Coolant knowledge lecture hall (1): engine deadly killer scale

   [Original of Truck House] Many users only stay at the point of adding the coolant when it is lacking, and some users even use water directly to replace the coolant, which may be fatal to the engine. Let’s talk about the knowledge of coolant.

Coolant knowledge lecture hall (1): engine deadly killer scale

●  High-quality coolant is composed of various components in a full formula.

   Among the types of heavy-duty diesel engine coolant, alcohol-based coolant is the mainstream at present, including ethylene glycol, propylene glycol and so on. This kind of coolant belongs to the full formula category. It is composed of water, coolant (such as ethylene glycol) and additives (such as DCA4 patent formula).

●  The mineral content in the water medium of alcohol-based coolant is very strict.

   When there is water in the engine coolant, the generation of scale will occur more or less. In qualified coolant, the content of minerals in water medium is extremely strict, as shown in the above figure.

●  Mineral scale in water mediumformCause engine failure

Coolant knowledge lecture hall (1): engine deadly killer scale

   The main mineral in the water medium, calcium/magnesium ions, eventually form hard shells of calcium carbonate and magnesium carbonate on the surface of cylinder block, cylinder head, engine water channel and inner wall, which is scale. Often these scales are ignored by people, resulting in high temperature and local overheating of the engine, and it is difficult to troubleshoot.

●  scaleharmDeadly 1 mm scale insulation equals 75 mm cast iron.

Coolant knowledge lecture hall (1): engine deadly killer scale

   According to the data of Cumnins Filtration research, 1 mm thick scale has the same heat insulation effect as 75 mm cast iron material with the same area. This is equivalent to the formation of a deadly thermal insulation layer in the engine cooling system, and the engine components can not get the necessary cooling, and the life and wear are greatly increased.

●  Scaling measures, cooling system maintenance is not the only treatment.

   It must be noted that cleaning scale is not a wise maintenance measure. Because in the engine cooling system, all kinds of materials are in contact with coolant, such as aluminum/aluminum alloy, rubber, cast iron and copper. A single cleaning agent will also cause damage to other components.

●  To prevent scale formation, it is necessary to adhere to high-quality coolant and correct maintenance.

   Modern high performance diesel engine is absolutelyIt is forbidden to add water to the cooling system.Irreversible damage will occur after working for 100 hours.

   Different brands of coolant cannot be mixed.Even those with similar coolant components cannot be mixed.

   Coolant needs to be checked regularly.The liquid level of the coolant used for a long time needs to be detected. Under normal circumstances, it is forbidden to add supplementary pure water, especially hard water (well water, river water, including tap water). In case of emergency, distilled water and purified water can be added. When water accounts for more than 30% of the cooling liquid, the formation of scale will be very serious and should be absolutely prohibited.

   Change the coolant regularly., add a coolant filter if necessary.Protect the engine with high-quality coolant.

●  summary of the chapter

   Scale is only one of the common faults in cooling system, but the harm caused is serious. In the final analysis, the formation of scale lies in the quality of water itself in cooling liquid. You can’t use water instead of coolant, don’t use inferior coolant, and avoid replenishing unqualified water. This is the basic condition. For the basic knowledge of coolant, please pay attention to the next issue, "How is the corrosion/cavitation/cavitation of cooling system formed?" .

Jackie Chan’s "Zodiac 2" is officially approved, and Jaycee Chan is expected to move behind the scenes

"Zodiac" has won 880 million box office


    1905 movie network news On June 17, the State Administration of Press, Publication, Radio, Film and Television announced the national film script project information for late May, and Jackie Chan’s new film "Zodiac 2" was on the list. According to what Jackie Chan said before, Jaycee is expected to participate in the script creation of the film, and the film is also very likely to become Jaycee’s first job after taking drugs. It also paved the way for Jaycee to move behind the scenes. In addition, the plot of Wang Xiaoshuai’s latest literary film "Land" was also exposed for the first time. It is worth mentioning that after encountering Waterloo, director Wang Xiaoshuai once again directed a film that still seems to have no commercial prospects.

 

"Zodiac 2" project approved, Jaycee Chan is expected to start construction after taking drugs

 

    Jackie Chan’s self-written, self-directed and self-starred film has won a high box office of more than 800 million yuan. After three years, Jackie Chan’s big brother has made a comeback and re-created the sequel to "Zodiac". It is reported that the film will continue the story of the previous work, telling the story of JC (Jackie Chan) stealing secrets in the Eastern European base. Angry, General Vasily ordered that the secrets must be recovered and sent the "base 2 team" Maka and Chaba to find the story of JC.

 

    Although Jackie Chan is currently the only one in the screenwriter column of the film, Jackie Chan’s early brother revealed in an interview that he hoped to train Jaycee Jaycee as a director or other behind-the-scenes work, and Jaycee Jaycee also expressed his desire to participate in the script creation of "Zodiac 2". "Zodiac 2" is expected to be Jaycee Jaycee’s first job after drug use.

 

    It is unclear whether the cast will return to filming, but the new "Dragon Girl" will be the focus of attention. The only certainty is that singer Sun Nan will star in "Zodiac 2". Jackie Chan had earlier promised Sun Nan a role as a profiteer in "Zodiac 2".

Wang Xiaoshuai once criticized "Intruder" for being the focus of the industry

 

Wang Xiaoshuai directs the literary film "Land" again, and the market prospect is worrying

 

    In April this year, Wang Xiaoshuai’s "Interloper" suffered a setback, and only got 1.3% of the film volume on its first day. Wang Xiaoshuai published a letter to the audience on Weibo "in a fit of rage". He said sadly that "this may be the best era for commercial films, but it may also be the worst era for serious films." At the same time, he also urged the audience to "please support me!" But unfortunately, the "Interloper" still did not improve and continued to be at the bottom.

 

    Although it has gone through the dilemma of difficult to get a literary film, Wang Xiaoshuai still has to carry it to the end. His latest masterpiece "Land" has been officially approved and is still a literary film. "Land" tells the story of a village in Shaanxi Province where almost all the villagers go out to work, leaving only 60-year-old Chen Xigui and his wife to live together, farming and living a simple life. The prosperity of the big city makes the old couple helpless. They feel that their family is still good and the land is good. It seems that only when their feet are stepped on the cultivated land can they feel a solid story. From the plot summary, the movie "Land" still has no "appearance" of the film, which can’t help but sweat for Wang Xiaoshuai.

Huawei has won another international car company! Toyota will use Huawei to "smart drive"

Recently, according to online news, Toyota may adopt an intelligent driving scheme jointly developed by "Toyota+Huawei +Momenta". This scheme may be provided by Huawei with high-level intelligent driving hardware and Momenta with software solutions, which is different from the HI mode in which Huawei provides a complete set of solutions.

Huawei and Toyota have the foundation of intelligent cooperation. For example, the ninth generation Camry car system of GAC Toyota was jointly built by Toyota and Huawei. This car is equipped with Qualcomm Snapdragon 8155 car chip, and the smoothness of the car has been greatly improved compared with the old models.

It is believed that the cooperation between Huawei and Toyota in the field of intelligent driving was also based on the previous cooperation.

Momenta is actually an old friend of Toyota. As early as March 18, 2020, Momenta, an autonomous driving company, announced that it had reached a strategic cooperation with Toyota to provide Toyota with high-precision maps and update services based on camera visual perception technology, and to promote the commercial landing of Toyota’s Automated Map Platform (AMP) in China.

At the same time, Momenta also provides a solution for the high-order intelligent driving of Zhiji automobile. Zhiji’s high-order intelligent driving is based on hardware perception including laser radar, and now it can realize high-speed/urban expressway and intelligent navigation assistance function of urban roads.

Therefore, it is not a big problem for the intelligent driving scheme jointly developed by Toyota, Huawei and Momenta to realize the functions of high-speed/urban expressway and even urban navigation.

Moreover, both Huawei and Momenta have rich experience in the research and development of high-order intelligent driving systems, and it is also possible to get on the high-order intelligent driving system for Toyota’s new models in a short time.

Now it has entered the second half of the intelligentization of new energy vehicles. Many domestic new energy brands have equipped their own vehicles with intelligent cockpits and high-order intelligent driving systems. For example, Tucki, Aouita, Wenjie and other brands have realized the urban intelligent driving function without relying on high-precision maps.

It can be said that intelligent equipment is an indispensable part of new energy vehicles today, and domestic consumers pay more and more attention to the intelligent function of vehicles.

Traditional European car companies, such as Volkswagen and Audi, have also cooperated with new China brands, such as Tucki and Zhiji, to jointly develop new cars, and equipped them with intelligent cockpits and advanced intelligent driving systems from Tucki and Zhiji.

Toyota chose to cooperate with Huawei and Momenta at this time to develop a new car equipped with high-end smart driving, which is also the general trend. At the same time, we can see that Toyota attaches great importance to the China market, hoping that its own new energy vehicles will be more competitive in the domestic market, and these new vehicles can be pushed to the world in the future to enhance the global competitiveness of Toyota’s new energy vehicles.

The editor said:

When many consumers talk about Toyota, they will still think of its fuel vehicle products. Moreover, from the monthly sales situation, the sales of two pure electric vehicles under Toyota are not ideal, and Toyota’s new energy transformation process has indeed encountered certain difficulties. If Toyota really cooperates with Huawei and Momenta to engage in high-level intelligent driving, it can really improve the market competitiveness of Toyota’s new energy vehicles, but it will test the time for the relevant joint development models to be launched on the market.

At present, many traditional car companies are speeding up the transformation of new energy, and adjusting the transformation of new energy. Toyota needs to seize the opportunity and launch new cars at the right time to have a greater chance to compete with a number of competitors.

As for the news of Toyota’s tripartite cooperation with Huawei and Momenta, it is said that Toyota will officially announce it to the public during the Beijing Auto Show, so we will look forward to whether Toyota will use the high-level wisdom of Huawei and Momenta.

Guarding "Children from the Stars"

Red Net Moment Loudi February 21st(Correspondent Zhou Junliang) Recently, the police of Wanbao Police Station of Louxing Branch of Loudi Public Security Bureau successfully helped a lost child find his family and guarded a "child from the stars".
At 10 o’clock on February 19, the Chengnan Police Office of Wanbao Police Station of Louxing Branch of Loudi City Public Security Bureau received an instruction from the police station: "A child was lost near Jing ‘an Street in Loudi City, and asked the Chengnan Police Office to help find it." After receiving the alarm, the police contacted the alarm person for the first time, and while calming the family’s emotions, they learned in detail the physical characteristics of the lost child and the specific location before the loss. Because this 5-year-old boy suffers from severe autism, he doesn’t like to communicate with others and won’t take the initiative to seek police help, which adds a lot of difficulty to finding a job.
After arriving at the lost scene, the police and auxiliary police continued to expand the search scope centering on the lost place of the children through the combination of walking patrol and car patrol, and launched a "carpet search" in the areas where the lost children may appear, and kept in touch with the police station and other service personnel.
Hard work pays off. After nearly an hour of searching, the police finally found the lost children near a certain community. At that time, the child was running back and forth on the road. Due to the heavy traffic, police officers Zhou Junliang and Li Weiqing rushed to stop the child’s behavior and avoid traffic accidents. After that, the police took the little boy away from the road and asked about his family. During the inquiry, the little boy was emotional and unwilling to cooperate. Afterwards, the police immediately contacted the parents, and after asking and comparing again, it was determined that the little boy was the lost child. The police took the child back to the police office and handed it over to the parents. When leaving, the police repeatedly told parents that they must take good care of their children.
Police warm reminder
Parents should do the following when taking their children out to prevent their children from getting lost.
1. Keep the child in sight: Please hold the child in your hand or in your arms and pay attention to it in places where there are many people.
2. Try to prevent children from going out alone: children are young and do not have the ability to protect themselves, so it is best to have a guardian when they go out.
3. Teach children some common sense of self-help: For example, don’t panic when you are lost with your parents, you should immediately ask for help from nearby staff or police, and don’t just walk with strangers.
4. Let the children carry the contact information card with them: put a card on the young children and write down the parents’ names, contact numbers and other information. Once the child is lost, it is convenient for the police to get in touch with the parents.
5. Call the police in time in case of emergency: If you find that your child is lost, you should call the police at the first time and ask the nearby police for help.
6. For children in special circumstances, please be more patient and caring, guide, appease and accompany them, and help them find their families in time.

Rugby retired and re-employed, Tenet men conquered Nolan by "fighting dad"?

The starring role of "Black 007" that the media and fans have been chanting has not yet appeared. Tenet, which is being shown in cinemas around the world, has made black movie stars the leading role in spy movies ahead of schedule.

You, like James Bond, jason bourne, Ethan Hunt, Jack Ryan and other big-screen agents, saved the world at a critical moment.

Ordinary viewers may be curious, what is this young man who looks like NBA Rockets star Harden? Can become the leading actor of Christopher Nolan’s first spy war blockbuster.

If I told you,

Directed by John David and Nolan

Of course, Nolan can find John David Washington not only because he has a good father. In Hollywood, it is not uncommon for famous people to perform. shine on you is neck and neck with Kirk Douglas and michael douglas, Angelina Jolie and Jon Voight, martin sheen and Charlie Sheen … But more second generation stars are living in the shadow of their successful parents.

John David Washington (hereinafter referred to as John David) is also facing such pressure, but the road he has taken is somewhat special:

Six years before the release of Tenet, John David Washington was not even a professional actor. He was nearly 30 years old before he made up his mind to pursue an acting career, but after that, things went smoothly.

At the age of 34, he starred in "Black Party", which won the Cannes Jury Award and was nominated for the Oscar for Best Film. At the age of 36, he became the first black hero in Nolan’s works.

John David was born on July 28th, 1984. He is the eldest of four children. At the age of seven, he made his big-screen debut in malcolm x, starring his father. He appeared in the last scene of the film with only one line.

Looking back now, John David Washington feels very beautiful: ""

I was with my father when I was a child.

Malcolm x is a film co-produced by father Denzel Hayes Washington Jr. and Spike Lee. Being a star’s child has this advantage, and he can easily make an early appearance in his parents’ movies. Perhaps it was a late maturity. John David didn’t realize how famous his father Denzel Hayes Washington Jr. was until he was 11 years old.

Also in this year, after making a guest appearance in his father’s The Blue Devil, he stayed away from acting since then, because he had other hobbies.

John David’s big screen debut

After entering primary school, John David loved sports most and played football almost every morning. After graduating from primary school, he decided to make professional football players a volunteer.

Now he does not deny that when he made such a choice, he also had the consideration of getting rid of his father’s fame.

The tallest child on the right is John David.

It may seem to outsiders that John David has been living in the shadow of his father, but in an interview with GQ magazine, he said that he had a good time with his father.

"Sometimes my father and I play the trumpet together at home; Sometimes I dye my hair red and learn Arabic, but he won’t say anything. I remember one time, my father would accompany me shopping in new york and suddenly recited the lines from Shakespeare’s Richard III, just like in the movie, but I know he doesn’t usually talk like that. "

John David is with his father.

After entering middle school, John David’s football level has increased rapidly, leaving the category of hobbies, and his determination to break into the NFL (National Football League) has become stronger and stronger.

John David has been struggling for football for so many years, and what he wants most is that, indeed, wearing a helmet on the playground, no one knows who you are, let alone who your father is, and whether you can score or not depends entirely on your strength.

Wear a helmet and no one will know whose son you are.

John David still remembers that when he entered the NFL draft training camp as a student of Morehouse College in Atlanta in 2006, he specially reminded people around him not to tell anyone who his father was, and he wanted to win recognition by his own skills.

But after the first training, he found many people laughing in the lounge. It turned out that the local newspaper in the training camp reported his participation in the training on the front page, and his teammates who were familiar with him said that you couldn’t hide it, and you didn’t just rely on yourself.

John David is wearing a Rams uniform.

This is the helplessness of the famous family, trying hard to get rid of the influence of your father, but the media and the public will not cooperate with you.

In the 2006 NFL draft, he only got the non-draft free contract of the St. Louis Rams (now called the Los Angeles Rams). After three months, he was abandoned and signed up for the second team under the Rams to participate in the NFL European competition as a Rhein Fire player. On the sports field, no one will care who your father is.

John David is on the field.

He calmly judged that his own strength could not keep him on his career path, so he called his mother and hoped to return to the field of acting. But the mother flatly refused, thinking that she could not admit cowardice at this time. She hoped that her son would continue to insist on football and not give up. In 2009, John David switched to the Sacramento Bobcats in the United Football League. During this period, he also took time to participate in the performance of his father’s Book of Avery.

It is not easy for John David to leave football.

In an interview with GQ magazine, he recalled that he returned to his childhood room from the apartment rented by the team in 2013.

"I used to be independent, but it was really a low point at that time. Not only did I lose my job, but my football career was completely over, and everything I wanted was gone." In the two years since he came back from the competition, when he stayed at home doing nothing, he even considered using his sociology diploma to be a teacher.

Stubborn, he doesn’t want to be an actor with his father’s light. Andrew ·Finkelstein, a Washington friend and agent, heard that Denzel’s son had played rugby and asked him if he wanted to try it.

The producer of Players is Jushi Qiang Sen.

When John David was still playing ball, he especially liked watching HBO American dramas, especially Sex and the City and sopranos. For example, he especially liked edie falco’s role as his wife in sopranos, and it was a coincidence that his first acting role as an adult came from HBO.

How did Denzel Hayes Washington Jr. react when he got the chance to get HBO "The Players"?

John David Washington said: "He simply congratulated him, but made a condition that he would shoot a navigation set and then study hard when he came back.".

"Players" stills

After filming the navigation set, John David went to acting school for further study. No matter how good the genetic factor is, it is difficult to succeed without acquired training. Zoe kravitz (daughter of rock star Lanny Kravitz and actress lisa bonet) is his friend, and the two families often get together. She said that John David has become more and more confident in recent years, and she understands each other’s situation very well.

Because Zoe’s situation is very similar, her parents are both big players in the entertainment industry, and it is easier to get help from brokers and get opportunities.

But if you can’t do it well, people will think that you don’t deserve it, and that you are not as good as your parents. The pressure in this respect is much greater than that of ordinary actors.

Christopher Nolan said on many occasions that he chose John David Washington because of The Players and the Black Party directed by Spike Lee.

Tenet studio photo

If the former still depends on his own rugby background, then the latter embodies the advantages of the star father.

Denzel Hayes Washington Jr. and Spike Lee have cooperated many times. John David mentioned a detail: On the day of the script reading meeting of Black Partisans, the poster on the wall behind John David’s seat was Jazz Style, which was co-written by his father and Spike Lee.

Poster of Jazz Style

He said that the scene of the day was very strange. Nolan happened to be sitting next to the director Spike Lee at the premiere of "Black Party" in Cannes in 2018. Many years later, Spike Lee asked him if it was because of this premiere that he made up his mind to choose John David as the leading actor in Tenet. Nolan smiled and said, something like that.

The crew of "Black Party" appeared in Cannes.

In fact, Nolan saw John David’s performance in Players before he went to Cannes. At that time, Nolan didn’t know who he was, let alone who his father was. Nolan said that when he wrote a script, he rarely substituted actors, but when he wrote Tenet, he couldn’t get rid of John David’s appearance in his mind, so he arranged to meet John David, who was filming The Players.

John David and Nolan are talking and laughing.

Nolan said, "I remember that many years ago, James Bond producer Albert R. Broccoli first saw sean connery and decided that he could play Bond. After the meeting, Albert saw Sean Connery leave, like a panther or a cat. "

John David rehearsed for Tenet.

Nolan thinks that John David has some similar conditions, and his athletic ability is especially suitable for the leading actor in Tenet, such as climbing a high-speed fire truck in real shooting and realizing the scene of reversing time fighting.

Even with a background as a professional football player,

He felt that he couldn’t get up in bed several times and thought that he couldn’t finish filming. "Many years ago, I worked hard to keep my job in the NFL, but I didn’t expect to work hard to make a movie again."

But this movie is worth his effort, even if he may get hurt, because many people are rushing to get the job because of the Nolan blockbuster invested by 200 million dollars.

Tenet John David stills

In the years when he appeared in the American TV series "Players", John David deliberately didn’t attend the media publicity activities because he didn’t want to be asked questions about his father.

It was not until the publicity period of "Black Party" that he had to come out to face the reporter. Because the film was shortlisted for Cannes Film Festival, and the next year it was shortlisted for the best film of Oscar, there was a huge amount of public relations activities, which really could not be avoided.

Stills of "Black Party"

There’s another important reason for coming out: Tenet’s release this year saved the trouble, there was no grand premiere, and there was no press conference. The film was finished last autumn, and I saw that the film schedule was postponed again and again, and I was even worried that it would not be on the big screen. Fortunately, in the end, everything went as one wishes.

The father and son took a group photo in the NBA.

Before the release, the Washington family watched the whole film in the empty Warner Company screening hall and were asked what his father thought of his performance. John David Washington said: ""

In fact, while waiting for the release of Tenet, John David was not idle. He secretly starred in the romantic movie Malcolm and Maria with Zendaya, and after challenging crime movies and spy movies, he came to the field of romantic movies.

Still photos of Malcolm and Maria

Undeniably, his father’s influence and connections helped him a lot in "being a late bloomer", but Master led the door and practiced in that person.

How much John David Washington can achieve in the future can only be seen.
