In cold weather, whether it is necessary to warm up the car has always been a concern of car owners. In some areas, the engine needs to run at high idle speed for a period of time to reach the normal working temperature. Specifically, the fast idle speed of cold car is to let the engine run at a high speed for tens of seconds to about 1 minute, and after the water temperature reaches the temperature set by the driving computer, the idle speed returns to normal. The normal working temperature of the engine is generally 80-90℃, and the calibration of individual engines is about 100℃, but it is not necessary to make the engine reach this temperature in daily hot cars. Generally, the coolant temperature is 60℃ and the engine oil temperature is above 50℃, which can meet the requirements. In addition, the fast idle speed of the cold car is not only for the temperature of the engine, but also for the engine to inject more fuel to preheat and let the three-way catalyst enter the working temperature as soon as possible to reduce automobile emissions. A secondary air pump is also installed in the American standard large-displacement car to preheat the three elements and control emissions during idling. Therefore, it is necessary to warm up the car in winter, but it is not necessary to warm up the car for a long time.

To say that China is the hottest city on the Internet recently, Chongqing must be on the TOP 1 list.

The Title of "8D City" has gone overseas, and the subway can go through the wall, and you can’t tell which floor you are in. The surreal magical cyber night scene has become the "Three tales of mystery in Chongqing" in the eyes of foreign friends.

Let the American little brother dream, let the little sisters in Europe feel excited, Chongqing has been included in the future fantasy list of contemporary young people:

"I was shocked into aphasia, and it felt like time had traveled to 2050."

"I just went there last year and was completely impressed. Being in it is like reaching the future 100 years later. It’s a great city."

"Spider-Man went crazy in Chongqing."

Of course, the sense of Cyberpunk in China city is just one of the topics that have exploded on the Internet. Speaking of playing with Cyberpunk’s sense of the future, we are all used to new energy technology and intelligent driving, and foreign netizens were shocked when they saw it.

Just brush the video of the external network. Under the content of introducing China’s new energy, foreign netizens are basically shocked by "never seeing the world":

"Can you buy it in America? This car looks more upscale than all our cars here."

"The United States will never let such a China car enter the market, and once it rushes into the United States, it will surely kill similar competing products."

"China car, best car."

Even the car navigation can predict that the red light will end in a few seconds, which is a function that everyone in China uses and takes for granted, and it can make them stunned on the spot.

"It’s cool to predict the red light by car navigation! I feel that our country has been left far behind. "

"Can traffic lights be linked with in-car navigation?"

It’s no wonder that the car ideas of foreign netizens still stay in the last century. After all, our country’s sense of existence in the global new energy field has reached the point of "terror".

For ordinary people in China, not only is the proportion of taking taxis to new energy vehicles swishing upward, but the recruitment of new energy enterprises is striding forward in the public opinion field. If you pay attention to the choices of people around you when buying a car, you will find that new energy vehicles, which were once ignored, have now become the first choice of many basin friends.

In their words, it is-"I used to look down on new energy vehicles, but now I am the first to shout".

It is no exaggeration to say that China’s new energy is not just a "rise", but now the general trend is that China’s new energy has gone overseas to "beat up" the world and make up for the lost share in the automobile industry for decades.

How strong is this momentum? Even the traditional car-making powers have a sense of crisis.

Fortune magazine just reported last Sunday that China’s electric vehicles attacked the city overseas, forcing German auto parts manufacturers to change their thinking: "We must adapt to the trend of making cars in China in order to survive."

(Holger Klein, CEO of German auto parts manufacturing giant ZF)

Germans’ worries are not unreasonable. According to the investigation report of Allianz, Germany’s largest financial group, if China’s new energy vehicles continue to develop, by 2030, the total annual net profit loss of European automakers will exceed 7 billion euros (about 54.6 billion yuan).

This figure made them "panic". After all, the sales of European cars are not as good as before, while the sales of local cars in China have been increasing, which has squeezed the living space of European car companies in China.

Now, coupled with the fact that we have finished building cars and exported them to Europe, and rolled them up to Europe at home, we have taken a two-pronged approach, so that comfortable Europeans really feel the cold winter of sales.

(The sales of new energy vehicles in China broke out in the decade from 2011 to 2021, from visualcapitalist)

In addition to the panicked Germans, Japan, another car-making power, could not stand it. Japanese cars also showed signs of "crash" in China, and Japanese experts began to spread anxiety, saying that China had entered a new era ahead of schedule.

According to them, for every four new energy vehicles sold in the world, one of them is from China. In Norway, the number of new cars sold by China New Energy accounts for 79.3% of the total market. Japanese experts sighed greatly: our Japanese car got up early, and now it’s late.

Why did Germany and Japan, a car-making power, suddenly feel a sense of crisis?If we carefully study the export data of new energy vehicles in China, we will find that the brand represented by MAXUS, SAIC Datong, has gradually taught foreign friends over the past few years what is called dimension reduction.

In terms of sales volume, in the wave of China’s new energy export overseas,The cumulative sales volume of SAIC MAXUS in overseas markets in 73 countries and regions has exceeded 300,000 units, and it has become the top stream in developed markets such as Australia, New Zealand, Britain and Norway, accounting for more than 80% of the sales volume.

With the hard power of "All-around Hexagon Warrior", foreign traditional brands of fuel vehicles can no longer stand on the same starting line with us.

From the price point of view, while maintaining the same quality at home and abroad, SAIC Chase MAXUS has successfully played a high premium in overseas markets.

Take TESCO, which has opened stores all over the streets in Britain, as one of the three largest retail enterprises in the world, TESCO has purchased 150 sets of MAXUS pure electric light passenger EV90 refrigerated trucks.

You know, in Britain, the price of new energy products such as pure electric light passenger EV90 has been higher than that of Renault in France, and the sword refers to Mercedes-Benz. Although the domestic price is nearly doubled, SAIC Chase MAXUS still won the order with the strength matching the pricing.

What is even more amazing is that when these cars were delivered, they also created the largest air transport record of electric light commercial vehicles in the world.

TESCO chose air transportation to let SAIC Chase MAXUS send the car to the UK. The freight is more expensive than the goods themselves, which shows how much you want to pick up the car. It is really a two-way trip.

Reliable plus high-end, high premium can also take orders. The more you know about SAIC MAXUS, the more developed countries with long-term cooperation are interested in the brand itself, and the more willing they are to award a wave of industry awards to SAIC MAXUS.

After the British bought it from MAXUS, SAIC Chase, in buy buy, they put the Green Fleet for six consecutive years.(New Energy Vehicle Enterprise Award)The honor of "Electric Vehicle Manufacturer of the Year" was awarded to SAIC Chase MAXUS, and the days when Japanese car companies in Europe, America and Japan once monopolized the awards have become a thing of the past.

Last August, SAIC MAXUS also won one of the most authoritative automobile awards in the world, the "Automobile Innovation Award" in Germany.

This year’s SAIC Chase MAXUS is still like chopping melons and vegetables, and it won the best new energy brand award of the year by autocosmos, the authoritative automobile media in Chile, the "best van 2023" by Businessvan, the preferred strategy website of British container trucks, and the best design model award of Havana Industrial Fair in Cuba in 2023. …

Behind the world’s soft hand in winning prizes, high quality and high premium, it is the cultivation of SAIC Chase MAXUS’s "two blossoms":

On the one hand, it is the hard work of the new energy technology system, on the other hand, it is the foresight of the strategic layout.

Take MIFA 9, the first full-size pure electric luxury intelligent MPV that landed in Europe, as the flagship model facing the global market, positioning the high-end "global hard currency" in environmental protection, technology, comfort and other aspects, which shocked foreign friends with high product strength from the East.

(MIFA 9 unveiled at Birmingham Motor Show, UK)

The early deployment of new energy MPV products has also made MIFA 9 shine in overseas markets and take the lead in stabilizing the high-end.

Now we can see that the results of cultivation have spread all over the world, all over the industry and all fields.

In the logistics industry, SAIC Chase MAXUS won the reputation of "handing the king’s car".SAIC Chase MAXUS light passenger pure electric light passenger EV series stands out among the "picky" car selection standards in developed countries, and postal systems in Ireland, Belgium, Australia and other places have been praised and repurchased.

The logistics team of DPD, the second largest logistics group in Europe, in the UK also heard the news, and signed the largest single order of China brand light passenger car overseas with SAIC Chase MAXUS, which also set a new record for the largest single order of China automobile brand in the UK.

In the chemical industry, T90 EV, a pure electric pickup recognized by the Ministry of Communications of New Zealand at the national level, has also attracted the attention of Chilean lithium mining giant SQM.

Lucky, energy-saving, smart and easy to drive, this car has officially settled in the largest chemical enterprise in Chile.

It can be seen that SAIC Chase MAXUS and other domestic cars have appeared all over the world and in all fields. In the past, I only felt that domestic new energy sources were making progress, but I really didn’t think about the extent of progress. However, judging from the explosive development trend this year and the real data at hand, we have reached this step that can lead the global industry reform.

Once in the era when fuel vehicles occupied an absolute dominant position, our country could not get the core technology, and it was always suppressed by the first superior. Nowadays, generations of technology cultivation and accumulation in the field of new energy have finally ushered in the time of flowering and fruition.

The domestic new energy brand represented by MAXUS, SAIC Datong, has done things silently and made a blockbuster. With the spirit of hard work and steady progress, it has been exported overseas and staged an over-burning reversal.

Looking at today’s new energy field, we have undoubtedly stood on the cusp of a new era.

In the new era, SAIC Chase MAXUS has stood firm at the high end. The road to the future has never been smoother.

1905 movie network news On February 21st, the film directed by and starring Deng Chao,,,,,, and so on was released "Salute! At the end of the title, the "famous scene" of China table tennis history reappeared one by one in the song "Glorious Road", and the "memory killing" of table tennis in past dynasties attracted people’s tears. Previously, the main players of table tennis in active service also cheered for the film under the leadership of Liu Guoliang, chairman of the Chinese Table Tennis Association. Players of all ages interacted from a distance, and the spirit of table tennis in China was passed on. The film is now being shown nationwide.

Opening the Glorious Moment of China Table Tennis from Rong Guotuan and Reproducing China Table Tennis "Glorious Road" for 71 years.

"117 world champions and 254 gold medals." — — "China table tennis Jedi counterattack" "salute! The legend of table tennis history in China has been digitally recorded in the first frame of the egg at the end of the title. Since the establishment of China Table Tennis Team in 1952, the historical curtain of table tennis in China has been opened. Rong Guotuan, the legendary table tennis player who won the first men’s singles world championship for China at the World Table Tennis Championships in Dortmund in 1959, was the first world champion in the sports history of New China. Since then, table tennis fever has swept across the land of China, and the ups and downs of the national table tennis legend has also opened. Clockwise jump to 1961, the 26th World Table Tennis Championships was held in Beijing, which was the first time to host a world competition since the founding of New China. Starting from this World Table Tennis Championships, the focus of world table tennis began to shift from Japan to China. At this World Table Tennis Championships, China won three championships, namely men’s team, men’s singles and women’s singles. Qiu Zhonghui, the champion of women’s singles, became the first person in China to win the world women’s table tennis championship, and also the first women’s world champion in China — — China’s first men’s and women’s world champions were both won through table tennis.

The road to glory is not always smooth sailing. In the 1980s, European men’s table tennis launched an attack on China. In the early 1990s, swaythling cup, the highest honor of the men’s table tennis team, was won by the Swedish team for three consecutive times. This also achieved the "Jedi counterattack" of China Ping-pong in the 1995 Tianjin World Table Tennis Championships, winning all six gold medals in men’s team, women’s team, men’s doubles, women’s doubles, men’s singles and women’s singles. On the podium of the men’s team in the’ 95 Tianjin Video Game with the ending egg, the "General Five Tigers" who finally won the championship was even more energetic against the background of swaythling cup, the head coach. Since then, China men’s table tennis has gone through the Gemini era of Liu Guoliang and Kong Linghui, the Gemini era of Wang Liqin, Wang Hao, Ma Lin and Ma Long, and then ZhangJike, Xu Xin and Fan Zhendong have become the mainstay of table tennis. In women’s table tennis, Wang Nan, Zhang Yining, Li Xiaoxia, Ding Ning … … Generations of legendary women’s table tennis players have firmly held the title of "Big Devil" in their hands. The egg at the end of China Ping-Pong’s Jedi Counter-Strike is a history of China Ping-Pong, and scenes of China Ping-Pong are reappeared in a panoramic view. Everyone will feel shocked when they see these photos. Table tennis in the past dynasties "Memory killing "brought tears to eyes.

"One Handsome and Five Tigers" Played the Classic Battle of Turning Defeat into Victory, the most exciting home for Tianjin’s achievements in 1995.

The Jedi counterattack of China Table Tennis tells the story that Dai Minjia, a coach studying abroad, volunteered to return to China in the early 1990s when the men’s table tennis was crushed by the "European powers" and led the veteran recruits to launch a counterattack against the "powers" in Tianjin to save the men’s table tennis. In 1990s, China men’s table tennis suffered a low ebb, losing cups in three consecutive World Table Tennis Championships, and even the team performance once fell to the seventh place in the world. In 1995, Tianjin unexpectedly won the qualification for hosting the World Table Tennis Championships, which also became the best time for China’s table tennis Jedi to fight back. Given the favorable weather and geographical location, human harmony has become a "roadblock" in front of China men’s table tennis. The "One Handsome and Five Tigers" in the film have different images and distinct personalities. They are not afraid of pressure in the face of great pressure and difficulties, and jointly performed a thrilling cup-winning battle. The Tianjin World Table Tennis Championships in 1995 has also become the most exciting home.

Dai Minjia, the "devil coach", used his troops like gods to build five "problem players" with their own strengths but no shortage of shortcomings into a teacher of hope who dares to fight, can fight and can fight. Absolute main force in the team — — Bai Min, the "leading brother", was injured in the shoulder and resisted the pressure at a critical moment that might ruin his sports career. Huang Zhao, the "most beautiful boy" who returned from "stealing a teacher" in Europe, was older, but he kept a key point with rich practical experience; Gong Feng, a "secret weapon" hidden in the snow for four years, has myopia of more than 1000 degrees in both eyes, but he has mastered the stunt of "combining attack and cutting" to beat the top players in Europe; Only 16-year-old Hou Zhuoxiang and Dong Shuai, the "future champions" and "Ping-Pong Moonlight", who showed super dominance, launched an impact from the youthful power on their opponents. As the highest comprehensive word-of-mouth evaluation of the new film released since February, this annual word-of-mouth work of "Good Laughter and Tears, Enough Burning, Enough Cool" has been unanimously recognized by the media, film critics and ordinary audiences with its ups and downs stories, carefree competitions and inspiring ping-pong spirit since its release.

The film "China Ping-Pong Fight Back" is directed by Deng Chao and Yu Baimei, starring Deng Chao, Sun Li, Timmy Xu, Duan Bowen, Cai Yida, Ding Guansen, Sun Jilun, Aruna, etc. The film is now being shown in the country.

# Article First Challenge # Will new energy vehicles replace fuel vehicles?

Different people have different views on whether new energy vehicles will replace fuel vehicles.

Wang Qing, deputy director of Market Economy Research Institute of the State Council Development Research Center, predicted that by 2025, the annual sales volume of new energy vehicles in China will reach about 17 million, and by 2030, the market share of new energy vehicles will exceed 90%. This means that in the next decade, the sales and influence of new energy vehicles will increase rapidly.

On the other hand, new energy vehicles and fuel vehicles have their own application scenarios. In the short term, new energy vehicles may not completely replace fuel vehicles. This is because there are still some problems in new energy vehicles, such as safety, charging and battery life. If these problems are solved, new energy vehicles may further expand their market share.

However, in the long run, it is an inevitable trend for new energy vehicles to replace fuel vehicles. With the continuous progress of technology and the enhancement of environmental awareness, new energy vehicles will be applied in more fields, including passenger cars and commercial vehicles. At the same time, the policy is also promoting the development of new energy vehicles. For example, some cities have gradually stopped selling fuel vehicles.

To sum up, new energy vehicles may replace fuel vehicles at some point in the future, but this process may take some time. In this process, fuel vehicles and new energy vehicles will

Coexist and compete with each other.

When it comes to exercise, many people are worried about hurting their knees.

So what kind of exercise hurts the knee the most?

The answer is

Sitting for a long time hurts your knees the most!

Long-term sedentary articular cartilage will gradually lose nutrition and "starve to death"

So exercise properly.

To prolong the life of the knee.

But the premise is to master scientific methods.

Avoid unnecessary damage.

Climb mountains and stairs

Risk of knee injury: ★★★★★★★

When going up the mountain (stairs), your knees will bear about three times your own weight.

When going down the mountain (stairs), the knee will not only bear the impact of the ground, but also increase the wear of the knee.

Therefore, it is not recommended to climb mountains and stairs as daily exercise.

Click on the picture below to see the correct posture of going up and down the stairs.

Key points of climbing without hurting knees:

The center of gravity is slightly forward when going up the mountain and slightly backward when going down the mountain.

Hold the railing to help or use the trekking pole.

Knee injury, good leg first when going upstairs, bad leg first when going downstairs.

Tip: Old people, overweight people and people with knee injuries are best to crawl less. Don’t insist on climbing if your knees are uncomfortable.

rope skipping

Risk of knee injury: ★★★☆☆☆

The risk of skipping rope to knee joint is mainly related to the venue.

Generally, the concrete floor downstairs in a residential area can’t provide an effective buffer for the impact force when skipping rope falls to the ground, and it is easy to hurt the knee for a long time.

Key points of skipping rope without hurting knees:

Choose plastic floor or cement floor to lay plastic mats.

When jumping, keep your feet close together to avoid bending your knees greatly.

The take-off height is 2 cm ~ 4 cm, so as to ensure that the skipping rope just passes through the soles of the feet.

Shake the rope with wrist strength and keep the big arm close to the torso.

jogging

Risk of knee injury: ★★☆☆☆

Jogging rarely causes knee injuries as long as it is not excessive.

A few people with obvious O-leg, X-leg deformity or knee joint disease and overweight should exercise reasonably according to the doctor’s advice.

Key points of running without hurting knees:

Warm up for 5-10 minutes before jogging, and run for 30-60 minutes every day, without paying too much attention to the distance.

Lean forward slightly, swing your arms naturally, and touch the ground with your forefoot.

Keep the speed "breathing, heartbeat is slightly faster but you can talk normally"

Plastic ground and asphalt road are selected for the site, and cement ground is not recommended.

Tip: Treadmill needs to be used with caution. If the setting is unreasonable and the speed is too fast, it is difficult for the average person to keep up with muscle strength and coordination after fatigue, but it is easy to get injured. In addition, the weight is too large, and the injured knee joint should be guided by a doctor.

At the same time, don’t be a "weekend hero" and suddenly go to exercise. Exercise should be gradual, gradually increase the amount, and the weekly increase should not exceed 10%. Don’t be a "weekend hero" and suddenly exercise.

a kind of traditional Chinese shadowboxing (tai chi chuan)

Risk of knee injury: ★★☆☆☆

Some people think that Tai Ji Chuan’s squats like "Ma Bu" will put too much pressure on his knees.

As a matter of fact, many scientific studies actually show that playing Tai Ji Chuan twice a week can not only protect the knee but also relieve psychological stress.

Key points of Tai Chi without hurting knees:

You need to warm up before playing Tai Ji Chuan.

Don’t squat too much in pursuit of beautiful movements.

You need to stand on one foot or rotate your body slowly.

Once knee discomfort occurs, don’t endure it and stop immediately.

Ride a bike

Risk of knee injury: ★★☆☆☆

When riding, people’s weight mainly presses on the seat cushion, and the force on the knees is relatively small, which also helps to strengthen the muscles around the joints.

However, if you ride too hard or take some wrong riding posture habits, it will also have certain health risks to your knees.

Key points of cycling without hurting knees:

Adjust the height of the seat to: when the foot steps on the lowest position, the knee joint slightly bends about 170.

Hold your head high while riding, keeping your knees and toes facing forward.

Keep riding at a constant speed, and don’t suddenly increase the speed by force.

Exert your thigh, and step on the pedal with the first third of the sole of your foot.

Tip: If there is obvious discomfort in front of the knee joint when riding a bicycle, it is necessary to minimize such activities.

Click on the picture below to see the details of riding a bike correctly.

swim

Risk of knee injury: ★☆☆☆☆☆

When swimming, the body is basically parallel to the water surface, and the knee joint is basically free of load, so it is best for the knee joint.

However, patients with knee injuries should avoid breaststroke as much as possible. Water resistance will impact the knee joint when breaststroke kicks, and long-term high-intensity breaststroke may aggravate the symptoms.

Tip: Freestyle and backstroke are more recommended to protect the knee joint.

Can knee pads help maintain your knees?

Many functional knee pads only sell a conceptual thing, and one thing that all functional knee pads do is actually heating. Keeping warm is a very important part of knee joint maintenance, because the joint itself is afraid of wet and cold.

Therefore, normal knee pads have two main functions.

1. Keep the knee warm

2. Increase the stability of joints.

If the functional kneepad is non-invasive to the knee joint, it is actually no problem to use. However, some people may be allergic to drugs for knee pads, so they need to be careful.

Knee pads used in osteoarthritis, the most important function is to keep warm;

The main function of knee pads used in traumatic arthritis is to provide extra stability for joints;

Primary synovitis and gouty arthritis may not be particularly important for the use of knee pads.

point out

1. Don’t rely too much on knee pads.

Long-term dependence will lead to muscle atrophy inside the joint, which is actually more unfavorable for the protection of the whole joint.

Especially for relatively young people, we must not rely too much on knee pads, but should make muscle strength stronger.

2, the temperature must not be too high, not too long.

3. Observe whether there is drug allergy in time.

4. Don’t wear too tight knee pads.

Too tight kneepads can easily lead to blood stasis, resulting in poor blood return, which may lead to thrombotic diseases of lower limbs, which may even be fatal.

What is culture? What does culture mean? This has to start with ancient Chinese. Wen is a generic word of Wen. As a noun explanation, text is texture, representation and trace. As a verb explanation, the text is interlaced, described and portrayed. Astronomy, for example, means that celestial bodies are scattered all over the night sky and staggered, naturally forming a big picture of stars.

Xinghan brilliant

Oracle Bone Inscriptions shows that on the left is a man facing west, and on the right is a man turning east, just like a man tossing and turning while sleeping. It means that things change, change and come into being. Including the transformation from one form to another, or even another thing. For example, actors make up, incarnate everything, and educate all the people.

the banlance of yin and yang

Based on the exquisite ancient prose above, we believe that the meaning of culture is like that of people who engrave chapters, which are staggered and turned into a fine chapter. The result of tattooing is culture, and the text is transformed. The purpose of tattoo is to change, and the text is to change it.

keep on chipping away/work with perseverance

The extended meaning of culture can mean using tools and wealth that change life, such as Neolithic culture, agricultural culture, rural culture, industrial culture and modern culture.

The extended meaning of culture can also indicate the information or customs of transforming ideas, such as Confucian culture, Taoist culture, Buddhist culture, Mozi culture and other Chinese excellent traditional cultures, as well as Japanese samurai culture, western jungle culture, merchant culture and other animal cultures.

Use culture to change people.
