by a german motor engineer, attempted by Mercedes and even GM for production, but in the end, ultimately refined beyond belief by the Japanese. This engine design is only around today because of 1 company, and we can thank Mazda for that :)
Not true. Not anymore. There are many Rx-7's with 200k miles on the original engine. The first Wankels used carbon apex seals, and those, indeed, needed work at about 80k miles. Sometimes you could prolong the inevitable by pouring a bit of oil into the carburetor...
I know this question is a bit off the wall but if I were to stick a 2 rotor in a buggy, say 800 lb rally buggy, with 5 speed tranny, would the rotary engine take massive abuse or would it be just fine? Rotaries are light weight and like high rpms so it should be fine right?
actually the biggest problems with rotary engines are the coolant seals which are made of rubber. of all the parts of rotary engines they are probably the weakest link. the apex seals are more durable than most people give credit for. people are just used to being able to abuse their piston engines with awful knock, the apex seals won't take that abuse.
for rotary engine, 1 stroke equals to 90 deg of rotor rotation (270 deg of eccentric shaft rotation), 2 rotor rotary engine has a power stroke interval of only 135 deg of eccentric shaft rotation
yes it does for every 1 rotation of the rotor it fires the plugs 3 times. on a piston engine for every 1 rotation it fires the plugs once. there are 4 cycles in a both but the rotary does all 4 in 1/3 rotation
No... He is trying to say that it is a 3.9 when it isn't. When you measure how big (liter) an engine is you measure how much volume the engine displaces for 1 revolution of the crankshaft.
The displacment of a 1,3l rotary engine is only 2,6l and not 3,9l. A wankel need 3 eccentric shaft rotation for a complet Otto cycle. 1080° (3 ) for a Wankel and 720° for a four stroke piston engine.
But since there are 3 chambers per rotor, essentially you have 3 cycles completing each 3 ecc. shaft revs. You only have to wait for 3 whole revolutions when you first start the engine and all chambers are empty.
...therefore the equivalent of a power stroke is realized with every crank rotation per rotor (as opposed to a power stroke every 2 rotations of a piston engine's crank) this is why rotaries are compared to piston engines twice their size.
Sorry if these questions are covered by the vid, I have no speakers for my computer. First off, does it compress and combust on all 3 sides of the rotor in the same cycle, or only on the one? Also, I heard that rotory engines are high maintainence... Are they really, or is that just piston-engine fanatic propoganda?
They are actually very low matianence, the problem is finding a mechanic who knows how to work on them usually. They tend to have the seals go if you boost them too much, but they're fairly easy to replace. They almost never 'break' down.
Thanks for this

Correct, Felix Heinrich Wankel is the founding father of the Rotary concept, he did shower the world the 1st ever prototype on Feb.1st 1957, Mazda only took the idea and and made it better working out all the kinks and chatter mark problems. So to say the japanese invented it? is absolutely false...made it better yes, but inventing goes right to Felix Wankel. And as why other companies gave up is because of the V8-like MPG and insane amount of oil consumption.

germans do make it. Dr Felix Wankel is the original inverntor, and he was german. The japanese just put it in there mazdas thats all

hey numbnuts, all i said was wankel invented it. and the japanese used it in their mazda. so wtf are you talkin about
NoRotorNoMotor114 3 years ago
Invented is one thing, refining & solving the issues rotary have and put it into a production product is completely another. GM, Toyota, Mercedes-Benz and i think few others all tried to use this design & all of them gave up. Only Mazda was dedicated & persistent enough to improve & refine the engine all these yrs & i think they should be applaud for. By simply saying they didn't came up with the original idea then completely ignore Mazda effort for me that's unfair & hollow.

NoRotor is right. it is actually called a wankel engine, as opposed to a piston engine...therefore, Felix Wankel invented it.

The rx8 was designed in California so it an American car with a German engine produced by a Japanese company? things are getting confusing.

designed in California... so what?
Design has nothing to do with the engine.
Nopiw 3 years ago
I never said it did.
But if you if you would like to argue.
Wankel thought of the concept of the rotary engine. it was the Japanese who spent millions of dollars developing it. using there brains to figure out all the problems. Next you'll tell me Isaac Newton is from Europe so gravity is European.

I think that the I.O.Rotary Internal Combustion Engine from Philistia Industrial Group and which everybody can watch on Youtube is the ultimate rotary engine . It consumes only 40% of the amount of fuel consumed by piston engines for equivalent power and torque output !!!!!
The future engine is here . Soon we will be able to replace existing engines with this new rotary engine . And new cars will be built with this engine within .
Very simple and very economic engine !!!!

using a wankel without a turbo is kinda stupid. a wankel engine was a low compresssion ratio, resulting in poor mileage; a turbo, by increasing the amount of air going into the engine basicly increases that ratio to something much more acceptable.
eltabby 3 years ago
A guy who sells performance parts out of japan told me that the rx8 is a 1.3L turbo rotary engine. And that if it was just rotary it would have like 40hp and that it had to be turbo rotary in order to get the 238 horsies. He said its a built in factory turbo. And to increase your HP by 25 or so u can change the factory turbo PSI settings up a few PSI and safely increase your HP from your stock engine. Thoughts? I looked around not sure what to think? thanks guys

To set the record straight. The first ROTARY engine was used in aircrafts back in the late 1800´s. But like Browndog1978 stated, the first WANKEL rotary engine, same concept but different layout was used on MC´s and then cars.
So rotary and wankel are not the same thing but the same idea, just different layouts.

Felix Wankel, the inventor, was German.
The first usable Wankel engines were in motorcycles produced by a German motorcycle manufacturer called NSU.
Many manufacturers produced cars and bikes with rotary engines fitted, including GM, Citroen Mercedes-Benz and Suzuki with their RE-5 motorcycle.
Mazda just happens to be the only one still using the rotary.

Umm no it was Germany and Japan. Invented by a german motor engineer, attempted by Mercedes and even GM for production, but in the end, ultimately refined beyond belief by the Japanese. This engine design is only around today because of 1 company, and we can thank Mazda for that :)

Not true. Not anymore. There are many Rx-7's with 200k miles on the original engine. The first Wankels used carbon apex seals, and those, indeed, needed work at about 80k miles. Sometimes you could prolong the inevitable by pouring a bit of oil into the carburetor...

I know this question is a bit off the wall but if I were to stick a 2 rotor in a buggy, say 800 lb rally buggy, with 5 speed tranny, would the rotary engine take massive abuse or would it be just fine? Rotaries are light weight and like high rpms so it should be fine right?
AkinaGod 4 years ago
should be.
fewer parts usually means fewer headaches.
the usual rotary problems are the casing and rotor,and rotor apex seals.
nakazatoGTR 4 years ago
actually the biggest problems with rotary engines are the coolant seals which are made of rubber. of all the parts of rotary engines they are probably the weakest link. the apex seals are more durable than most people give credit for. people are just used to being able to abuse their piston engines with awful knock, the apex seals won't take that abuse.

therefore the 2 rotor rotary engine cc is equivalent to 1962cc. so that's why they are rated 2litre in some country.
ahblu3 4 years ago
654cc per rotor, 2 rotors make up 1308cc in actual.
ahblu3 4 years ago
for rotary engine, 1 stroke equals to 90 deg of rotor rotation (270 deg of eccentric shaft rotation), 2 rotor rotary engine has a power stroke interval of only 135 deg of eccentric shaft rotation
ahblu3 4 years ago
relative rotor velocity is one third of eccentric shaft's angular velocity relative to the housing.

yes it does for every 1 rotation of the rotor it fires the plugs 3 times. on a piston engine for every 1 rotation it fires the plugs once. there are 4 cycles in a both but the rotary does all 4 in 1/3 rotation
darkblaze176 4 years ago
thats why the actual cc is 3 times bigger than what it is marketed. 3 times spark 3 times the fuel 3 times the cumbustion. so 1.3 = 3.9
rps13sr 4 years ago
It is not a 3.9... The crank shaft spins 3 times for one rotation of the rotor...
sheeblue01 4 years ago
read the post again...hes talking about capacity
browndog1978 4 years ago
No... He is trying to say that it is a 3.9 when it isn't. When you measure how big (liter) an engine is you measure how much volume the engine displaces for 1 revolution of the crankshaft.
sheeblue01 4 years ago
oh..yeh...sorry. You are right
browndog1978 4 years ago
The displacment of a 1,3l rotary engine is only 2,6l and not 3,9l. A wankel need 3 eccentric shaft rotation for a complet Otto cycle. 1080° (3 ) for a Wankel and 720° for a four stroke piston engine.
KKM57P 4 years ago
But since there are 3 chambers per rotor, essentially you have 3 cycles completing each 3 ecc. shaft revs. You only have to wait for 3 whole revolutions when you first start the engine and all chambers are empty.
stfoo 4 years ago
...therefore the equivalent of a power stroke is realized with every crank rotation per rotor (as opposed to a power stroke every 2 rotations of a piston engine's crank) this is why rotaries are compared to piston engines twice their size.

Sorry if these questions are covered by the vid, I have no speakers for my computer. First off, does it compress and combust on all 3 sides of the rotor in the same cycle, or only on the one? Also, I heard that rotory engines are high maintainence... Are they really, or is that just piston-engine fanatic propoganda?
wraith444 4 years ago
It fires (power) in one location, the other locations are carrying out the intake, compression, and exhaust strokes.
KanzlerM 4 years ago
But each side combusts every time it reaches the spark?
wraith444 4 years ago
They are actually very low matianence, the problem is finding a mechanic who knows how to work on them usually. They tend to have the seals go if you boost them too much, but they're fairly easy to replace. They almost never 'break' down.
