The birth of a rotor engine?

1. Rotor internal combustion engine, usually referred to as rotor engine, also known as triangular rotary piston engine, is a kind of four-stroke internal combustion engine, by German engineer Philly WangFelix wankel was invented in 1959, so it is also known as the Wankel engine.

2. The rotor engine was invented by the Germans. Its birth is only a direction of the evolution of the internal combustion engine. It has few advantages and many disadvantages, but it has been turned into a tragic engine by the sad Mazda. In fact, the rotor engine has been over-promoted and mythological, and the real rotor engine is unimaginable. So powerful.

3. The rotor engine was born late. In 1954, the German Figas Wanger invented the rotor engine. This engine is different from the traditional piston reciprocating engine, which adopts the rotational movement of the triangular rotor to control compression and emission.

4. Everyone must know a little about the following story. The Mazda RX family was born, and the rotor engine has become Mazda's "uninal secret".

5. The story of Mazda and Le Mans first took place in 1970, but the Belgian Leivis team, which was equipped with the Mazda 10A twin-roter engine, withdrew due to engine overheating. Until the first 58th competition in Le Mans, the champions were European and American car manufacturers.

6. The biggest technical problem is the wavy wear caused by friction with the inner wall after the engine runs for a certain period of time. After countless attempts, the problem is finally solved by integrating high-strength carbon material into the aluminum seal, which also means that the Mazda rotor engine was born.

turbo rotor engine

1. The rotor engine, also known as the turbo rotor engine and the propeller engine, is a kind of high-efficiency and low-noise engine. Its working principle is similar to that of a turbine engine, but in a rotor engine, air is compressed and accelerated through a rotating rotor instead of a hydraulic impeller, and pushed back through the nozzle to generate thrust.

2. Our general turbocharged engines and naturally aspirated engines carry out reciprocating motion, and the piston makes a reciprocating linear motion in the cylinder.

3. The differences between single-turbine and twin-turbine of Mazda rotor engines are as follows: when the driver steps on the accelerator pedal, the engine speed changes. Due to the inertia of turbines and compressors, they cannot keep up with the change of speed in time. This phenomenon is called \ hysteresis\.

How powerful is the banned rotor engine?

Compared with general reciprocating engines, the rotor engine can directly convert the combustion expansion force of combustible gas into driving torque. It replaces useless linear motion with rotation, so in theory, the rotor engine is more compact, lighter in weight, and the horsepower output will be larger.

How fast is the rotor engine?The rotor engine is banned from the original. Unlike the traditional revolving engine, the rotor engine abandons the reciprocating linear motion and directly promotes the triangular rotor to rotate through gas thrust.

The rotor engine is very powerful: the rotor engine was originally developed by German engineers, and Mazda acquired it when it saw its prospects. The principle of rotor engine is similar to that of inline engine, which is composed of intake, compression, combustion and exhaust.

The engine is different. The output shaft connected to the rotor will rotate with the rotation of the rotor itself. Eliminating useless linear motion brings many benefits. Take the twin-cylinder gasoline rotor engine as an example. Compared with the traditional six-cylinder gasoline engine of the same power, its total number of parts is about 20% less, the volume is about 30% smaller, and its own weight is reduced by nearly half.

Without Mazda and rotor engines, it is difficult to be praised and remembered by the world, and there may be miracles in the industrial field! The wear is severe and the service life of the parts is short. In terms of structure, the three vertex corners of the rotor are responsible for sealing, which cannot be well lubricated for a long time, resulting in premature wear and inability to work properly. The fuel efficiency is low, and the emission standards are not up to standard.

, the Mazda 787B with a rotor engine won the Le Mans 24-hour endurance championship. As the most famous racing race in the world, the Le Mans Championship is the dream of every car manufacturer, and Mazda became the first manufacturer in Asia to win the Le Mans Championship.

What are the advantages and disadvantages of Japanese cars? Introduction to the advantages and disadvantages of Japanese cars?

In addition, there are some domestic reasons that lead to many misunderstandings about Japanese cars. As netizens said, perhaps its biggest shortcoming is the word Japanese.

Advantages: Japanese cars are exquisite, fuel economy and cost-effective; Disadvantages: Japanese cars are cheap in materials. The economy of Japanese cars is a general concept, not only with low fuel consumption, but also low durability and maintenance costs.

Advantages and characteristics of Japanese cars Advantages of Japanese cars: Fuel-saving is well known. Compared with other power-powered cars, although Japanese cars are less powerful, their power is relatively stable. The exhaust volume of the engine it matches is relatively low, so the fuel consumption will also be lower.

Advantages of Japanese cars: complete configuration, low fuel consumption, low noise, low durability and maintenance costs, high cost performance; Japanese carsDisadvantages of the car: low safety performance, light and thin skin, cheap materials, and the appearance does not look elegant enough, which is not very suitable for commercial use.
