Gobi, Kunlun, Ice and Snow... In the limit of the ecology, they challenged the limits of the body and will with the pride of youth. Everything is just to create the "Chinese heart" that leads the international power. They are members of Weichai Group's “ Three High†experimental team , a team with an average age of only 27 years old, with half of masters and doctors. "Icefire" test bitter pleasure The engine is the "heart" of the car. A strong "heart" needs to withstand the test of various environments and various climates. The “three-high†test is an engine performance test conducted under conditions of high temperature, high altitude, and high temperatures. To carry out such a test, it can only be like an "anti-migratory bird" and goes against the law of the season. Chang Guoli, the captain of the “Three High†test team, jokingly stated that he and the team members are such “anti-migratory birdsâ€. "Remember that the first test was to go to the hot zone in summer, and it was hard to describe it with 'hot and hard,'" Chang Guoli still remembers. In September 2005, the pilot team set off to the Turpan desert soon after its establishment. Although it is not summer, the daytime is still a high temperature of more than 40 degrees Celsius, and such a high temperature is the ideal temperature for the inspection of new products. At noon every day, when the temperature is the highest and the sun is most exposed, the team members will arrive at the test site on the flaming mountain to start the test on time. At high temperatures in the neighborhood of 50 degrees Celsius, the cab is like a steamer and people are at risk of heat stroke at any time. However, in order to ensure the accuracy of the test, the team members responsible for driving and measuring data did not open the air conditioner, and the sweat from the body immediately evaporated. Chang Guoli still remembers that once a team member wore a pair of tendon shoes and walked on the asphalt road with a surface temperature of nearly 80 degrees Celsius, he did not take a few steps. The soles were melted down and stuck to the road. "The skin under the sun's sun exposure will not be black, purple, or black in a matter of minutes. Every bath will break a layer of skin." As a beauty-loving girl, Chang Guoli said generously that it was "a natural skin." ". This test is a month. This was followed by a plateau test at a height of 3,500-4,700 meters above sea level in the Golmud region of Qinghai. In another two months, the engine was cold-started in the cold of minus 50 degrees Celsius in the Heihe region of Heilongjiang Province.... Chang Guoli said that this scene of “bitter and happy†lighted up their youth. Want to compare with the world's diesel engine overlords Of the heavy-duty trucks that run on China’s land, 4 out of every 10 vehicles have Weichai engines . On many engines, there is an obscure white canister. Weichai people call this the "fuel oil chilling treasure." This is a filter. Do not look at it is small, but in the cold environment but it plays a "help" role. As soon as it heats the fuel, it re-softens the wax-frozen diesel, and it can be pressurized by an electric pump to speed up the flow of diesel fuel and allow the blocked oil to flow. Li Shizhen, the team responsible for the engine's electronic control system, told reporters that the diesel engine started from ordinary machinery to circuit control is a qualitative leap, but there is a congenital drawback, that is, poor start-up, especially in cold weather. Situation. In the initial test, the test team gave feedback to the design department on this issue. In December 2009, with the newly-designed "Hot Water for Fuel", the team members ran towards Heihe. Due to the instability of the initial performance of the product, the team members encountered the problem of “armpit†in the test vehicle. "Once the fuel is frozen, it must be cleaned from the tank to the tubing. Not only must the original oil be discarded, but the new oil must be used to exchange blood for the tubing several times." Li Shizhen said that in the low temperature of minus 40 degrees Celsius, people stand. It took about two to three minutes to freeze. Two or three people spent most of the time, clearing the oil pipes, measuring data, and after the car started, “the whole person has frozen wood.†In spite of this, no one of the players called a hardship and shouted hard. The following year, they entered the cold area with improved filters. In 2010, Weichai's engine had more of this small tank and became a leader in the domestic industry. It is this kind of insistence that in the past seven years, the experimental team has conducted tests on over 120 diesel engine types, collected and calibrated tens of thousands of data, and established a leading domestic diesel database. It is these limit tests that various technical indicators of Weichai engines can now be compared with the world's diesel engine overlords. Let the names of Chinese products ring through the world The journey of the “three highs†trials is not only a trial of harsh conditions but also a test of life and death. On October 14, 2011, it was a day that the test team could not forget... On the mountain bend road in Golmud, Qinghai Province, a Weichai test vehicle rolled over. Nearly 30 tons of sand and gravel contained three players. The front of the road was buried in a solid state. They will remain on the Qinghai-Tibet Plateau forever... They are only 27 or 8 years old and they are all children of their own family. Feng Dongxu has a daughter who is just over 1 year old. His wife is still waiting for him to come back to her daughter's birthday and take the first family portrait. Yu Chao and his girlfriend’s wedding photos have been taken. Zhao Mengsheng’s wedding invitations have been distributed by parents to friends and family. They could have escaped this robbery. Because on the first day, they had finished all the test tasks. However, because the German engineers of the equipment manufacturers must go together, this is a learning opportunity that is not always available to them. So when the three people get together, they all go. The cost of life shocked young players. That night, all the players' hands were tightly tied together. They shed tears and promised to three teammates: Rest assured, three brothers, we are a strong team and we will never give up! For the next 40 days, all the players endured tears and continued to conduct an experiment because they had a dream in their hearts: to build the best engine in the world! It is for this common dream that the young people are not far away from the plateau, fighting the cold, fighting the heat, and challenging the limits one after another, composing a moving song of youth!
