Found digging thru some of my old Rx history books.
Started in 74, supposed to be released in 77.
Model R160b
Specs. Engine. 16b 1598cc/110ci
Compression. 10.2:1
Output. 198bhp(net)@ 6500rpm. Single turbo JDM only. No Usa version to be offered.
Torque 192lb-ft @3300 rpm
Drivetrain. 5spd Manual
Steering. Standard Recirculating ball. Turns. lock to lock 2.9 Turning circle. 26.5ft.
Wheelbase; 87.2 inches.
The most unique design was of course the engine.
it had what was called quadrotronic rotors. 4 sided rotors in a rectangular design. With the
intake sides being larger for greater air intake and hp.
It had a center eccentric shaft along witht he regular one. similar to todays balance shaft motors for smoothness.
It was driven off a auxillary gear attached to the oil pump system.
5 port design with 5th port for higher velocity of air flow at upper rpms trying to avoid the turbo lag.
Yhis was controlled by what seems a funny terminology. Wankalator valve.
Fuel was delivered by Bosch Fuel injection system with 8 injectors designed to pulse with the 4 sides of the rotors. Instead of being jet-tronic it was called rotronic injection
Dist and ignition circuit were as the following.
2 distributors and 4 coils. Dist being of course the dual point systems. With 1 coil per pulse of the rotor timing.
0-60 times were projected at 6.5 seconds with 1/4 times of 13.5/101.2 mph
Top speed estimated at 155mph being limited to body design at final gear ratio.

 

Interesting stuff. Too bad nothing ever came of it.

 

The article was written before my time. Im sure this guys, doctor, is in senior housing and got nothing better to do. I bet he takes viagra 3 times a day.

 

agreed.

 

LISTen UP SoNNY, they got me on an Viagra DRip along with a seperate sedative DRip so i
can get all my proper Up's and Downs exercise.

 

rectangular rotors???? I need a pic....

 

Wow thats crazy. Where did yu get this info from?

 

Anyone wanna buy a slightly used WANKALATOR VALVE?

 

You had me going until the 4 sided rotors... you need an ODD number of rotor faces...

 

And I bet you NEVER roll out of bed in the middle of the night with the blue veined kickstand on duty !

 

I don't think you do. I'd love to hear why though.

 

another victim of the 70's fuel crunch.

 

Hmm... well if you think about the inside of an oil pump it has four faces. But I don't think the combustion cycles would line up (i.e. one rotor face goes by and it is doing compression and the next one goes by and wants to do exhaust). I'd like to see working links to pictures of exactly what Mazda was up to, assuming this isn't actually a prank

 

Wankel had many star type engines he was developing, the reason 3 faces became standard it was less costly and mechanically complicated.... but that doesn't mean they couldn't be built...

BTW, I thought only Dirt Was Older than you Wackypappy... !

 

Try to get some more info or pics or somthing im quite interested. Ill post up anything that i find.

i want pics dammit. this is kinda twisting my brain now.

 

LOLOLOLOLOLOLOL.... nice doc!

 

There's no way, the ellipsoid chamber would have to be closer to circular. This sould then lower the volume void at time of intake while increasing the volume of the void at time of ignition. The shape of it wouldn't allow for adequate compression. Off quick math, i'd say you'd get like 6:1

 

I've seen this design principle before, somebody was touting it as new but I cannot recall the name/url of it.

 

^If you're thinking about the quasiturbine engine, then you are mistaken. They are two completely different designs.

 

read that at some point the rotary motor was going to be put into a domestic car...

 

dates........

 

drugblock has information on that...i will ask him to post the info in here...

 

no i mean, look at the date of the last post before yours.....
