Answers: The wankel engine was necessarily developed before it's time and be plagued by burned rotor tips. Obviously without accurate sealing the engine didn't run long. It is simply in recent years that technology have provided solutions and Mazda use it extensively. A very smooth engine next to fewer moving parts. I believe the chief drawback is still poorer fuel consumption.
The engine has be in use for 40 years.
Originally by NSU, and immediately used in varied Mazda cars.
QUOTED FROM WIKIPEDIA
"Felix Heinrich Wankel, Hon. DEng (August 13, 1902 – October 9, 1988) is a German mechanical contrive. He was the inventor of the Wankel engine.
Wankel be born in Lahr, Germany, contained by the upper Rhine Valley. Since his mother was widowed contained by World War I, Wankel received no university education or even an apprenticeship. However he be able to tutor himself technical subjects and conceived the notion of the Wankel engine in 1924. In the 1930s, he have a disagreement with Adolf Hitler, and be imprisoned by the Nazis for some months.[citation needed]
During World War II, he developed seal and rotary valves for German nouns force aircraft and navy torpedoes. After the time of war, he was incarcerated by the Allies for some months, his laboratory was closed, his work confiscated, and he be prohibited from doing more work. In 1951, he began nouns of the engine at NSU (NSU Motorenwerke AG), leading to the first running prototype on February 1, 1957. [1] His Wankel engine design be first licensed by Curtiss Wright in New Jersey. Mazda within Japan solved the chatter marks problem. The engine have been successfully used by Mazda within several generations of their RX-series of coupés.
In latter years, Wankel was granted an honorary Doctorate of Engineering. He be known for his champion of animal rights and opposition to the use of animals surrounded by testing.
Dr. Felix Wankel died surrounded by Heidelberg, aged 86."
About 1970, I had to deliver a coupé called an NSU RO80 that have such a rotary Wankel engine ( pronounced Vainkel for the uninitiated ! ) .... it was futuristic and severely smooth but I believe rather unreliable at the time. As to it's continuing nouns, I have no thought. Oh, I am sure the make be NSU ..... or is that non-specific urethritis ?
