how does rotatory engines work?

[challengestradale]

hi you there? do anyone have a page or something so i could understand how does this engines work?

and if this are the same of boxer engines

thanks!!!!

damn TT beat me to it again :P

They are soo different from boxer engines.
just check out the site TT posted also look on there for Horizontally opposed engines for how a Boxer engine works if you don't know.

No offense but personally I think that this engine sucks cos its never reliable and its costly 2 maintain...2ndly a Piston engine has mroe torque than a rotary so in acceleration it'll lose out....3rdly is the sound...these 3 points are enough 2 convince me so....

But it does have its advantages as well. Its size means that it can be put closer to the CoG of the car and thus it improves the car's dynamics. Apparently they are planning to come up with a quad rotor turbocharged version of the engine for the RX-8, that should solve the power problem.

rotary motors are perfectly reliable as long as they are taken care of, 99% of the time people who say they are not never actually owned one, i have had 4 or 5 rotary powered vehicles, and some eventually had over 200k miles on them without a hiccup

for info on the how it works, goto www.howstuffworks.com
they have a good animation and explination

rotary motors are great cause they are more balanced than a piston engine, they alos have fewer moving parts
and the sound is great
one of the best sounding cars i have ever heard was the le mans winning 787B rotary race car, it had a R26B 4 rotor motor pushing around 750hp....and the thing sounded so great i have a vid with it reving and making lots of niose....

[Daggernite]

dont forget the rotary engine in a RX-8 is only a 1.3 but still knocks out 240BHP!! Impressive I think, Fuel consumptions meant to be a downfall tho

Hmm then it doesn't add up...cos my friend who owned a FC3S sold it off....too unreliable and thirsty for fuel.....maintainence is VERY expensive....in the end he got an EVO and was way more impressed with it

[PaulGT2164]

well he must have not taken care of it very well if it was unreliable, and the maintainence here in the states isnt expensive at all

but oh well generally speaking they are reliable, but like every car ever made, some just arent built well

but every rotary car i have owned/worked on/etc has been great

[sergei_dekker85]

well if it was that good then It'd have made its way into production cars...which is not the case....the only advantage i see is that it makes the car more balanced cos its compact and its smooth....and in my country It'll save a HELL lotta $$ on road tax (how much u pay is based on the displacement of the car)

heres a good site about the renesis mazda engine.

220Nm of torque from a 1.3 and about 170hp per litre isn't too bad....

With a combined MPG of 26mpg and rotaries renoned for eating oil i wouldnt buy one though

[PaulGT2164]

"rotaries renoned for eating oil i wouldnt buy one though"

rotary motors "eat" oil because they squirt oil inside the rotor housing for lubrication, so its not a problems, its a feature lol

"well if it was that good then It'd have made its way into production cars"

because of the emissions, bad fuel milage, and the oil consumption
piston engines are better for an everyda economical point of view
but just cause they are not used widely doesnt mean they are a bad engine, the rotary motor is a great engine, and for its displacemnt has always been a freat performer =)

Check out this website http://www.rotaryengineillustrated.com/animations.html. There are a bunch of videos, cutaways, and diagrams illustrating the rotary combustion process.

In the 60's,70's and 80's rotaries weren't very efficient or clean. But with today's technology they far outshine typical internal combustion engines in terms of power to displacement ratio, and they're much cleaner now. I wouldn't hesitate to own one.

what is the gas mileage on a RX-8?

heh.. nice bart simpson on google pic. was just thinking of something like that.
(kinda reminds me of the search button post)

[Skylinefreak]

Rotaries are not all that bad, but they aren't all that good either. Not very efficient but naturally well-balanced and with much less moving parts etc...

Dude, Im the biggest Rotary fan in the world. I plan on making the perfect engine someday, and it will be a Rotary Diesel engine. You all just wait and see. Listening to all of you dog on the rotary was like a dagger in my heart :( But I think that people dont see the potential that is there. The fact that they can make a 1.3 of similar or smaller size to that of a 1.3 piston engine, with over 230 hp is simly amazing.... just imaging what they could do with a 3 or 4 liter rotary?
I mean they have 2.6 liter 4 rotars that make 460 hp n/a. Thats power if you ask me....


Speaking of which I have a question. I have the increadable video that they give to the Mazda Techs when training to work on the Renisis rotary engine. It has CGI moving computer models (in 3d and gloriously detailed) that looks real, and walks through the engineering of it step by step. I have this on a CD WMP file. Is there a way I can upload this so you all can see it? If anyone knows a way, please let me know :mrgreen:

[challengestradale]

pretty amazing!!!

keep going and please keep us updated!!!
