Why did the Wankel engine fail?
Emissions: The unburnt fuel, along with burned oil (described below) both result in terrible emissions from Wankel engines. The emissions problems are one of several reasons the RX-8 was pulled from production. Failing apex seals are the primary cause of rotary engines going down for overhaul.
Is the Wankel engine dead?
The Mazda Rotary Engine Is Finally Coming Back The last production car to use the unique powerplant was the RX-8, and that car was cancelled all the way back in 2011. Now, the rotary engine is officially returning to Mazda’s lineup—as a range extender for the automaker’s first electric vehicles.
Is the Wankel engine German?
The German engineer Felix Wankel, inventor of a rotary engine that will be used in race cars, is born on August 13, 1902, in Lahr, Germany. Wankel reportedly came up with the basic idea for a new type of internal combustion gasoline engine when he was only 17 years old.
Why is the rotary dead?
Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the exhaust. Finally, emissions are poor and fuel economy is terrible, and ultimately this is the cause of it’s death.
Why didn’t rotary engines catch on?
The fundamental design flaw of having a moving combustion chamber as on a rotary also means that part of each fuel charge is still burning when it gets fired down the exhaust, meaning wasted energy, increased fuel consumption and dirty emissions, not helped by the necessary total loss lubrication system which means oil …

What kind of engine did Sachs Wankel make?
(LINKS FOR SACHS WANKEL SERVICE MANUALS ARE AT BOTTOM OF PAGE) My first true passion and hobby was rebuilding engines. Oddly enough, the first engine that peaked my curiosity was the OS 49PI type 2, a 4.97cc single rotor wankel engine intended for use in model aircraft.
When did the Wankel engine become ” news “?
The Wankel engine became “news” when NSU Motorwerken, where Felix Wankel was an engineer, developed a dual-rotor engine for use in its 1967 NSU Ro 80, which was a modest success.
