Manufacturing patents in different countries

The engine is a very important part of the "three big pieces" of the car, and its technical content directly determines the popularity of this car. We started reform and opening up in the 1980s. The earliest joint venture car companies appeared in the 1980s. For example, SAIC Volkswagen and FAW-Benz are the first batch. Everyone is very familiar with SAIC Volkswagen. After all, it still exists, but what is FAW-Benz? Isn't it Beijing Benz now?

When FAW wants to introduce luxury brands into the domestic market, the first thing that comes to mind is Mercedes-Benz. Later, FAW-Benz was established, and about 200 cars were put on the market. As FAW has no engine technology, it wants to buy one from overseas. In this way, it acquired Saab, together with its engine technology.

FAW wanted to install Saab engine for Mercedes-Benz, but Mercedes-Benz refused. Since then, FAW and Mercedes-Benz have parted ways, and these 200 FAW-Benz cars are "out of print". Later, FAW and Audi set up a joint venture company, and Audi also agreed to install Saab engines on the same models they launched. After the launch of the model, the performance of Saab engine was "delayed" and Audi engine was re-equipped.

After all, isn't this tortuous detour because our engine technology is weak? Many joint venture brands did not have the ability to develop engines at the beginning of their establishment. In desperation, they have to purchase from overseas brands. At first, German brands did not intend to export engines to us, thinking that this would reveal engine technology. We contacted Japanese brands, and Mitsubishi Motors agreed to export engines to domestic brands after voting by the board of directors.

The Japanese media are very worried about this and feel that Mitsubishi is "selling technology". Mitsubishi said: China can't build Japanese engines in 50 years, because all parts of Mitsubishi engines are finished products, and there are no high-precision machine tools in China. Even if the engine is disassembled, the performance of one-to-one copied parts can not meet the minimum standards of Japanese engines, and the fuel economy is far from the same. Moreover, even if the same engine is produced, a large number of patents can't be bypassed, and these patent fees are a headache for domestic car companies.

If we don't change the battlefield, we will still compete with overseas brands in the field of fuel vehicles. Even in a few decades, we can't compete with others. This is not to underestimate ourselves. People have studied engines for more than 65,438+000 years. Can they catch up in a short time?

Fortunately, we take the development of new energy vehicles as a strategic goal, which is "changing tracks". For the three major power systems, the technical level of all countries in the world is similar, and there is no big lead. As long as the layout is early, the planning is good, and some policy help is provided, why not do something important? For example, if consumers choose new energy vehicles, they will be given price subsidies, exempted from purchase tax and exempted from licensing fees. In some cities with limited license plates and numbers, if you choose new energy vehicles, you will not be restricted by license plates and numbers. It is a good way to drive the development of the whole new energy vehicle market through these big cities with high economic level.

As a result, the vigorous new energy automobile industry, driven by the policy, is like standing on the tuyere, and soon develops to a certain scale. At present, the market penetration rate of new energy vehicles has exceeded 30%, which poses a great threat to fuel vehicles. A number of models with relatively close prices and strong product strength have emerged in the market.

For example, the popular Thunder just listed has good strength. The new car * * * launched a total of seven models, with a price of 654.38+02.99-229.90 yuan. The car is built on the EMA-E electric drive platform, positioning a pure electric compact SUV.

Personally, I think the listing of this SUV is of great significance. The price range of 654.38+0.3-0.23 million yuan makes pure electric vehicles no longer unattainable. If it is lower than the compact SUV of the joint venture brand, it is not difficult for consumers to accept it. Secondly, the original pure electric vehicle is either too expensive or too small, which does not meet the car purchase budget of most people. Small in size, it is not suitable for home use. However, the popular Thunder is a compact SUV with a length of 4600 mm, a width of 1860 mm, a height of 1680 mm and a wheelbase of 27 15 mm, which can meet the household needs of most people.

Third, friends in the northern region may worry that the cruising range of pure electric vehicles will shrink in winter, while the popular Thunder is equipped with Huawei's heat pump management system, which can increase the cruising range by 65,438+06% even in low temperature environment. Therefore, its cruising range is relatively real, and there is not much "moisture".

Fourth, the armored battery carried by popular thunder has undergone various rigorous tests, and it is not afraid of bumps and fires, so it is very safe.

The intelligent and technological level of new energy vehicles is obviously stronger than that of fuel vehicles with the same price, and the popular Lei is no exception. It enhances the sense of science and technology through two 10.25 inch "dual screens", and the color and resolution of the screens are very good. Functionally, its car has built-in HMI2.0 interactive system, which supports satellite navigation, voice recognition control, car networking and Bluetooth/car phone. Some models also offer L2-class assisted driving system, automatic APA2.0 parking and 360-degree panoramic images.

Configuration, such as collision warning, driving fatigue reminder, panoramic sunroof, electric tailgate, keyless entry/start, leather steering wheel, leather seat, 6 speakers, LED light group, automatic air conditioner, etc. It also appears on different configuration models. In addition, the car is also equipped with a crystal electronic lever, and there is also a popular "lion" logo in the crystal, which enhances the recognition and luxury of the interior.

Thanks to the long wheelbase design of the popular Thunder, its rear row space is very spacious. An experiencer with a height of1.78m sits in the back row with more than one punch in the head space and more than two punches in the leg space. The seat design is also spacious and soft, which can bring a good ride experience. In addition, its trunk space is also very large, and the rear seats can be laid down, which expands the practicality of the trunk and can load large items.

In terms of power, the car is equipped with a front motor, with a maximum power of 150kW(204 HP) and a peak torque of 340 N m. The power output is equivalent to that of the mainstream 2.0T engine. However, due to the characteristic that the motor can burst into peak torque as soon as it is started, its acceleration experience is stronger than that of the 2.0T engine.

In terms of battery life, the car is equipped with 57.8kWh and 85.9kWh lithium iron phosphate armored batteries, and the CLTC pure electric cruising range is 430km and 630km respectively. Its battery pack supports fast charging, and it only takes 0.58 hours to charge to 80% of the maximum power. It also supports the dual discharge function of 220V V, and you can watch movies while camping.

A reporter asked elon musk, CEO of Tesla: Who do you think will be the car companies that threaten Tesla in the future?

I think it will come from China, Musk said. China has a complete industrial chain of new energy vehicles and a large number of car companies with competitive and technical strength. I respect China Automobile Company.

From Japanese companies' "China can't make Japanese engines in 50 years" to Musk's "I respect China car companies", it fully reflects the importance of technical strength to the automobile manufacturing industry. You will be beaten if you fall behind. Only by staying ahead can we gain the respect of others. It is precisely because of "Wei Xiaoli", BYD, Dongfeng Fengxing and other car companies that our technical strength has made a qualitative leap in the new energy era. What do you think of this?
