Holy S*** We've Come A Long Way!!!
 

The first rotary engine

Wow. Looks just like the Renesis!

sweet find!

what are you smokin?

No cigar.....
 

Not even close to the first rotary!

Maybe the first MAZDA version, but perhaps we should step back and see how far Mazda went.... what they got when they bought the license from NSU was a suitcase full of bits. Not even a running model, just an 'idea'.

and Felix was out of the picture-.

doc

^ is that Mr. Wankel? Wankel somethin. the true inventor or the rotary engine. Like he made the first succesful one.

Yeah, Felix Wankel.

And the engine DOES look just like a Renesis. The stuff hanging off the front might be different, but the engine is only the little keg like part in the middle of it.

well, it was mazda's firs t engine!

If you want some real info... Do a google search for KKM

i dont think so

ya, no shit eh?

Prepare for the biggest rotary engine.
 

The biggest rotary engine ;)

Come to think of it, that picture does look like some kinda post-apocalyptic hash pipe...

that looks nuts

thank god for the rotary

aaahaa looks like one out of waterworld or something

Re: Prepare for the biggest rotary engine.
 

that is awesome

That's pretty big. The biggest one though was described as having a rotor the size of a dining room table and was large enough for a full size adult to stand in the housing.

The first succesful rotary engines were slightly different than the ones we use now. They were called type kk something and the eccentric shaft was FIXED and the whole housing rotated and the rotor as well, inside another bigger housing. This created less stress on the eccentric and could rev higher than 20,000 rpm. The drawback was that you had to disassemble the engine to change the spark plugs! I believe this is the engine shown in the picture with Felix, look how there is a housing withing a housing. Cool!

MyRxBad said this earlier.

And Felix Wankle didn't actually have the idea of the rotary engine in its current "KKM" form. I read a very interesting "history" book about it, and one of his associates came up with the stationary housing and rotors/eccentric shaft KKM design. Felix was really pissed-off, because the new design was not perfectly balanced with true circular motion like his original DKM design. I suppose he eventually came around - the rest is history...

There is a really neat animation of the DKM somewhere (I just spent 1/2 hour looking for it - d'oh). Although not as simple as the KKM, you can see how smooth it would have run.
