Cctv news: At the opening ceremony of 2018 China International Big Data Industry Expo, the General Secretary of the Supreme Leader personally sent a congratulatory letter. The congratulatory letter clearly pointed out: "Focusing on building a network power, a digital China and a smart society, fully implementing the national big data strategy will help China’s economy shift from high-speed growth to high-quality development." The General Secretary profoundly analyzed the current situation and trend of big data development, put forward clear requirements for implementing the national big data strategy and accelerating the construction of digital China in light of China’s actual situation, actively pointed out the direction for the strategy of making good use of big data and winning the development of the new era, and marked that the Digital Expo and Guizhou’s big data development career stood at a new starting point and entered a new journey.

　　Big data drives high-quality development

　　Data is the new oil and the most precious property in this century. "whoever has the data will have the initiative." As the first national-level big data comprehensive experimental zone in China, from 2013 to 2018, Guizhou has won the status of a pioneer with innovation among the provinces in the country, from scratch, to take root, and then to the wind and water. Guiyang, a "provincial capital city with no sense of existence", has achieved phoenix nirvana with big data in a few years, making the world sit up and take notice. In 2017, Guiyang proposed to build a "China Valley" to create an upgraded version of big data development. In 2018, Guiyang issued an implementation opinion, taking the development of digital economy as a new engine to accelerate the conversion of old and new kinetic energy and promote high-quality development. The butterfly change in just a few years has become a huge gravitational field. Here, the epitome of "Digital China" is converging.

　　"Everything can be digitized", which promotes quality change and creates unlimited opportunities for integrated development. In recent years, Guiyang has taken the information infrastructure construction as the support, the promotion of data convergence as the basis, the Internet and big data as the focus, the informationization and digital transformation as the core, and the "introduction of thousands of enterprises" and "transformation of thousands of enterprises" as an important starting point to accelerate the transformation and upgrading of traditional enterprises.

　　By the end of 2018, Guiyang had implemented 589 integration projects with a total investment of 38.08 billion yuan, launched 36 provincial-level benchmarking projects and 300 municipal-level integration demonstration projects, and organized the evaluation of the integration degree of 3,569 enterprises. Guiyang has promoted the integration of big data and the real economy, and the transformation of old and new kinetic energy has continued to accelerate, which has promoted the integration and upgrading of tourism, commerce, logistics, finance, transportation and other industries in the city to a platform-based, intelligent and shared type.

　　Big data improves quality and efficiency to achieve dynamic change.

　　Big data is like a catalyst. Wherever it goes, it will cause amazing changes and efficiency changes. As the main battlefield for poverty alleviation in the country, Guiyang has promoted agricultural quality improvement and efficiency improvement through big data information technology, deepened the rural industrial revolution through "big data+agriculture", and made big data run through all aspects of agricultural planting, transportation and sales, improving the digitalization, precision and intelligence of agricultural production. At present, China is in a critical period of the conversion of old and new kinetic energy. Big data is an important means to promote the conversion of old and new development kinetic energy. Through deep integration with traditional industries, big data runs through all aspects of production, circulation, sales and service of traditional industries, in order to achieve high-quality development. Inject new kinetic energy.

　　Practice the "people-centered" development concept, make good use of big data to benefit the people and solve their worries, so that the people can have more "gain" from the development of big data, and then promote dynamic change. With the help of big data, such visions and actions are gradually turning into concrete and sensible convenience scenes by promoting the "convergence of big data and government services" and "doing everything in one door and doing things in the whole province in one network".

　　In multi-dimensional application scenarios, people are no strangers to big data, but efforts to break down barriers are still indispensable to fully tap the powerful driving force of big data. Guiyang is vigorously implementing high-level opening-up and accelerating high-quality economic development. Only by realizing the "convergence" of big data in concept cognition and system design, and stirring a pool of spring water with the "fusion" and "use" of big data, can big data truly become a starting point for practicing new development concepts and promoting high-quality development.

　　Big Data Leads Industry Digitalization

　　General Secretary of the Supreme Leader pointed out in the report of the 19th National Congress of the Communist Party of China that "promoting the deep integration of Internet, big data, artificial intelligence and real economy" is a major strategic choice made by the CPC Central Committee based on the overall situation and facing the future, which is of great significance and provides us with fundamental follow-up.

　　Guizhou is the first national big data comprehensive experimental zone, and it has also been awarded the "golden signboard" of Guiyang National Big Data Industry Cluster and Big Data Technology Innovation Experimental Zone. Guizhou Province undertakes the heavy responsibility of exploring the national big data strategy, and Guiyang also shoulders the responsibility of creating big data development concepts, systems and initiatives. From 2014 to the present, this city located in the southwest has overcome difficulties and held high the banner of big data development, catching up and leaping forward all the way, singing the strong voice of big data development, and completed the gorgeous turn from "the old and the young are poor" in the western mountain city to "China is counting the valleys". This low-key western capital city has now been full of vitality.

　　Guiyang regards the deep integration of big data and real economy as the main direction of big data development, vigorously promotes the application of big data technology in various scenarios, leads three industrial transformations and upgrades with big data, improves the quality and level of supply system, and promotes the real economy to move towards high-end, intensive and green. According to the overall report on the development of big data in Guiyang in 2018, the main business income of big data enterprises in Guiyang reached 100 billion yuan in 2018, an increase of 22.4%; The revenue of full-caliber software and information technology service industry was 28 billion yuan, up by 23.5%, of which 5 million caliber was 14 billion yuan, up by 27.3%; Software service outsourcing and call center industry realized business income of 5.02 billion yuan. 51 new big data enterprises were added, with a total of 208; 82 new big data industry projects were signed, with a total investment of 19.496 billion yuan.

　　In recent years, the construction of Guizhou National Big Data Comprehensive Experimental Zone has been deepened, the integration of big data and real economy has been accelerated, the opening of government data sharing has been accelerated, and the construction of new formats and new models of big data has been accelerated. The development of big data in Guizhou has entered a new stage and stepped onto a new level. Statistics show that 2016— In 2018, the integration index of industrialization and informatization in Guizhou rose by six places in the national ranking, and the first index evaluation system for the deep integration of big data and real economy in China was established. In 2018, the GDP of Guiyang increased by 9.9%, and the economic growth rate ranked first in the provincial capital cities for many years.

　　Good wind, with its strength, sent me to Qingyun. From the aspects of big data policy, platform, capital, technology, talents, brand, industrial upgrading, state support, application creation, practice and project operation, today’s "experimental field" in Guiyang, Guizhou has gradually changed from "nothing" to ∞ " , has taken shape. Under the guidance of the spirit of the important instructions of the Supreme Leader General Secretary and the spirit of congratulatory letter, keeping the two bottom lines of development and ecology and making good use of the number fair, an important platform for opening to the outside world, will definitely promote Guizhou’s big data to ride the "cloud" and promote high-quality development to a new level.

　　[car home Technology] Today’s technology may still be far from us, but it is precisely because of its announcement of mass production that I personally think it has epoch-making significance in some technical details. So what is the core of today’s talk? To sum up in one sentence: Who gave "Feng Tu" (founder of Koenigsegg: Christian von Koenigsegg) the courage to sell a three-cylinder hybrid car for more than one million euros?

○ 30s Understand technical points.

　　1. This is a four-wheel drive hybrid car that can be "directly driven".

　　2. It is "1000 horsepower" and "100 horsepower" for 1.9s, and it has four seats.

　　3. It is inextricably linked with Evergrande and Qoros.

　　4. It has no gearbox and the engine has no camshaft.

　　5. It has only three cylinders, but it has two turbines.

　　6. It sells for 1.38 million euros.

○ Let’s take a look at how it is realized.

　　The acceleration level of 0-100km/h is less than 2s. What impressed me last time was Tesla Roadster, a pure electric sports car that has not yet been put into production, and that car also claims to have a torque of 10,000 Nm. It can be said that it has earned enough attention and is full of gimmicks. Regarding the concept of torque on wheels, don’t think it’s great to "break thousands" on wheels, but anyone who knows the concepts of "transmission ratio" and "deceleration and torque increase" should know what I’m talking about. )

　　Let’s not worry about whether the actual test results can be achieved so fast, even if we take "entering 2s" as the target result, it will be difficult to land. This is not a simple matter of "brushing a computer from 7s to 5s". The difficulty of shortening the time from 3s to 2s at 0-100km/h is not something that can be solved by "increasing horsepower without brains" at all. It involves many factors such as tire grip, starting torque control, aerodynamics, body and suspension strength, and it takes great energy and huge sums of money to complete every acceleration shortened by 0.1s.

　　However, it is not easy to achieve this acceleration in a four-seater car. For this reason, Koenigsegg has already prepared: using the hybrid system on Koenigsegg Regera, let the motor and gasoline engine push this big guy together. Adding a motor seems to be a good solution, but as long as you know a little about the founder, you know that this "Viking madman" will definitely not use these "traditional" solutions on Toyota Prius or McLaren P1, but adopt a magical solution called KDD(Koenigsegg Direct Drive) system (want to know more about Koenigsegg Regera and KDD technology? Click me for more details)

　　This idea is really crazy, relying on a fixed transmission ratio to achieve horrible acceleration. This idea is quite popular in the linear acceleration race of Top Fuel in North America (although it is not a single fixed gear ratio, there are only two or three gears to ensure acceleration). But if you think Koenigsegg (|) is just "changing the shell" Regera, then I can only say that you are too Naive.

　　In this way, Koenigsegg Gemera can realize four-wheel drive, the front axle is driven by KDD system, and the rear axle is driven by two P4 motors. Under different working conditions, theoretically, it can realize three driving modes: front drive, rear drive (pure electric state only) and four-wheel drive. From a certain point of view, this is an evolution based on Regera, but I still don’t understand why the middle and rear engine scheme is used …… "Cloud guess" may be due to ensuring that the front axle and half axle are equal in length and geometry, so that torque steering will not occur when starting, and balancing the counterweight.

○ Koenigsegg, you big eyebrows and big eyes actually use a three-cylinder machine!

　　Don’t worry about it! At the beginning, I once planned to talk about Koenigsegg’s rather confusing practice, but I was lost in thought until I found that "FreeValve" was written on this engine.

　　This may be the first camshaft-free engine in the world! I’m asking you if you’re satisfied with this alone? "Viking madman" lives up to its reputation. But don’t rush to brag about this technology, because I will tell you a fact that you will feel particularly proud: this technology has a very close relationship with a China brand-Qoros.

　　In fact, for camshaft-less technology, I believe many big car companies have technical reserves, but it depends on the story of Koenigsegg and Qoros. To put it simply, Koenigsegg and Saab jointly invested in a company called Cargine Engineering in 2000, and started to optimize the valve timing adjustment technology. In 2003, the first Saab 9-5 equipped with camshaft-free technology began road test; In 2009, Koenigsegg acquired Cargine Engineering and renamed it FreeValve. On the Qoros side, it is because when Chery independently developed the engine, it cooperated deeply with a famous engine development company, AVL Liszt, and AVL Liszt is the most important partner of FreeValve. As a result, Qoros and Koenigsegg "worked together" and installed the camshaft-free engine on Qoros 3 for testing. (For details, click the following link: the story of Qoros and Koenigsegg/the first trial of Qoros camshaft-less engine)

　　With this "dream" scheme, it is easy for the engine to get high power, high thermal efficiency and low fuel consumption in theory, which can definitely be regarded as one of the most revolutionary technology decentralization in recent years, so that the internal combustion engine can "fight for another half century"!

　　Of course, this system also has some problems: reliability and working logic. The former believes that a good result has been obtained after years of testing, otherwise Koenigsegg will not rush to load the car, while the latter will make the engine calibration engineer have a headache, and the realization of ideal parameters needs to take into account many problems. The traditional camshaft structure has a very mature scheme. Without the camshaft, the valve control and adjustment work will become very complicated, but any mistake will have incalculable consequences.

　　In addition, there is a relatively unpopular concern: a three-cylinder engine with dual turbochargers. This may sound like nothing, but it seems that there are few such schemes for odd cylinders with twin turbines. The simple reason is how to balance the intake and exhaust stability of odd cylinders with two turbines. Even cylinders can be evenly distributed. What should be done with odd cylinders?

　　To sum up, this engine has many points of view in valve structure and supercharging design, and even can be regarded as two new outlets for small displacement engines in the future. Together with the cooperation scheme of KDD system and motor, everything looks very powerful except the powertrain engineer. Of course, the price of more than one million euros is also scary. You have everything in your dreams. Go to bed early.

Editor’s summary:

　　This is not just a three-cylinder hybrid car. In my opinion, its technical route seems to have opened up a new idea for many car companies: hybrid oil and electricity can save the transmission mechanism, even if the speed regulating motor can be integrated into one to complete the work; In the part of internal combustion engine, the camshaft-free design and the three-cylinder twin-turbine scheme also have a lot to talk about. These not only realize new ideas for high-performance cars in the future, but also have great significance for internal combustion engines and hybrid technologies. Again, it’s not that I don’t agree with pure electric vehicles, but the potential for internal combustion engines and hybrids to be developed is too great. (Text/Figure car home Shu Ning)
