The engine still has 8 cylinders. I couldn't find anything on the amount of HP or torque it puts out.

It's still in testing but it works. The President of the company is someone we all know... Carroll Shelby.

so, he's the one who finaly steped up to the plate to produse that....

it is almost a cross between a wankle and a radial eng.. verry compact, very low internal losses etc.. been in prototype stages for about 10 years.. i remember reading about it back when i was in tech school.. awesome setup, and its modular.. ie: you can stack them for more power.

from what i remember displacement per " modual " was 1.0L, hp was around 300 torque was also around 300, fuel economy was expected to be exelent, and able to chug down to about 200-300 rpm...

thats pretty cool.


Torque
Another unique feature of the OX2 engine is that it achieves considerable torque at all stages through its operating range. Consequently, in most engine applications there would be no need for the engine to operate at revs higher than 2,500 rpm. In some instances, this would eliminate the need for a gearbox and would certainly reduce engine wear. However, in particular applications, if high engine revs were mandated, the OX2 engine could easily be adapted accordingly.

yup.. I've been following it for a few years now. They used to have the torque and hp ratings on the site but they don't anymore. With the light weight and awesome power band it would be great in a crawler.

looking at the animation, it looks like it would be hell on mounting. I wonder if it would produce large vibrations, I am sure that they will be MUCH less than say a bigblock v-8!

So what's the hold up? And the site still says "estimated good fuel economy"?


Sheesh... if they have actually built them, and run them... they should have hard and fast numbers.


Looks like hooey to me....

Looks a lot like half a DynaCam engine. Same idea anyways. Axial pistons driving a sinusoidal cam kinda like some A/C compressors. I know they've been in development for 10 - 15 years at least. I think they've got it certified for aircraft now.

200 hp @ 2000
650 lb/ft @ 1200

Interesting I havent heard of this before ,,, After reading the info and looking at the pictures it appears to operate in princeable like a Sterling engine.. but with a rotating piston ring. very size efficent... I want one for my Subaru....

does it look like the engine is hooked up backwards to the ax15 looking transmission in this picture?

It looks like a rotory AC compressor to me.

This is the specs of their highest torque and horsepower engine. It's their turbo charged model.... :(

"It has initiated preliminary testing of a turbocharged version of the OX2 powerplant and the test results are positive. AET's OX2, design level two, engine #2, generating 145 KPA of boost, created 215 lb ft of torque, resulting in 30 horsepower at 735 rpm, an increase of 80 lb ft of torque and 13.2 horsepower over its previously tested normally aspirated version."

30 hp and 215 lb ft of torque ??? Whoopty fawking doo!!!

I does look cool but it's a loooooong way from being anything usable or generating any kind of demand.

i have seen alot of engines over the years that did generate interest and were definitly useable, but something happened to end it all, oil company? goverment? we may never know.

and seriously, 30 HP at 715 rpm? sounds pretty good to me, how much HP is your engine making at the rpm you really use it? 70-80 tops weighing 8 times more?, think about it.

unfortunately, i see this engine going down the drain just like all the others before it, but i hope i'm wrong.

30hp who cares.... even with the weight advantage... you STILL with the new RRCA rules gotta be 2400lbs(probably) .... if there were no weight limit yea.... it'd be more benfical but 70 hp at 700 RPM would be bout perfect i think.... toppin out at 200 and weighing in at 125 lbs.... now we are talkin.....

woah! :eek: KILLER!

I Love technology!

Weight restrictions don't diminish the advantage of this motor... having freedom to place the weight where one chooses is still a huge advantage!

If I read right, this motor can be stacked in modules, so 1/8 the weight of a smallblock, even with the 30 hp and 215 lb quoted above, is still promising. Give me 120hp and 860ft-lb of torque at half the weight, and I'll still be grinning! If the thing is air-cooled (looks like it!), that's even more weight saved and better simplicity...

I hope we keep seeing more of this kind of freak-tech... it makes the breed stronger... CTMs trickled down from competition to the trail, what will be next?
