Weichai Group test three high test site encounter Anhui card friend Wu Shihong
Wu Shihong, an Anhui truck driver, said: "I remember that when you were in a big traffic jam on the mountain last year, you were the first one to come out to rescue the firewood. When Weichai came over, the heart, you don’t know, just like seeing your loved ones. ."
Overhaul seems to be an accident, fate is not a coincidence. The truck driver from Anhui, Wu Shihong, used the Weichai engine for all three trucks in the house. This is the fifth year of the Lu Wenzhi team's "three high" test on this engine. The so-called "three highs" refers to high temperatures, high temperatures, and high altitudes. After the test is up to standard, “ Lanqing WP13 †will meet the “National VI†standard and put it on the market.
Weichai Group test site
In the Weichai Science and Technology Exhibition Hall, a full range of engine samples developed by Weichai for decades have been displayed. Li Changxin, an old engineer who has been retiring for many years, will come back to see it from time to time. Li Changxin, director of the Weichai Institute of Technology, said that the reason why Weichai was able to get the Steyr project was not plain. The country’s decision to set the Steyr project in Weichai is also correct. In July 1983, in order to change the situation of China's auto industry at that time, “the lack of weight and lightnessâ€, the State Council decided to introduce the Steyr heavy-duty vehicle project from Austria and determined that the WD615 series diesel engine was scheduled to be produced at the then Weifang Diesel Engine Factory.
Heavy trucks in Shandong, Shandong Provincial Party Committee also did some work, the original is no firewood, and this project, and the big head in Weichai, when the introduction, the firewood dried 10,000 units. Three years later, 35-year-old Li Changxin was sent to Austria. Learn engine drawings first, then localize the drawings. For them, it's like painting on a piece of white paper. This is the initial stage of technological innovation. For a long time, China mainly relied on the introduction of foreign advanced technology, joint ventures, and market-for-technology to obtain economic development. However, the core technology is still in the hands of others.

In 1996, Li Changxin traveled to Austria for the second time. The focus of his study this time is drawing design, digestion and absorption. Weichai's technological innovation path entered the second phase. In 2004, Li Changxin, 59, went to Austria for the third time. This time he brought a group of young people to do joint research and development with Austria AVL Liszt. Among these young people, Zhang Ying is the youngest, then 26 years old. Zhang Ying, director of the special platform office of Weichai Engine Research Institute, told the reporter that the fuel system has made a high-pressure common-rail electronically controlled diesel engine. Before that, there were no electronically controlled diesel engines in China, all of which were mechanical pumps, developed from Lanqing P12 diesel. At the beginning, the technology of high-pressure common rail electronic control was used, which can improve the overall emission level.

After returning to China, Li Changxin led the team to start independent research and development. A year later, Weichai Group designed the "Blue Engine", which is China's first fully self-innovated high-power high-speed engine. Since then, Weichai Group has continued to increase investment, and the “Blue Engine†has been continuously updated and iterated.
In the 40 years of reform and opening up, from the introduction of imitation, digestion and absorption to independent innovation, Weichai completed the gorgeous "triple jump". At present, Weichai Group has more than 2,400 domestic and international products and technology licenses, and has presided over and participated in the formulation of 65 national and industry standards, making it a prominent industry leader. Tan Xuguang, chairman of Weichai Group, said: "The core technology is in our own hands, constantly improving our run from chasing to foreign brands, from a Chinese Weifang firewood to the country's firewood, and finally moving towards The world's firewood."

Brighteners have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints.
Generally, brighteners are divided into two categories, one is water-soluble brighteners, and the other is water-insoluble brighteners. The former can be used as a brightener for paper, paint, washing powder and cotton fabrics. The latter can be used for whitening of chemical fibers and plastics.
It is often divided into:
Fluorescent brightener for detergents; Fluorescent brighteners for textiles; Fluorescent brighteners for papermaking; Fluorescent brighteners for plastics and synthetic materials; Fluorescent brighteners for other purposes.
This product is especially used for the molding and processing of various plastics and plastic products under high temperature. Because of its good heat resistance, light resistance and chlorine resistance, it is a brightener for polyester fibers. Polyester, cotton and other fiber blended fabrics The whitening effect is also particularly ideal, and can be used for the whitening of polyester stock solution.
