It’s a medium-sized model. I wonder how much you know about it. Let’s take a look at its performance.

First of all, from the appearance, the shape of the head of Haval’s second-generation big dog looks very round and sporty. Headlights are concise, and many interesting details can be seen from them. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Come to the car side, the car body size is 4705MM*1908MM*1780MM, the car uses simple lines, the car body looks very simple, with large-sized thick-walled tires, it looks full of sports. In the design of the rear end, the overall shape of the rear end of Haval’s second-generation big dog echoes the front end, the taillights are very round, and the unique exhaust pipe creates a good gas field.

Sitting in the car, the interior looks very fashionable and simple, and the overall design is very cold. The steering wheel of this car is very comfortable, and it is equipped with the functions of manual steering wheel up and down+front and rear adjustment, steering wheel heating, etc., which gives people a bright feeling. Let’s take a look at the central control. The car is equipped with a touch-sensitive LCD central control screen, which makes the interior design quite layered and looks sporty. Let Xiaobian introduce the dashboard and seats. The car is equipped with a cool dashboard, which is very eye-catching. The car adopts imitation leather seats, which are wide and thick and comfortable.

Haval second-generation big dog is matched with wet dual clutch (DCT) gearbox, with maximum power of 175KW and maximum torque of 385N.m, with good power performance.

Next, look at the configuration. The Haval second-generation big dog is equipped with car networking, driving mode selection, remote control key, Bluetooth key, rear wiper, engine start and stop and other configurations.

OK！ Next, let’s sum up. The model class introduced today is the most considered class when many people buy their first car, mainly because the size of this class is moderate and the price is reasonable.

　　After the development of carburetor, single-point EFI, multi-point EFI and multi-point sequential EFI, many luxury car manufacturers have made progress in the field of direct injection.

　　The direct injection engine is different from the ordinary engine in the fuel injection mode. The fuel is injected into the cylinder directly instead of being mixed with air in the intake manifold. With the accurate calculation of the ECU control unit of the engine, this combustion mode can control the fuel injection amount according to the working conditions of the engine, and the performance, fuel consumption and emissions of the engine can be optimized accordingly.

　　The earliest direct injection system was invented by Bosch Company in 1950s, and was first applied to Mercedes-Benz SL300 in 1955. However, it was gradually forgotten because there was no mainstream development trend at that time. It was not until 1996 that the direct injection gasoline engine reappeared in the market. Mitsubishi Corporation of Japan introduced their GDI direct injection technology into Galant’s 4G93 engine and sold it in the Japanese market. Subsequently, Mitsubishi Carisma equipped with this technology also entered the European market, and today’s "direct injection fever" developed from this.

　　Facing the problems of energy and environment and the development of engines, Volkswagen, Mercedes-Benz, BMW and Cadillac have invested a lot of manpower and material resources to explore new technical fields. In the domestic market, Volkswagen and Audi’s FSI technology has become a star product in this category, but with the arrival of Cadillac’s new CTS, BMW X6xDrive50i and other models, Volkswagen FSI engines have ushered in more competitors. At present, the mainstream models with direct injection technology in the domestic market are only some high-end models, but we have reason to believe that with the development of technology, this technology beneficial to you, me, energy and the environment will be gradually popularized.

New CTS and its SIDI direct injection engine

　　Universal SIDI

　　SIDI all-aluminum dual-mode intelligent direct injection engine adopts universal third-generation direct injection technology. Among them, dual mode refers to homogeneous combustion and stratified combustion. SIDI engine can automatically adopt stratified lean combustion mode when the throttle is half open and automatically enter homogeneous combustion mode when the throttle is full. The automatic conversion of these two modes will directly improve the effective utilization rate of fuel. The method used by general SIDI to realize layering is also different from the eddy current method of Volkswagen, and the controllable oiling process is the key step to realize layering oiling.

　　Representative model: Cadillac CTS3.6L flagship high-performance version

　　Cadillac CTS3.6L flagship high-performance version is equipped with this 3.6LSIDI engine. Compared with the previous generation CTS3.6L engine, the maximum power and torque of this SIDI engine have increased by 15% and 8%, reaching 229kW and 374N·m respectively. Due to the introduction of direct injection technology, the fuel consumption of this engine is also reduced by 3% compared with the previous generation engine, and the hydrocarbon emission is also reduced by 25% during cold start.

　　Volkswagen FSI

Volkswagen FSI has a high reputation in China.

The nozzle of FSI is below the intake pipe, and the nozzle placement of each pair is different.

　　Volkswagen was one of the first manufacturers to introduce direct injection technology into China. Nowadays, FSI (Fuel Ratio Injection) has become a familiar word for consumers. FSI refers to stratified fuel injection, which is a direct injection technology for gasoline engines. At the beginning of FSI, this technology had stratified lean combustion, but it was later cancelled for various reasons, and only the direct injection technology was retained. Audi used vortex effect to realize stratified lean combustion before. Although this technology was cancelled, the remaining direct injection technology also performed well in terms of power and fuel economy. Compared with the traditional engine that directly injects fuel into the intake manifold, the FSI fuel direct injection engine can significantly improve the power, make the output torque and power higher, and reduce the fuel consumption rate by 15%.

　　Representative model: Audi A6L3.2FSI

Audi A6L 3.2 has not only quattro four-wheel drive technology, but also FSI.

　　At present, compared with the previous 3.0LV6 engine, the 3.2LFSIV6 engine equipped on the Audi A6 model has a maximum power of 26kW and a maximum torque of 30N·m and 330N·m, and the fuel efficiency has also been significantly improved. It is a highlight of FSI technology to combine engine power and fuel economy well.

　　Bmw HPI

From this picture, we can clearly see the direct injection technology structure of BMW.

　　Many people don’t know about BMW’s high-precision injection system, HighPrecisionInjection. In fact, it is an integral part of BMW’s EfficientDynamics system and an important part of BMW’s improvement in power and fuel economy. The precise piezoelectric nozzle located between the intake valve and the spark plug can provide a pressure of up to 200Bar to fully atomize gasoline and complete the process of injecting it into the combustion chamber in 0.14 milliseconds, so that the fuel economy pursued by engineers is completely guaranteed. BMW does not add stratified combustion technology to this system, but achieves the purpose of improving fuel consumption rate through fuel atomization.

　　Representative model: BMW X6xDrive50i

BMW X6 xDrive 35i has entered China, and X6 xDrive 50i will meet domestic consumers soon.

　　The X6xDrive50i, which is about to enter the domestic market, is equipped with this direct injection system, and its power performance is also very remarkable because of its dual turbocharging system. Its maximum power is 300kW, its maximum torque is 600N·m, and its comprehensive fuel consumption is 12.5L/100km (it is worth noting that this is the data of a 4.4LV8 twin-turbo engine).

　　Mercedes CGI

The highlight of Mercedes-Benz CGI lies in its high-pressure piezoelectric nozzle technology.

　　Compared with Volkswagen and BMW, Mercedes-Benz’s publicity in this respect is somewhat low-key, but this does not mean that this German company is inferior to its competitors in this respect. Mercedes-Benz has been committed to the research on vehicle power and fuel economy, and CGI (Hierarchical-Charged Line Injection) is their research achievement. In 2006, Mercedes-Benz launched the 350CGI engine, which was the first time to apply the piezoelectric nozzle to the direct injection technology of gasoline engines. Compared with the popular mode of using vortex to produce stratified effect, Mercedes-Benz solves this problem well by using high-pressure piezoelectric nozzle, and forms the required stratified combustion mode by using the spray generated by high pressure. It is also for this reason that this engine effectively reduces fuel consumption by as much as 10% compared with the previous engine.

　　Representative model: Mercedes-Benz CLS350CGI

At present, it seems that Mercedes-Benz CLS 350 CGI has little fate with domestic consumers.

　　The maximum power of ordinary Mercedes-Benz CLS350 is only 200kW, the maximum torque is 350N·m, and the fuel consumption per 100 kilometers is 10.1L. Mercedes-Benz CLS350CGI has reached the maximum power of 215kW and the maximum torque of 365N·m, and the fuel consumption per 100 kilometers is 9.1L That is to say, after adding CGI technology, the maximum power, maximum torque and fuel consumption rate of the engine have improved by 7.5%, 4.3% and 10% respectively. Therefore, it can be seen that Mercedes-Benz is not inferior in this respect. After the successful appearance of CLS350CGI in 2006, Mercedes-Benz applied this engine to E-CLASS, S-CLASS and other models, but these models have not yet met with domestic consumers.

Fast Technology April 15th news, ask the world M5 series Huawei high-end intelligent driving version will be released on April 17th, travel comfortable, peace of mind, more worry-free!

It is understood that the car’s greatest highlight is the use of Huawei’s latest ADS high-level intelligent driving system, which can achieve high-level assisted driving without relying on high-precision maps.

Today, the urban measurement video of the M5 smart driving version of the Q Jie was exposed online. In the case of unmanned operation,The M5 Smart Driving Edition is very slippery at intersections, tunnels, elevated roads, night roads, and other scenes, comparable to old drivers.

As you can see in the video, with the blessing of lidar + visual perception,The M5 Smart Driving Edition not only successfully realizes unprotected left turns, automatically recognizes obstacles/construction areas and detours, but also avoids significant lane changes or sudden acceleration/braking throughout the process.

The M5 Smart Driving Edition can also enter the left-turn waiting area and recognize the countdown of traffic lights, while safely crossing the opposite lane and performing high-level operations such as comity for pedestrians in zebra crossings and non-motorized vehicles in bicycle lanes.

Sheep heard that Liu Yifei, a fairy elder sister who hasn’t appeared for a long time, recently went down to earth to fight fish as a female anchor? !

Not only Liu Yifei, but also actresses from Tong Liya, Fan Bingbing, Tang Yan and Yang Mi. Is it against the sky to fight fish?

The sheep was shocked at first, and then found that something was wrong. Do you think that these pictures of Sister Tianxian have become like a net red, without her original recognition?

Do you still remember the "Athena Chu’s Yang Mi" which was popular all over the network a while ago?

At first glance, I was shocked to see this group of moving sheep. Yang Mi once played such a smart and delicate Huang Rong? How come I’ve never seen this play released? It must be more popular than to the sky kingdom.

But in fact, this is just an image synthesized by bilibili UP using AI technology, which replaces Athena Chu’s five senses in The Legend of the Condor Heroes with Yang Mi’s.

Because the effect is so realistic, it caused a sensation on the Internet, and the topic has reached more than 100 million readings in Weibo. Then there was."Athena Chu becomes Yang Mi, with a flow of 100 million."The statement.

So later, there was the Yang Mi version of Zhao Min. Is this effect enough to confuse the real with the fake?

There are nine points in the expression of looking up, eyes hanging down and eyes flowing. Can you tell who is who if you don’t take a close look at the five senses?

Not only is the face close-up, but even this video with great dance movements can accurately capture the face and put on the five senses, and it looks like Yang Mi himself jumped.

Seeing this, I don’t think you have to say that you all understand. At the beginning of the article, the female stars who are fighting fish as female anchors are all synthesized by using AI technology.

The female anchor’s real body is a new betta fish sister, Leng.

Before, in order to gather popularity, A Leng had disappeared for a month, and it was suspected that he had double eyelids.

However, compared with AI face-changing female stars, the popularity is only a few hundred Ti mo Feng.

This seemingly fate-changing technology actually does not require much superb code skills, nor does it have to be done by top programmers with bright brains.

AI face-changing technology originated from deepfake abroad, which has been popular abroad for one year, and has also caused heated discussion in Reddit forum, and has just been introduced to China recently.

In January last year, someone directly launched the Windows program FakeApp. You don’t even need to make a model of deepfake. You only need an Nvidia GPU personal computer, 3~4GB of storage space, and even AI knowledge. You can make the face-changing video above.

In fact, we have seen the predecessor of this technology for a long time and have used it in various American special effects blockbusters.

In that year’s "Speed and furious 7", after Paul Walker’s accidental death, his shots were originally replaced by two younger brothers, and the dynamic capture and CGI animation were used to bring him back to the film, giving the audience a happy ending.

With the gradual maturity of technology, face replacement is nothing new.

Just two days ago, the first female host of AI synthesis had been on duty to broadcast, except that her voice was a bit like mechanical words jumping out, and there was not much difference between her face and real people.

AI anchors can work on all kinds of platforms 24 hours a day without gaps, which can reduce news production costs and improve production efficiency for the news industry.

For digital special effects companies, it can save the production cost of later special effects.

For Doubi, sand sculpture and idolize youth, this is the PS in motion.

You can change your face and play opposite your idol.

The experience is similar to the skin in the game we play or the real-life version of ZEPETO.

But at the same time, when this technology was invented, it also brought disadvantages.

In fact, technology itself is not good or bad, but people who use it do. Because the threshold of AI face-changing technology is lowered and the effect is realistic, it has been targeted by many people who have misgivings.

The first to suffer is the foreign actresses, whose "faces" have appeared in the indescribable videos on famous websites.

Wonder woman gerga, Emma Watson and Ai Liya Stark in Game of Thrones were not spared.

Japanese actresses are even more inevitable. (ps: Who put the sheep’s wife P up and stood up to die! ! ! )

Not surprisingly, Chinese actresses have also been recruited! According to incomplete statistics, there are about 30 actresses who have been recruited.

?

I heard that there has been news that "ex-boyfriend put his face AI in the actress’s film", and some people even took the synthetic film for personal blackmail.

Here, I want to say that this is a serious illegal act, which seriously infringes on the right of portrait and reputation.

If the technology is abused by criminals after it is mature, such as stealing brush, fraud, etc., then there will be risks in the application of face brushing technology in our daily life.

At present, Fake is so controversial that it has shut down its website. Websites such as Twitter and PornHub also prohibit uploading such face-changing content.

Bilibili UP owner has also removed the video of Athena Chu changing to Yang Mi, and apologized to Yang Mi, saying that the original intention was not malicious, but just to share new technologies. Also, please treat the technology correctly, focus on the technology itself, and respect the right of portrait and copyright.

Again, technology itself is not right or wrong, and the development of the times can’t stop it from appearing. What we can really do is how to manage the use of standardized technology, and moral law is the bottom line that must be observed!

In fact, no matter how intelligent the machine is, it is also invented by human beings. On the matter of changing faces, no one can compete with nature. If you don’t believe me, look at those amateurs who are not related to the face-bumping stars. They are not only similar in shape but also similar in spirit. That is really the highest realm of face-bumping, hahaha!

Therefore, the sheep are curious. How much can everyone look like a star without relying on acquired technology and only relying on innate genes?

　　CCTV News:On the occasion of the 31st World No Tobacco Day, supported by the Propaganda Department of the National Health and Wellness Commission and the Department of Sports Health and Art Education of the Ministry of Education, the Centers for Disease Control and Prevention of chinese association on tobacco control and Beijing held a youth tobacco control activity in Beijing No.11 School with the theme of "No smoking, I am healthy and fashionable". It is understood that more than half of daily smokers in China started smoking before the age of 20. Organize youth tobacco control activities, form a youth tobacco control volunteer alliance, mobilize more young people to take action, and encourage them to take social responsibility for tobacco control in addition to not smoking themselves.

　　This year’s World No Tobacco Day focuses on "tobacco and heart disease", highlighting the relationship between the use of tobacco products and heart injury and cardiovascular diseases, and raising public awareness of the impact of tobacco use and second-hand smoke exposure on cardiovascular health. Every year, 18 million people die from cardiovascular diseases, and more than 2 million of them die from tobacco use. Smoking and secondhand smoke exposure are sometimes the main factors causing diseases. For example, 69 carcinogens are known to directly cause cancer, and there is sufficient evidence that smoking can cause lung cancer, oral and nasopharyngeal malignant tumors, laryngeal cancer, esophageal cancer, gastric cancer, liver cancer, renal cancer, bladder cancer and cervical cancer.

　　Since the entry into force of the WHO Framework Convention on Tobacco Control in China, China has made positive progress in tobacco control implementation. Eighteen cities across the country have promulgated local laws and regulations prohibiting smoking in public places, especially in Beijing, Shenzhen and Shanghai. Li Nong, deputy director of the Propaganda Department of the National Health and Wellness Commission, pointed out that China’s tobacco control implementation still faces some challenges, and the adult smoking rate is still at a high level. The survey shows that the smoking rate of teenagers in China is 6.9%, the rate of trying to smoke is 19.9%, and 180 million children suffer from the harm of second-hand smoke. We must attach great importance to adolescent tobacco control, adhere to the concept of "great health, great health" and the policy of "integrating health into all policies", adhere to the working mode of "government-led, multi-sectoral cooperation and participation of the whole society", make joint efforts of the government, schools, families and the whole society, formulate tobacco control policies, build a supportive environment for tobacco control, strengthen tobacco control health education, and create a social atmosphere conducive to adolescent tobacco control.

　　The Outline of Healthy China 2030 has set the goal of "By 2030, the smoking rate of people over 15 years old will be less than 20%". Liao Wenke, vice president of chinese association on tobacco control, pointed out that in order to achieve this goal, it is necessary to strengthen tobacco control among teenagers. Only by strengthening the education of smoking control among teenagers and stopping them from smoking can we effectively reduce the number of new smokers and achieve the set goals. To strengthen adolescent tobacco control work, we must innovate educational methods and technologies, enrich educational channels and means, and popularize tobacco control knowledge in ways and means that young students can hear, understand and listen to. We should not be satisfied with publicity and education in content and form, but work hard on pertinence and effectiveness to truly implant the knowledge and concept of tobacco harm to health into people’s hearts.

　　Xu Zhen, deputy director of the Department of Sports Health and Art Education of the Ministry of Education, pointed out that the Ministry of Education attaches great importance to tobacco control in schools and actively promotes tobacco control in schools from two aspects: system construction and health education. The theme of this activity is "I am healthy and fashionable if I don’t smoke". I hope that the majority of young students will take non-smoking as "fashion", take the lead in establishing new ideas in lifestyle, including interpersonal communication, take pride in non-smoking and take non-smoking as the high quality of life, and form a model of healthy lifestyle, thus driving more people in the whole society to pursue this new fashion.

　　In China, more than one million people die of diseases caused by tobacco every year. Sun Jiani, an official of the World Health Organization’s representative office in China, believes that the hope of reducing smokers in China is pinned on young people, and the hope of reducing smokers in the world is pinned on China, because smokers in China account for one-third of the world’s total, and tobacco consumption accounts for 44% of the world’s total. Tobacco control in China has not only protected national health and sustainable economic development, but also made great contributions to the world. In order to realize a smoke-free future, I hope volunteers dare to say "no" to tobacco. It is expected that more teenagers will join the tobacco control team and appear on the tobacco control stage in the future, which will add new strength and inject more fresh blood into the tobacco control team in China and even the whole world.

　　Deng Ying, director of Beijing Municipal Center for Disease Control and Prevention, introduced the preparation of the Youth Tobacco Control Volunteer Alliance on behalf of the Youth Tobacco Control Professional Committee. Since 2016, the Youth Tobacco Control Committee has established a youth volunteer team on a pilot basis, and organized tobacco control activities through the volunteer alliance, making students the main body of tobacco control activities, which has received great attention and affirmation from the society. In order to promote the youth tobacco control volunteer alliance to carry out activities on a larger scale, chinese association on tobacco control registered the National Youth Tobacco Control Volunteer Alliance on China Volunteer Service Network this year, calling on all governing units of the volunteer alliance to carry out the national youth tobacco control volunteer activities simultaneously during the World No Tobacco Day, and starting the recruitment activities of the National Youth Tobacco Control Volunteer Alliance before the World No Tobacco Day, calling on more young people to join the National Youth Tobacco Control Volunteer Alliance and participate in the tobacco control activities of tobacco control volunteers.

　　Wu Jing, deputy director of China Health Education Center, talked with you about the harm of tobacco and how to carry out health promotion and education on tobacco control in schools from the perspective of health education professional institutions. He believes that smokers will not only inhale tobacco smoke themselves, but also spread the smoke into the air, forming second-hand smoke. A large amount of research evidence shows that smoking can lead to multiple malignant tumors and other chronic diseases, leading to abnormal reproduction and development. Most young smokers will continue to smoke when they enter adulthood, and it is difficult to quit. The younger they start smoking, the more they smoke in adulthood, and the greater the harm caused by tobacco. Therefore, taking effective measures to prevent teenagers from smoking is the key measure to curb tobacco epidemic and reduce tobacco harm.

　　Wu Fengqin, Vice President of Beijing No.11 School, highly praised the youth volunteer activities for tobacco control. He believed that organizing the youth tobacco control activities through the volunteer alliance not only created a good atmosphere for tobacco control in the school, but also helped to improve the cultural quality and moral cultivation of the majority of young people, and helped them adapt to and integrate into society. The school will actively support and encourage students to join the volunteer team of youth tobacco control, and also hope that students will actively participate in and organize tobacco control activities in line with their own reality, and effectively promote the extensive development of tobacco control activities in schools.

　　Zhou Rundong, a representative of youth tobacco control volunteers, introduced the previous experience of youth tobacco control volunteers’ activities, and told the gains from participating in youth tobacco control volunteers’ activities from the perspective of students, which infected the student representatives who participated in the activities with their true feelings of participating in tobacco control volunteers’ activities. Chinese association on tobacco control hired Tong Jian, the world champion of figure skating, as China’s ambassador for tobacco control, and Vice President Liao Wenke presented him with a letter of appointment. Ambassador Tong Jian made a speech on tobacco control based on his own experience: figure skating is a sport that combines strength and beauty, and both a healthy body and a beautiful posture are necessary for figure skating. Without a healthy body and a strong body, it is impossible to complete difficult training, let alone complete beautiful movements on the field. Smoking not only damages health, but also damages the beauty of human body. I hope that the majority of teenagers will pay attention to their physical and mental health, develop a healthy lifestyle of non-smoking and diligent exercise, stay away from tobacco, resolutely refuse to smoke the first cigarette, and become a new generation of "non-smoking makes me healthy and fashionable".

　　At the end of the meeting, the leaders and guests jointly launched the national recruitment activity of "National Youth Tobacco Control Volunteers Alliance". At the scene, many students went to the information desk to learn about the related issues of registering young tobacco control volunteers, and some students completed the volunteer registration on the spot.
