single rotor motor
neone know of a company that makes these?
|
Why? I know that there was a single rotor motorcycle once, but I have never heard of one in a car!
|
i have a few friends up at PSU that r gonna try to build one. just trying to find a company that makes them so that i can get so specs for them.
|
Hmmm, I will try to find the company name, but there is a company in England that builds custom rotaries. Sound like a cool idea!
|
I think Hurly Engineering sells them, but they are $20K+.
I'm making one this summer out of half a 12A. Going to have a machine shop cut down the eccentric shaft. |
Check out Hayes Engineering, or possibly Atkins Rotary. I am not sure which one is doing it, but one of them makes a single rotor engine. They also make marine engines, and are researching rotaries for military use.

I don'nt know if i'm suppose to say anything, but i do know that Pineapple is building a motor that suppose to put down some serious hp. I'm talking SERIOUS HP. Drop him an e-mail. CJ

look in ebay under wankel .......they use to put them in snowmobiles and chainsaws:p:

What applications are you considering for the engine? Go-Kart? Riding Lawnmower? Either way, fill me in! :D |
The NSU Spider (world's first production rotary car) had one, as did the Suzuki RE5 motorbike, but I'm pretty sure that's it for production vehicles. Mazda actually supplied a few single rotor versions of their motors (called 6A and 7A) for NASA to use in target drones years ago. But the best one I've seen is the single rotor Curtiss-Wright developed in the 60's to power large pumps and generators. It had a capacity of 1920ci or 31.5L and made 782hp @ 1525rpm! :D

Atkins rotary does

Here's a photo of the rotor out of that 1920ci engine. The other rotors are other developmental engines, one a bit bigger than a 13B, the other about half the size.
|
And here's a photo of the world's smallest rotary engine, made by O.S. Engines inJapn for model aircraft. It's just 5cc and makes an amazing 1.27hp @ 17,000rpm, that's 254hp/litre! It's 70mm in diameter and fits in you hand. I've seen a photo of one in a RC car, but apparently the power made it undriveable! :D
|
Oops, forgot the photo! :p:

NZ, I'm in love. Thats beyond :mspank:
anymore of the freak wankels? I personally wouldnt mind having a 21a |

i meant the 21a monster
never produced, all made but pockets in the rotor sides. I have a picxture of it in my yamaguchi book. |
Am i the only one who looked at the rotor housing of the model engine and wondered "those ports are so tiny, I don't have a Dremel bit small enough to port them"? :D
- pj (never satisfied with stock) |
Racing Beat i think had a full size 150hp single rotor engine. if anyone still has a cataugle from them it was in the very front
|
I think it would be cool to make a single rotor say 13b size and then p port it and put it in a shifter super cart. you could make at least a 100 hp and it would be small and light weight and mabe a little bit fast too. hehaaea.

I've seen ultra lights with single rotor motors, but i don't know where they came from. this was before i had an interest. Funny sounding....like one hand drumming

WOW so much info thank you guys/gals. i didnt think neone would bother replying.
|
sorry but the os is not the smallest rotary eng ........there is a rotary eng developed that is smaller than a PENNY .....if you are curios to see pics i belive its in monito sites
|

|
I'd like to see it power my electric shaver too!

At El cojon speedway in california they have weekend events with single rotor rx7s that race in a oval track. Like once a month I think... Seems cheap to do.
|
NZConvertible, that is not the smallest rotary engine. The smallest rotary was made in San Francisco. It is 1 or 2 inches in diamater, and they are used to recharge the batteries for laptops.
