Mazda’s 3-rotor hybrid engine plan discovered in patent filings

Had rumor belong to Mazda revitalizing the rotating motor on a regular basis since RX-8 ended production in 2012. The company itself has been pretty quiet about the rotary engine, except for a range extender planned in an upcoming future. dip into the mixture version of the MX-30. However, Mazda has filed a patent application for a three-rotor engine mixture powertrain system. And unlike the MX-30, it not only appears to be the main propulsion unit, but is also configured for a rear-wheel drive arrangement.

The patent has been filed with the European Patent Office, according to a Japanese blogger taku2-4885. One of the detailed diagrams clearly depicts a rotary engine with three housings, architecturally similar to the three-rotor engine found on the Japanese market Eunos Cosmo in the early 1990s. crank is connected to a 48-volt mild-hybrid assist system and rear axle, similar to a Japanese patent for a The coupe-like RX-Vision was discovered back in August. There is also a description of the cooling system, something hot-running rotary engines need to maintain long life.

Unlike Japanese patent applications, these illustrations are not nearly as detailed. They could be a placeholder for something Mazda might, one day, if the market and planetary forces match, want to do. Of course, the gap between that and a production car is immense.

And with the way the market winds are blowing, it seems increasingly difficult to come up with a new combustion engine, especially one that uses a design known for its hunger and passion. emissions, will be put into production. Mazda has to worry about increasingly stringent regulations on electrification and emissions, especially in Europe, to simply continue Car sales in those markets in the future. It won’t be cheap not only to develop but also for people to buy.

We wouldn’t say it’s a completely hopeless case. Mazda hasn’t given up on spinning cars, as evidenced by the range expansion plans. In addition, if Toyota The partnership yields some of the electric fruits that have allowed Mazda to survive, we could see the slim chance for a PHEV variant of this car to exist. In all-electric mode, it will still be allowed in European city centers that have banned petrol engines altogether. It would certainly need something more powerful than just a 48-volt electric motor to be a plug-in hybrid.

There are countless other factors that work against a three-rotor RWD performance car, but we like the fact that Mazda, once a dreamer, is even contemplating something like this.
