Munchen, 29. October 2015 – since 2012 after the production stop for the mazda rx-8, it had looked for a long time as if the end of the wankeltechnik was sealed. Over the decades, automakers had always attempted to remove consumption and emissions of the circle engine on a level comparable to the lifting piston engine. Most recently, audi has housed a small wankel engine as a range extender (rich extender) in the tail of a hybrid audi a1. A pioneer of the first hour was mazda – and it has remained until today. On the tokyo motor show, mazda now promised to revive the circle engine.
After the first series use of a wankel in a car, the nsu wankel-spider of 1964, mazda brought his 110s cosmo sport in 1967 as the first car with two-slice engine on the market. A spectacular sports car, in whose tradition is now probably the study of rx concept. Mazda-ceo masamichi kogai said on their presentation on the tokyo motor show: "the study sports concept by re is equipped with a wankel engine system called skyactiv r. When it goes in series, i can not say. Only as much: the wankel comes back soon."
"Much in terms of fuel consumption made"
Swivel motors are elastic, speedy, spreading and quite durable. However, the breakthrough has been denied them for decades because they have significant disadvantages in particular in the consumption of ol and fuel towards usual cylinder engines. "We have made a lot in terms of fuel consumption", underlines masamichi kogai, "because otherwise he was not accepted by our customers."
The developments of the circle engine in the house of mazda began in the early 1960s. Tsuneji matsuda, then prasident of mazdas group performer toyo kogyo, traveled personal to west germany to visit the headquarters of nsu motorenwerke ag. With the developers of the circle engine, the japanese signed a contract via a technical cooperation. Their aim was to market the largely unknown new technology and make them a broad audience to be able to act as companies with technical competence. The challenge kreiskolbenmotor was an opportunity for mazda to establish itself as a unique and independent automaker.
