Lynn, you are right (as always...:)
 
Actually Wankel was rather PO when he found out what "they" = did with his engine (the one with the inside sparkplug - complete disassemb= ly for a plugchange, talk about SAG:), BUT it did run around 18000 rpm....)= .
"They" was mainly one of his engineers, I think his name was= Paschke. NSU was running out of patience waiting for Wankel's "pe= rfect" engine.
Paschke did essentially the design of the basic Rotary, and wouldn'= ;t you know it - the Renesis has just about the same layout as the original= engine - side-intake and side-exhaust!!

This is not Wankel's engine. NSU discarded his design and had to i= nduce a compressor company to give up its rights to a compressor design it = owned so as to convert that design into the engine we gleefully punish toda= y. NSU moved the stationary seals to the apex of the rotor as in Wankel'= ;s design. In fact NSU also tried to sell it as a compressor, but nobody bi= t on the idea.
 
 Wankel was a sliding seal designer during WWII and his contribut= ion was a collection and indexing of the many rotary engine and compressor = designs up to that time. His design was one that had the crank case rotatin= g at 2/3 crank speed, and other impossible features such as the spark plugs= inside the rotor. How handy would that be? 
 
Its only redeeming feature was that it performed (in theory) with pure= rotary motion. It was not useful for anything and was never produced in an= y numbers at all. The NSU Prince was the first rotary powered car. The engi= ne looking remarkably like the modern rotary. The design (originally a comp= ressor) had already been discarded by Wankel.  So, a Moped
(motorized bicycle) manufacturer NSU, brought you the rotary engine. W= ankel thought NSU had ruined his idea.
