Rare 16b prototype unveiled
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.

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

No it's not Turbo'd
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...

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
