A piece of Domestic Rotary History
I wanted to share a piece of Domestic Rotary nostalgia with the rotary community...
What rotor has 5mm Apex seals, dual rows of side seals, 1700cc of displacement, and is made of cast iron?
I look forward to your guesses. This came from a running engine design, however it never made production. (See attached photo... More to come).
Answer to follow...
Enjoy!

I think sonicrat is right i found a pic.

"It's a lesser known fact that Chevrolet acquired a licence for the Wankel engine in 1970. Two and four rotor engines were built and mounted mid-ships in experimental cars.
The XP882T used two rotory engines bolted together to produce around 400bhp
They went on to get Pininfarina to style a new Corvette around the engine as they considered production options. Various two and four rotor, steel bodied and glass-fibre bodied Corvettes were worked on until 1974 when retiring GM president Ed Cole suspended rotary engine development due to emissions difficulties. Research was halted completely in 1977.
Thats the only USA car i could find

getting Warm!!
You guys are getting VERY close to the truth.
I will post the answer with a couple more photos of this acquisition this evening.
I really am enjoying the interesting research and facts you guys are sharing with all of us, though!

Ford. A friend of mine's dad actually has three or four Ford rotaries sitting in his garage. I keep meaning to get pictures of them. His dad actually was on the r&d team when Ford was trying to develop their rotary plans. Exciting stuff.

THE ANSWER
Without further adieu,
Here is the answer on the source of this wonderful piece of Rotary engine nostagia, directly from the person whom I acquired it (from the horses mouth you might say, although I am sure he wouldn't appreciate that reference
)
********************************************
"...the rotor was from Chevrolet's effort to mass produce a rotary to be used in the Chevrolet Monza. The Monza was designed specifically for the rotary application.
The engine was near production ready when the plug as pulled. And it wasn't just emissions. As I said last night it was also fuel economy.
The effort was essentially ended when Ed Cole retired. I'm not sure he had a say in the decision.
G. M. Engineering Staff continued a small rotary development effort after the Chevy program was discontinued.
I'm of the opinion it was mostly window dressing..."
********************************************
I was also told that GM injected transmission fluid as the combustion seal lubricant rather than the engine oil as used by Mazda to make life easier for the emissions control devices. Perhaps one of the origins for the ATF trick??

Part of the reason behind GM's decision to not produce the rotary-powered Monza was that Mazda was suffering under the perception that the rotary was unreliable, due to the early failures of the carbon-seal motors, and for a US maker to put one in a car would lend credibility to the design. -WG
I actually heard that it was a propaganda campaign by the "big 3" that was saying that the rotarys were unreliable and worthless, and it was all because they couldent get it right.
Damn American car companies....

Another interesting thing, is that, looking at the two rotors, one would tend to think that better spin-up could be achieved by making the generating radius smaller, but having the rotor be thicker to take up the slack in displacement, thereby decreasing the overall rotational moment of inertia of the engine. Just a thought. Port design might become a problem, though, with a really thick rotor.

I also heard something about a rotary powered Mercades?? does anyone know anything about this???

Here is a pic of the non-production C111.

It was powered by a 4 rotor 300+hp Wankel.

This engine is similar to what was installed in Felix Wankel's personal SL. Cool eh?
