Netizens have such a comment on Mazda: sell cars, make money; play with rotors, burn money; make money again, burn money again; earn/burn, earn/burn... Wireless cycling.
At the beginning of 2022, Mazda Automobile once again applied for a patented technology for a new generation of rotor engine power system, indicating that the brand has never given up research and development for this type of technology research and development .
As a miracle in the field of automobile engines, Mazda's rotor engine (Wonkel engine) with excellent high rotation performance and excellent race results, in the last century attracted wide attention from global manufacturers and users, this point should be clear to know a little bit of industry history, the rotor engine of the year the posture of the racing car, interested friends can turn right to the lady, this will not unfold.
However, the delicate body makes the rotor engine unable to be widely used in passenger cars, coupled with the tightening of emission regulations in countries around the world in the new century, this engine has gradually lost its living soil.
Mazda RX-7 cross-sectional view
In order to fully adapt the rotor engine to the new era, Mazda has also made sufficient investment in technological upgrades and electrification, and unlike the rotor engine on the previous RX-7, this new rotor engine is an electrified version, that is, the rotor hybrid system.
Front-facing rear-drive layout
Judging from the patent diagram, this system is still a typical vertical layout, which fully lays the positioning of its performance car, at least the CX-30, Mazda 3 family cars are impossible to use, the probability is still the RX series of sports cars, the worst is the MX-5 this small convertible.
Rotor engine, three chambers & rotors
Among them, the engine part contains three sets of coaxial rotors & combustion chambers, that is, the "11, 12, 13" parts in the patent diagram, while behind the rotor engine is integrated an electric drive system, that is, the "14" part, and then a relatively simple gear transmission and reducer mechanism, and then provide power to the rear axle through the central drive shaft.
Electric drive module
This design idea is somewhat similar to the P2 layout of the Ashkenazi hybrid system, such as bmw 535Le, Wrangler 4xe, etc., all of which are more fuel-efficient in hybrid mode through electromechanical coupling of the electric drive system and engine. In addition, this direct coaxial direct connection motor also has a more efficient energy recovery efficiency than the crankshaft pulley for power recovery.
Suspected drive shaft direct connection
The difference is that the mainstream cars are used reciprocating piston engines, and there are independent transmissions, and from the patent diagram, the rotor hybrid system applied for by Mazda does not seem to have a complex transmission mechanism, and the electromechanical coupling and power shunting of the motor and the engine, plus two or three sets of variable speed gears, have been able to achieve the purpose of controlling power / torque / speed.
The reason why the rotor engine is difficult to enter the civilian market is that the power output of the high rotation is not compatible with the power demand of the family car, and there are also extremely high requirements for the service life and maintenance of the parts. The emergence of hybrid technology can undoubtedly effectively alleviate the pressure on the rotor engine and make it operate in more "comfortable" conditions, thereby improving stable reliability.

Mazda RX-VISION
In short, even with the hybrid system, the rotor engine is still impossible to appear on the "grocery cart", but the future RX-9 equipped with this system may be a great threat to Porsche 911, Mercedes-Benz AMG GT, for the local tycoons, who does not want to have such a strange car in their garage that even works so freshly?
