　　　　In addition to the power upgrade, the logos of "SYLPHY" and "CLASSIC" appeared at the tail of the test car. It is speculated that the new generation of Sylphy will be launched next year.The current Sylphy is likely to be named "Sylphy Classic" and sold on the same stage as the replacement model.

　　　　Editor’s comment:Sales of new and old cars under the same roof have appeared more and more in Japanese cars. At present, most of the main Japanese cars have been introduced into China. To expand the product line, there must be more "extreme measure", such as sales of new and old cars under the same roof, or tailor-made products for the China market. Obviously, the former has lower cost and higher success rate. After the replacement of Sylphy is listed, the price of "Classic Sylphy" is expected to be lowered, and the 2.0L model will be cancelled, focusing on cost performance, and its competitiveness is still not to be underestimated.

Many friends know that the engine oil needs to be changed when the vehicle is maintained, but many people don’t know what the function of engine oil is and how to choose engine oil. Today, Xiao Jia will introduce you to the knowledge about engine oil!

Automobile lubricating oil can be generally divided into three types because of its different functions: engine oil, gearbox and differential oil, and grease (butter). The most common thing in vehicle maintenance is to change the engine oil.

Engine oil has five functions.

Lubrication function: the function of engine oil is to fill and lubricate the surfaces of moving parts and reduce the friction between moving parts. Its working principle is: the engine oil is pressurized by the oil pump and transported between the rotating parts, and an oil film is formed on the two friction surfaces to separate them, thus reducing the contact surface between moving parts, thus reducing wear and prolonging the service life of parts. There is surface friction between piston and cylinder, crank-connecting rod mechanism, cam valve train, gear rotating mechanism, etc., which must be lubricated by engine oil to ensure normal working conditions.

Cooling function: engine oil can bring back part of the heat generated between the rotating parts of the engine to the oil pan, and achieve the cooling effect through the oil pan wall. Some engines are also equipped with special engine oil radiators to achieve better cooling effect, so as to ensure the normal temperature between the rotating parts of the engine and keep the engine in normal working condition for a long time.

Sealing function: The engine oil also has a sealing function. For example, the engine piston ring and the cylinder wall are filled with engine oil, so that the contact surface and the gap have both a lubricating function and a sealing function, so that the piston can reduce air leakage when inhaling and compressing, and ensure the normal working compression ratio. If the piston ring and cylinder wall are worn, the sealing effect of engine oil can be improved by adjusting the viscosity of engine oil or adding engine oil additives, thus improving the working condition of the engine.

Cleaning function: The engine oil is pressurized by the oil pump and transported between the rotating parts of various parts for lubrication and heat dissipation. At the same time, it can also wash and clean the rotating working surface of the parts, bring the dust particles entering the engine and the garbage generated by the work to the oil pan, and keep the engine parts, rotating working surface and oil passage clean and smooth through the oil collection net and oil filter, thus ensuring the normal operation of the engine.

Rust-proof function: The working environment of the engine is complicated, and the climate change in spring, summer, autumn and winter will easily cause the metal parts to rust and deform, which will affect the normal operation of the engine and shorten its service life. The oil is pressurized by the oil pump and supplied to all parts and metal surfaces through the oil passage to form an oil film to isolate the air, which can prevent the metal surface from oxidation and rust and improve the service life of the engine.

If the engine is likened to the heart of a car, then the engine oil is the blood of the engine, which is a necessary condition to ensure the normal operation of the engine. Understanding the knowledge of engine oil, correctly selecting and using engine oil, and regularly replacing and maintaining it are very important to ensure the normal operation of the engine and prolong its service life.

　　[Global Times Comprehensive Report] German Chancellor Angela Scholz visited the White House on the 3rd local time to hold talks with US President Biden. The visit was not accompanied by any media, business delegations and cabinet ministers, and no joint press conference was held after the talks between the two sides. The media have questioned what is hidden behind this "mysterious visit". Some analysts believe that Germany and Germany are full of contradictions on issues such as aid to Ukrainian tanks, the explosion of the "Beixi" natural gas pipeline and the US Inflation Reduction Act, which is full of protectionism. However, as the "younger brother" of the United States, German leaders can do nothing about it. Germany’s "Star" magazine recently published a cover article saying that "Big Brother is back". The cover cartoon shows Biden holding Scholz, who is only half as tall, while the latter looks up at Big Brother.

　　Leave it to the public for only four minutes

　　"Mysterious visit", DPA said on the 4th that Scholz held talks with Biden at the White House on Friday, but this meeting only gave the public four minutes to observe. In his public appearance before the talks, Scholz said in English, "I really appreciate the good cooperation between us" and the transatlantic partnership is "in a very good state". Biden praised Scholz’s "strong leadership" and support for Ukraine, and said that the two countries would "help Ukraine with Qi Xin" and "keep pace in all aspects".

　　Then the two began to talk behind closed doors. The report questioned that the talks were "too mysterious". There were no consultants and recordings for the talks between the two sides, and there was no joint press conference after the talks. The report also complained that Biden ignored Berlin in his previous "trip to Europe". Biden visited Ukraine and Poland a few days ago and only made a short stop at Ramstein Air Force Base in Germany. On the contrary, this is Scholz’s second visit to Washington since he took office.

　　The Associated Press quoted people familiar with the matter as saying that the meeting between Biden and Scholz lasted for more than an hour, and the focus of the discussion was to continue to promote "global assistance to Ukraine". However, even Scholz’s senior advisers were not allowed to attend the talks. When their talks ended, Biden said half jokingly that they "solved all the problems in the world". However, the official statement issued by the two countries after the meeting hardly provided more details of the talks, and did not disclose any possible agreements or plans.

　　The secret visit and talks angered the German opposition. German CDU leader Mertz questioned in an interview with "German Editorial Network" on the 4th: "No one in our parliament and the German public knows the contents of this visit." He accused Scholz of keeping his Washington trip secret, which was "unconventional".

　　The New York Times said that there is growing opposition in the United States and Germany to aid Ukraine, and Scholz and Biden are also facing the upcoming general election (German parliamentary elections will be held in 2025). Jens, a senior researcher at the German Marshall Foundation, said that in terms of the long-term sustainability of political support, both of them face great resistance. For domestic political purposes, they need each other.

　　German-American relations are frequently questioned.

　　Although Biden called virtue "in step with all aspects", many analysts believe that there are many practical contradictions between virtues on many issues. CNN said that in the two countries, the voice against providing military assistance to Kiev is becoming louder and louder. Therefore, although the two sides announced that they would provide main battle tanks to Ukraine, they still shirked the relevant details. Not long ago, Sullivan, Assistant to the President of the United States for National Security Affairs, claimed that the United States agreed to deliver M1 main battle tanks to Ukraine under the "hard pressure" of Germany. The American statement angered Germany. The german government immediately refuted the us statement. At the Munich security conference not long ago, German Defense Minister pistorius complained without name that "some countries prefer to hide behind Germany" when it comes to tank aid.

　　The explosion of the Russian-European "Beixi" natural gas pipeline in September last year is another point of disagreement between the United States and Germany. Before Scholz’s visit to the United States, a number of German lawmakers demanded that Scholz should take tough words against the United States when meeting Biden. However, judging from the public information, the talks did not mention the "Beixi" incident. "Russia Today" TV station said that the German government remained silent half a year after the incident. "The vassal position of the United States does not allow Berlin to talk about who is behind the scenes, and Germany’s foreign policy is completely locked in the track of Washington", which will make "Germany’s future into a dead end".

　　In addition, Biden signed the "Inflation Reduction Act" last year, and its protectionist provisions dealt a serious blow to the automobile industry in Germany and other European countries. Agence France-Presse said that Germany-US relations are relatively close (closer than France-US relations) because of its heavy dependence on NATO and US military protection. But in fact, relations between the two countries have fluctuated recently. For example, the US Inflation Reduction Act heavily subsidized the green industry, which triggered a strong rebound in Germany, but was ignored by Washington.

　　Before the talks, White House officials said that the China issue was also one of the topics of the talks. However, during this visit, Scholz avoided the topic of China. "Deutsche Welle" said that Germany is still waiting to see that China is Germany’s most important trading partner, and the idea of losing business in China will "cause German manufacturers to worry about their survival".

　　"Big Brother is back."

　　Tsargrad TV station in Russia said that at present, the political and military prestige of the West is in jeopardy, and the Western people are increasingly dissatisfied with the government’s practice of arching fire. Due to lack of confidence in France, Britain’s economic situation is difficult and it is no longer a member of the European Union. The United States hopes that Germany will play a key role in mobilizing the European Union against Russia and China. According to the report, judging from the brief press release issued by the two sides after the talks, Scholz showed its "loyalty to Washington as a vassal country. Americans know how to treat weak politicians and obedient countries. "

　　"Big Brother is back", the cover article of the latest issue of German "Star" magazine reported on this topic. For Scholz, "Fortunately, there is Biden — — We can count on the United States again in the conflicts with Russia and China. ".

　　Volodin, chairman of the Russian State Duma (lower house of parliament), wrote on social media on the same day, according to a report by RIA Novosti on the 5th: "The United States once again shows that its basic policy principle is to use other countries to realize its own interests. The United States forced European countries to support the Kiev regime at the expense of their citizens’ welfare, but their own expenses were much less than those of other countries. " He said that the United States spent only 0.37% of its GDP on supporting Ukraine, while Poland spent 2.1% of its GDP. In addition, EU countries have paid an extra price for anti-Russian sanctions, which has affected the national economy. The loss of energy in European countries is about 570 billion euros, and the loss in Germany accounts for 7.2% of GDP.

　　In recent years, "big data" has gradually moved from academic concept to industrial application, and has become the "window" for the Internet industry to compete for each other. However, although there are endless ideas, research and plans about big data in the industry, most companies have not actually enjoyed the change dividend brought by big data.

　　Nowadays, with the maturity of face recognition, artificial intelligence, cloud computing and other technologies, big data applications have also landed and begun to reshape existing business models.

　　Fashion can also be customized.

　　The favorite color of young people born after 1995 in China is "unsaturated black" with RGB value of 22/20/24. When buying clothes, the colors they most often match with black are "red, yellow and blue". The favorite clothing materials are cotton, wool and leather, and the favorite colors are printing, graffiti and letters … …

　　The above conclusions come from the "China Post-90s Fashion Color Report" jointly released by Tencent and e-commerce platform Vipshop. Relying on Tencent’s AI (artificial intelligence) face recognition and image processing technology, based on Tencent’s QQ space 2 trillion social media photos and Vipshop’s 100 million e-commerce users’ sales data, the two companies jointly "calculated" China’s "post-1995" dressing preferences.

　　It is not easy to extract the "fashion factor" from 2 trillion photos and 100 million e-commerce user data. According to Liang Zhu, vice president of Tencent Group and head of Youtu Lab, finding these popular colors needs to overcome many technical difficulties. For example, the photos uploaded by users in QQ space are mainly life photos, and the background and colors are very complicated. In order to achieve accurate color acquisition, its technical team uses many artificial intelligence algorithms, including human body detection and clothes segmentation, to separate the human body and clothes in the photos from the background, and its pixel segmentation accuracy reaches 95%.

　　It is understood that the two companies jointly invited designers to design fashion clothes based on the calculation results, and plan to sell them online on the Vipshop e-commerce platform this fall.

　　"Face recognition and image processing technology based on machine learning has always been a hot technology in the future, and its application range is very wide. At present, Tencent Youtu’s AI image recognition technology is very mature and can be applied in different scenarios. " Beam-column representation.

　　No longer "looking at the number and sighing"

　　In the past, big data applications were mostly confined to the marketing level. Its essence was to use the advantages of "big data" to analyze market factors such as user behavior by traditional computing methods, which was not a real big data application. In the face of massive and precious data, it is often impossible to really use it, and it can only be "sighing and sighing".

　　Nowadays, the application of big data has broken through the limitations of data capture and statistical methods in the past, and has begun to penetrate into all aspects of the industrial chain, becoming a "closed-loop ecology" that runs through big data.

　　In the retail field, following the concept of "new retail" put forward by Alibaba last year, at the beginning of the new year, Alibaba Group signed a comprehensive strategic cooperation agreement with Bailian Group, announcing the joint efforts to explore and develop a new retail model. According to Ali, based on big data and Internet technology, the two sides will cooperate in six areas: all-format integration and innovation, new retail technology research and development, supply chain integration, member system interoperability, payment financial interconnection and logistics system coordination.

　　"The new retail is to use the Internet and big data to ‘ People, goods and fields ’ And other traditional business elements, including the reconstruction of production processes, the reconstruction of the relationship between merchants and consumers, and the reconstruction of consumer experience. In the future, business will no longer be divided into online and offline, and there will be no difference between virtual entities. " Zhang Yong, CEO of Alibaba Group said.

　　In the field of household appliances, according to the newly released White Paper on Smart Air Conditioning Market in China in 2016, the domestic smart air conditioning industry has been improved in manufacturing, channels, services, resources and application level of new technologies in 2016, especially the introduction and resource sharing of cloud and big data technology, which has laid a solid foundation for resource sharing and service innovation in related industries.

　　Take Haier, a home appliance company, as an example. Relying on big data, the air conditioners produced by Haier not only built an intelligent energy-saving system, but also applied big data to the fields of heating and power supply. In Jiangsu, Haier’s air-conditioning cloud data has been effectively connected with the State Grid, so as to adjust the peak power load of residents, reduce the peak-valley difference of the grid by 18.47%, and greatly ease the operating pressure of the grid.

　　Realize "personalized mass production"

　　In fact, the continuous application of big data is solving the contradiction between "personalization" and "mass production" in the past, which has brought about changes in business models.

　　In the past, mass-produced products could hardly meet the individual needs of customers. Even with massive data as the marketing basis, we could only subdivide the needs of users as much as possible, and then mass-produce in each subdivision. With the penetration of Internet, big data, cloud planning and other technologies, it is possible to meet personalized and customized needs, and personalized mass production is being tried and explored. According to Chen Feifei, senior director of Vipshop, it is a bold cross-border innovation to apply big data to the fashion industry and conduct e-commerce operation. "Let photo big data, sales big data, artificial intelligence collide with fashion trends, connect data with art, and provide more inspiration and possibilities for creation in the fashion field." Chen Feifei said.

　　This attempt has brought obvious changes to the production mode of fashion industry, that is, from the former designer-led mode to the user-centered personalized mass production mode. Consumption data will become the most valuable resource in the fashion industry ecological chain. Whoever has more accurate user data will have more market opportunities.

　　Similarly, in the field of household appliances, Haier air conditioning can simulate 30 body parts, 20 metabolic modes, 162 neuron sensors and 17 warm and cold environments through joint research and development of intelligent bionic human technology. At the same time, relying on bionic people, we have developed original technologies and products such as natural wind, self-cleaning and ion air supply to realize personalized energy saving for thousands of people and make every air conditioner produced in batches "different".

　　In the field of medical and health care, because of the different disease history and genetic composition of each person, the standardized treatment scheme for diseases in the past is more like a "stopgap measure" under technical restrictions. Nowadays, with the breakthrough of medical sensors, monitors and diagnostic technologies, patient data has become complete and detailed. On this basis, the artificial intelligence system can comb the medical records, genome sequences and other health behavior data of millions of patients, so as to match the personalized treatment plan.

　　Various trends show that this change in business model is rapidly infiltrating into various industries. The universal landing of "personalized mass production" will also be possible with the support of big data.
