Mazda's rotor engine is revived, and the fuel consumption per 100 kilometers is only 2.5L. Is it true or false?

1. Recently, Mazda reported some news about rotor engines. A few days ago, Mazda announced the latest power development plan, which confirmed that rotor engines will be used in the following models and a new vertical platform will be developed simultaneously.

2. Whether it is the obsession with rotor technology, the advanced performance of the Chuangchi Blue Sky engine, and the later Skyactiv-X compressed combustion engine, it has added a lot of color.Recently, Mazda announced that it would restore the rotor engine, which had been in a flash for nearly seven years.

3. Moreover, the advantages of the rotor engine are small and efficient, which is indeed very suitable for making a range increaser for electric vehicles, and on the bright side, Mazda may be able to reproduce the glory of the rotor engine in the future in the field of new energy vehicles, which is not optimistic about.

4. In fact, many people are still uncomfortable to hear that the rotor engine will be revived through the "medium" of new energy vehicles. After all, in the 1991 Le Mans race, the Mazda 787B racing car (equipped with R26B rotor engine) won the championship with a crushing advantage.

5. The rotor engine is presented again in the form of a range increaser, and the fuel consumption per 100 kilometers is only 35 liters, which can be said to be the product of the rotor engine adapting to the times.In this way, if the Mazda MX-30 with average endurance can add a rotor engine, it will still be quite good.

Has Mazda rx7 been introduced in China

1. Mazda rx7 has not been introduced into China. This is a jdm model. Mazda rx7 is a sports car under Mazda. This car is equipped with Mazda's proud rotor engine. Mazda rx7 is relatively powerful, and the control of this car is also quite good.

2. The maximum power of this engine is 195kw, and the maximum torque is 294 Nm, but the Mazda rx7 has not been introduced to domestic sales, so domestic consumers can't buy this car. Precautions for buying a car. Check the interior of the seat to check whether the seat moves normally, and close the window. Close.

3. Rx7 has not been introduced into China yet. This is a sports car owned by Mazda. This sports car uses a rotor engine. Mazda rx7 is rare in China. Some domestic players have Mazda rx7 in their hands, but most of them are basically right-hand drive cars. Of course, there is no way for such a car to get on the road.

4. Mazda rx7 has not been introduced to China. This is an jdm model. Mazda rx7 is a sports car under Mazda. This car is equipped with a rotor engine that Mazda is proud of. Mazda rx7 is relatively powerful, and the control of this car is quite good.

5. However, Mazda rx7 has not been introduced to domestic sales, so domestic consumers can't buy this car. The good news is that Mazda has a model equipped with aSub-engine cars have been introduced into China. This car is called rx8, which is the successor model of rx7.

6. Mazda rx7 has not been introduced into China, so domestic consumers can't buy this car. However, Mazda has a car equipped with a rotor engine that has been introduced into China. This car is called rx8. The engine power of Mazda rx8 is weaker, because the rx8 uses a dual-rotor naturally aspirated engine.

Which Mazda cars are rotor engines

MazdaCosmoSport is Mazda's first The model equipped with a rotor engine is also the first model in the world to commercialize rotor engine technology. FamiliaRotaryCoupe is equipped with a 0L dual-rotor engine, which reaches 100 horsepower, which is twice as powerful as the traditional piston engine.

Mazda is a Japanese car manufacturer, which is famous for its innovative rotor engine. The rotor engine is different from the traditional piston engine. It adopts a rotating triangular rotor to replace the traditional piston.

rx series car. According to the official website of Mazda Automobile, the representative model of Mazda rotor engine is the rx series. The working principle of the rotor engine is: the rotary motion of the triangular rotor is used to control compression and emission, and the combustion expansion force of combustible gas is converted into driving torque.

It's really relevant. They are all equipped with rotor engines, but the rotor engine exists as a range extender on Mazda MX-30 e-SKYACTIV R-EV, which is also a continuation of Mazda's long-standing pursuit, but its effect needs to be improved so far. .

The models equipped with rotor engines are: Mazda RX, Mazda RX8, etc.

However, Mazda is currently the only brand in the world that mass-produces rotor engine models.RX7 and RX8 have been and can be purchased in China.

Why is Mazda's rotor engine not commonly used in the automotive field?

1. Although Mazda's rotor engine is particularly powerful and does not take up space, its wearability is particularly high. It is likely that the engine will wear out after thousands of kilometers, so it is not widely used in this Mazda car.

2. The first is the maintenance of the rotor engine. The engine needs to consume oil to run, and Volkswagen engines have been criticized for many years for burning oil, but if you have seen the speed of rotor engines to consume oil, Volkswagen engines are nothing. And this is determined by the structure of the engine, and you can't change it even if you want to.

3. Due to the lack of high compression ratio of the reciprocating engine, the combustion is not sufficient, the fuel consumption is high, and the pollution is heavy. The service life of parts is short. Because the three top corners of the rotor are responsible for sealing (there are also seals similar to piston rings on the top corner), and they work under the condition of not being well lubricated for a long time, resulting in premature wear.

4. The reason for the weak power of Mazda's medium and large displacement engines is very simple, that is, it does not use mainstream turbocharging technology. Instead of improving the adequacy of combustion through pressure combustion, it is better to compress air with a compressor to improve air density, so as to make fuel more fully burned. .

5. The current lack of popularization of rotor engines is caused by its own shortcomings and environmental protection policies. It is mainly toThe following aspects: high fuel consumption and heavy pollution, which is contrary to the global advocacy of energy conservation, emission reduction and environmental sustainable development. Because there is no high compression ratio of the reciprocating engine, the combustion is not sufficient.

Which Mazda cars use rotor engines

Mazda CosmoSport is Mazda's first model equipped with a rotor engine, and also the world's first model to commercialize rotor engine technology. . 2, 2. The Fumeilai rotary coupe is equipped with a 0L dual-rotor engine, which can reach 100 horsepower, which is twice as powerful as the traditional piston engine.

The models equipped with rotor engines are: Mazda RX, Mazda RX8, etc.

In the early market, Mazda models use rotor engines, such as Mazda RX Mazda Rx, but as of August 2019, its models have been completely discontinued. Due to policies and other reasons, rotor engines are no longer produced and are really withdrawn from the market.

rx series car. According to the official website of Mazda Automobile, the representative model of Mazda rotor engine is the rx series. The working principle of the rotor engine is: the rotary motion of the triangular rotor is used to control compression and emission, and the combustion expansion force of combustible gas is converted into driving torque.

Mazda is a Japanese car manufacturer, which is famous for its innovative rotor engine. The rotor engine is different from the traditional piston engine. It adopts a rotating triangular rotor to replace the traditional piston.

MaZda RX-8Rotor Engine Model Introduction Mazda RX-8 is a two-door coupe model produced by Mazda of Japan. It is equipped with a unique rotary Wankel engine (also known as rotor engine), so it has a high reputation among car enthusiasts.

What's the matter with Mazda's rotor engine?

The rotor is triangular, and the piston ring at the three points is always in contact with the cylinder wall. The three surfaces of the rotor and the corresponding inner wall of the cavity form three combustion chambers. As the rotor rotates for a week, their volume is always changing. This structure no longer requires crankshaft and valve, and the only moving part is the rotor piston.

Because from production and assembly to maintenance and repair, rotor engines are very different from traditional engines, and the development cost is high.

The working principle of Mazda rotor engine: Generally, the piston makes a reciprocate linear motion in the cylinder during the working process of the reciprocating engine.

The space between the rotor and the housing wall is used as an internal combustion chamber, which drives the rotor to rotate through the pressure of gas expansion. Like ordinary internal combustion engines, rotor engines must successively form four working processes of intake, compression, combustion and exhaust in its studio.

High process and cost requirements. It is impossible for anything to be both a fish and a bear's paw. Because the rotor engine technology is relatively cutting-edge, the production process requirements are relatively high, and the cost is relatively expensive. Now Mazda knows and grasps this technology, so this technology has not been popularized in automobiles.

Rotor engine (Wanker engine)) The innate mechanical characteristics lead to its high fuel consumption and high requirements for manufacturing precision (the cost cannot be reduced); therefore, the last rotor engine manufacturer, Mazda, finally stopped production in June 2012.
