OK, so Wankels do have eccentric 'stroke-like' fundamental features, compared to say, a turbine, & each rotor breathes/fires each rev cycle...like a 2-stroke... also breathe through cyclicly revealed ports, & so they do sound very like a 2-stroke...
Methinks the old 'quack like a duck/waddle like a duck...could it be a duck' may well apply here -or at the very least - it is suspiciously Daffy-like.
 
In fact, perhaps '2-cycle' would cover it, dynamics-wise & also cut out semantic/tribological conflict - some..
 
Two strokes and wankles like the 'Wanx' Norton fire on each 360' cycle. Some turbines take pulses of fluid to turn them instead of constant flow. So the wankle could be called a pulsed 2 stroke turbine.
 
The "Highly successful Norton Collectables" accessories mentioned above we found leftovers from at the Norton/Shenstone factory auction in November 2003.... Marketing the Norton name and logo has to date not been all that successful, I guess. :oops:
You need a mass production of motorcycles that every granny has heard the name of and will grab the T-shirt bearing the name when she goes shopping for the kids. Now did I hear somebody murmer "Harley"? THEN you can successfully merchandize! :mrgreen:
 
I received a catalogue of "Highly successful Norton Collectables" via Classic Bike magazine at the time. The marketing idea seemed simple enough, just stamp the word 'Norton' on and double the price.

A Norton Rotary ("Wankel") has four phases per revolution of the rotor: induction, compression, expansion, exhaust. Now why do I Simpleton believe this makes it a four-stroke? Probably because the textbooks tell me so....
 
The rotor rotates at 1/3 the speed of the eccentric shaft, each face of the rotor produces one power pulse per rev of the rotor. (there are three faces) So at 9000 RPM the rotor is producing 9000 power pulses. Two rotors equals 18,000 power pulses at 9000 RPM. It might not be a turbine but it's about as close as it gets. The exhaust pipes do get very hot though. One of the Shropshire NOC branch members has one with the proper extractor exhaust. He passed me on my Rotary like I was in reverse. The complete exhaust pipe was orange, not dull cherry red.
Last year's Shropshire branch camping weekend raised 6 Rotaries, one Commando and an ES2. (this years was poor with only 4 Rotaries and a Commando)
 
INDEED .

the piston ( :shock: :lol: ) CYCLE is refered to as 2 cycle & 4 cycle , here we have an Icycle ( :D :lol: :oops: ) :P

ER , the revolution of the piston ' chambers ' would indicate the cycle . wether the suck squash bang blow are seperate occurances or overlaped . Perhaps .

Would appear to be FOUR SEPERATE operations / Cycles , Thus Four Cycle . only things strokeing are the rotor seals , & they contiuously revolve no cycle / stroke . So if you want to be awkward , its a one stroke or infinity stroke , as it keeps on indefinately . Perfect reliability at last . :P :D
 
Or not, since each discrete crankshaft revolution produced is by a complete cyclic firing/breathing sequenced rotor,sans 4-cycle phase/wasted moment routine [no matter what eccentric evolutions the gubbins perform] hence 2 cycle...
It makes no difference in principle if there are multiples of rotor sets, the crankshaft still turns 360`...
 
A single shot gun might be seen as a one stroke engine, & a blow-back machine pistol [smg] as a 2-stroke?
The combined/sequenced firing/expulsion/reloading is also analogous to the rotary, like-wise [Gatling gun?]
 
A Norton Rotary is my dream bike. Any Norton Rotary will do :)

I was looking at importing a Commander from the UK but the cost to import was going to be more than the bike.

The closest I can get at the moment is that I own a Commando (and a half) and have owned 3 Mazda rotaries.

I also have a Suzuki RE5 rotor and eccentric shaft sitting in a box at home.

Nearly a Commando


I have epitrochoid on the brain and a rotor on my leg :)

In fact... any non conventional engine astounds me. I have a pulse jet as well. The wife drives a boxer engined Subaru... now to find a radial engine :)
 
Now , a Rotary Rotary , or spinning wankle could solve any cooling problems , If Not any Noise issues . :mrgreen:
 
Did you notice the $5000 twin cylinder 700cc 'mini-sprint ' motor on that web site turns out 165 horsepower ? Could be good in a road race sidecar ?
 
Did you check out their custom crank builds? Maybe they could do a custom all-roller bearing unit suitable for a Commando?
 
Matt,you make a good technical point about what is a true 'rotary' mill, wherein the crank is stationary/fixed & the rest rotates..
Wankel originally designed his to do like-wise, & in the German, he does not describe his machine as a rotary, but as an orbital piston device.
I think the desciber term 'rotary' has been [mis] applied to avoid royalty type penalties by Toyo-Kogyo/Mazda, when they should be properly called "Wankel"
- as per "Diesel'' .
