Post by: Al Smith on March 12, 2012, 08:07:48 am: The Wankel never worked out .It seems the exhaust was prone to setting the woods on fire .

The engine design it's self had problems .Early on the sealing rings would fail plus the fact the engine in general was not made as a high torque type design .

They made power as a result of high RPM's much like turbine . In the car application they were not very friendly regarding gasoline consumption .

Perhaps had the design had been further developed it could or in fact may prove to be something .As far as I know it was pretty much shelved .
