[Decoding "New Power Crowd"]
The key core technology is a national weapon. In the field of China’s equipment manufacturing industry, Weichai Holding Group Co., Ltd. (hereinafter referred to as “Weichai”) insists on independent innovation and has continuously made breakthroughs in the key core technologies of engines. The research and development of heavy commercial vehicle powertrain technology has won national technology in one fell swoop First prize for progress; break through the monopoly of electronic control core technology and give the engine a Pentium "Chinese core"; let high-end hydraulic technology land in China and resolve the "throat pain".
In Weichai’s journey to become a world-class, a large number of outstanding scientific and technological workers who dare to be the first, innovate, and selflessly have emerged on Weichai’s technological innovation road of forging the country’s heaviest weapon. With the "three highs" test team, The electronic control technology team and the Weichai Youth Science and Technology Innovation Team represented by the Linde Hydraulics team are outstanding representatives. They regard serving the country with science and technology as their lifelong belief, interpret the value pursuit and lofty mission of contemporary Chinese youth with youth and life, and set up the banner of "Intelligent Manufacturing in China" on the main battlefield of technological innovation.
1. Be the best engine in the world
"The core technology can't come, can't be bought, can't be negotiated. We must abandon all illusions, accelerate the process of independent open cooperation and research, and use the efficiency of'one day for two and a half days', like a'lunatic', to overcome technological problems day and night. , To break through a number of core technologies that others can’t take away.” This is a phrase often said by Weichai Group Chairman Tan Xuguang, and it is also the source of motivation for Weichai’s young technology innovation team to work hard.
In 2005, my country's first "Landking" engine with completely independent intellectual property rights was born in Weichai. In order to promote mass production of "Landking" as soon as possible, the Weichai Youth Technology Innovation Team took the lead in the industry to carry out the "Three Highs" test. The "three highs" test refers to various performance tests of the engine in the extreme environment of high temperature, high cold and plateau area, which is crucial to whether the engine can seize the market in the first time.
"Our goal is to be the best engine in the world." said Lu Wenzhi, the captain of the "three highs" test team. In the past 15 years, this "three highs" test team composed of outstanding young scientific and technological personnel with an average age of less than 30 years has been collecting data, capturing problems, troubleshooting, and finding the best powertrain under the most difficult extreme environments. Good balance point. They pursue the ultimate like scientific research "lunatics" and make unremitting efforts to be the best engine in the world.
The vast Gobi, towering Kunlun, two rivers of ice and snow. The "Three Highs" test not only tests the performance of the engine, but also tests the will of the team.
At the hottest time of the year, the Flame Mountain in Turpan, Xinjiang, the air temperature is as high as 50 degrees Celsius, and the surface temperature is as high as 82 degrees Celsius. The heat wave hits, making people breathless. In order to obtain engine test data under extreme high temperature environments, the "three highs" test team stayed here for more than a month.
At the coldest time of the year, at four or five o'clock in the morning in Heihe, Heilongjiang, water was sprinkled into ice. The "three highs" test team insisted on doing tests during this time period because this is the best time to test the engine's low temperature performance. After a few hours, everyone's fingers were red and stiff with cold, and the pain was unbearable, but they were excited for the data.
If the high temperature and the high cold test the will of people, then not only the will of the team members must be tested on the plateau, but also the limit of life.
In order to obtain more accurate data, they took the initiative to increase the engine plateau test from 4100 meters above sea level to 5200 meters. In order to obtain the first-hand data of the entire vehicle operation, they often follow the vehicle overnight to collect vehicle road spectrum data, analyze and summarize the common operating conditions of the engine, and optimize the engine system according to the data of different operating conditions; sometimes to improve the test efficiency, they even Fighting continuously in high temperature, plateau, and high cold, encountered severe tests of life and death such as earthquakes, hail, and strong sandstorms.
On October 14, 2011, the three comrades in the team, Feng Dongxu, Yu Chao, and Zhao Mengsheng, left their youthful lives in the Qinghai-Tibet Plateau forever during the plateau experiment. In the face of the sacrifice, the "Three Highs" test team did not stop. They wiped away the tears on their faces, forcibly endured the grief of losing their comrades, and continued to follow their path to complete their unfinished business.
No struggle is no youth. Since the launch of the "Three Highs" experiment, more than 1,000 young researchers have participated in it, and have carried out more than 2,100 days of special environmental experiments, with a mileage of more than 2 million kilometers, and completed the collection of 260 engine varieties and hundreds of thousands of sets of data. Sorting out and calibrating, applying for more than 90 technical patents, building the world's largest engine operating database, covering the most models, and the most demanding test environment, making important contributions to China's internal combustion engine industry to break the international monopoly and surpass the world's first-class.
2. Let the engine have a "Chinese core"
Every time he walked past the roaring Weichai engine, Yuan Yi's heartbeat would follow him unconsciously.
Her husband, Zhao Zhongyu, is a member of the Weichai Youth Technology Innovation Team. He led a team to overcome the "stuck neck" problem of engine localization-the electronic control system, and created a "Chinese core" that is constantly beating on the global power map. Unfortunately, three years ago, Zhao Zhongyu fell ill at his post and never got up.
Autonomous electronic control system is the "brain" of the engine. People in the industry call it the "Chinese chip". It has been monopolized by foreign countries for a long time and is a major problem that the country needs to break through. Breaking through one minute earlier will be able to install the "Chinese core" for the national power sooner. It is precisely because of this sense of responsibility that in 2008, the Weichai Youth Science and Technology Innovation Team was assigned to independently develop a high-voltage common rail electronic control system (ECU), which opened a path of innovation from scratch.
At that time, the young doctor Zhao Zhongyu had just joined Weichai and received a consultation call from a colleague of the electronic control station on the train. During the five-hour drive, he kept checking information and studying solutions, and hurried to the work site as soon as he arrived in Weifang.
This is a road no one has walked, no foundation, no technology, no talent. How difficult is it? Only those who have witnessed it know it best. At the technical exhibition, consultation with industry experts was simple and easy to deal with; without any experience reference, I could only read the English manual... Countless sleepless nights were overthrown again and again. The young team members raced against time and explored boldly. From the basic code writing to the integration of software and hardware, to the final vehicle system verification, a complete, world-class electronic control development method and process flow have been formed.
Qin Tao, who joined the electronic control R&D team in 2010, clearly remembers that in the test of 20 vehicles, problems such as high fuel consumption and old lights repeatedly appeared, and everyone almost collapsed.
Follow the car one by one! Zhao Zhongyu, who was in charge of the experiment, made the decision. From the Northeast to Xinjiang and then to Guangzhou, everyone eats and lives on a large truck all the way, and it takes half a year. The problems were resolved one by one, and the customers changed from suspicion to praise one by one.
In 2012, China's first high-voltage common rail electronic control system was launched in batches, breaking the foreign technology blockade, and Weichai Engine has a veritable "Chinese core".
In the Chinese market, the price of Weichai engines is 10% higher than that of major European and American competitors, and the market share is still far ahead, with a market share of more than 30% in the field of heavy trucks. "At present, our self-developed electronic control system is no worse than international giants in terms of technical indicators and performance." Qin Tao said proudly. Today, the market supporting volume of "China Core" has exceeded 600,000 units, basically replacing imports. Each engine is condensed with the hard work of the Weichai Youth Technology Innovation Team.
3. Crack the high-end hydraulic "throat pain"
"He who has hydraulic parts has the world." There is such a saying in the field of construction machinery. For China's equipment manufacturing industry, high-end hydraulic parts have long relied on imports, and a single suppression or purchase restriction by foreign suppliers will cause domestic enterprises to fall into a state of semi-stop production. Such a fragile industrial chain makes the Chinese people sigh with regret.
In 2012, Weichai acquired Linde Hydraulics, a global leader in high-end hydraulic technology. In order to promote the implementation of technology, Weichai organized a hydraulic team to exchange in Germany. Young hydraulic engineer Yang Guoxi was one of them.
When they first arrived in Germany, they were greeted with indifference and perfunctory. It turned out that a nearby factory was acquired by a Japanese company. Two years later, the Japanese took away all the technology and closed the local factory. The members of the Chinese team did not stop due to the rejection of each other, and through continuous communication, they continued to increase the business volume in China. At the same time, Weichai announced that it would build a new Linde Hydraulics plant in Germany. The German side was moved by Weichai's sincerity in developing industries and win-win cooperation, changed its attitude, and the two sides began a real technical cooperation.
In order to realize the rapid matching of Linde hydraulic products in China, Yang Guoxi led the Chinese team to sort out hundreds of models according to the characteristics of different products, and established a three-dimensional model library, which shortened the matching work that would otherwise take several weeks to two. Hours. This model library is not only promoted among the Chinese team, but the German team can also share resources.
In 2017, in order to build the "golden industrial chain" of construction machinery, Weichai launched the hydraulic powertrain project. Yang Guoxi was appointed as the technical leader of the Chinese team with his rich professional knowledge and serious work attitude, and issued a "military order". Complete prototype verification within one year. Many people think that this is almost impossible. As a result, Yang Guoxi and the team members "fight"!
"People can slowly develop to this level. We have to run!" Yang Guoxi often cheered up his companions, as did himself. When eating during the day, he held a burrito in one hand and a mouse in the other. He was still communicating with German engineers until late at night. Under his leadership, the entire team worked hard, sleeplessly, and raced against time.
In the process of localization, the Weichai Hydraulics team faced various problems such as insufficient capabilities of domestic suppliers, restricted sales of foreign equipment, and malicious competition from peers. The more sad the Kaner, the more motivated it can be. In order to realize the product supporting application as soon as possible, team members go to construction sites and mines, debug equipment, and collect data to fully meet the product needs of the Chinese market.
In order to let high-end hydraulics land in China, they did their best. In response to the differentiated needs of the domestic crawler excavator market, the team members made some adjustments to traditional German products when developing Linde hydraulic systems, especially the major changes in the casting process of the main valve of the 20-ton crawler excavator. Was questioned by the German side.
In order to prove its strength, Weichai sent the main valve prototype produced by its own casting to Germany for durability impact test. According to the current industry international standards, the maximum number of impacts in the durability impact test of this type of main valve is 2.8 million, and the main valve prototype produced by Weichai has successfully withstood 3 million tests without any quality problems.
After the project made a breakthrough, Yang Guoxi died of a sudden illness at the age of 32. He used his limited life to write the youth of struggle. With the joint efforts of Yang Guoxi and his team, China finally has its own national weapon in the field of high-end hydraulics.
How ambitious to sacrifice. Generations of Weichai’s young scientific and technological workers have adhered to the original intention of building a national brand, bursting out the vitality, vitality and creativity of technological innovation, just making the impossible possible, creating amazing miracles and leaving a solid footprint. , Accumulating upward power, let "China's intelligent manufacturing" walk into the center of the world's dynamic technology stage.

# Guangming Talent Micro Investigation#
[Struggling Youth] 260 engine varieties, more than 2,100 days of special environmental tests, hundreds of thousands of sets of data collection, sorting and calibration... In order to break through the "stuck neck" technology, the Weichai Youth Science and Technology Innovation Team regards "one day as two Half a day." Without struggle and youth, do you also have an unforgettable time of struggle?
@hyi123: As a medical staff, I have worked with many little sisters around me this year to fight against the new crown pneumonia epidemic. Although tired, bitter and dangerous, no one flinched. I want to say to everyone, sisters are the best!
@阿信: When I didn't study well in high school, I had to go to college. But when I was intern, I found out that I could only get a monthly salary of 1,000 yuan. Unwilling to sink, I decided to study hard, staying up all night to study hard, and finally admitted to undergraduate. I still remember the moment when I knew the results, I burst into tears with joy.
@南：I know a sister who has very bad family conditions. During the college period, when others could play, she did various part-time jobs. Not only did she not ask for tuition and living expenses from her family, she also sent money to supplement her family from time to time. Those who work hard are not bad luck. Now that my sister has graduated and signed a contract with a big company, I believe she will be happy in the future.
@火extinguisher: I want to talk about my father. When he was 14 years old, there were five people in his family, who were very poor. With grandpa's arrangement, he went to learn cooking. It was very hard to be an apprentice at the beginning, and it was basically a choreography. At the age of 18, my grandfather passed away, and my father was more able to endure hardships. After saving for two years, he opened a restaurant by himself. In 5 years, he not only built a new house for the family, but also sent his two younger sisters to marry. He always said that if the current suffering is meaningful, it is not suffering.
@演李老师: Before taking the art test, I made up my mind to lose weight as soon as possible! Later, I insisted on not eating staple foods as much as possible every day, only eating lean meat and low-calorie foods, and insisting on fitness. After more than two months, I lost nearly 20 catties!
