Take heart for core

8 years of time, more than 700 a day and night stick and bitter, 160 model calibration tests, tens of thousands of kinds of test data acquisition, industry the earliest of "three high" calibration of the team, the establishment of industry first "three high" calibration bench... This series of labels, and the wind, rain and snow, gradually sink into the "three high" Yuchai calibration test team image. This is a group of heroes who shoulder the fate of the national industry.

From the beginning of 2005, Yuchai every year, high temperature plateau, alpine calibration test. In order to achieve the best results, the control engineer, design engineer, application engineer, test technicians and professional test driver team of young, like a flock of migrating birds, from south to north, and from the north to the south. However, relative to the birds always looking for the most comfortable living environment, they are more like a group of anti migratory birds, the law of the season ahead. In the summer, they stepped into Turpan Basin, climbing on the Qinghai Tibet Plateau; in winter, they go to the north of the ice and snow, Mohe polar.

A battle to fight

July 23, 2012, midsummer. When you hide in the air by enjoying the cool when, early in the morning, Yuchai Engineer Yang Fangzi will lead the first batch of the team set off from the Guangxi Yulin. Calibration of the three "rising star" preparing to test the first station - years ago trapped Chinese legend character Sun Wukong Flame Mountain, here they will Yuchai engine high temperature calibration experiments.

5 days, nearly 4000 kilometers of the long journey, the team a line finally arrived at the destination. In Turpan Basin in the flaming mountains, in "journey to the west" in the full description: 80 in the flame mountain barren cliff, crimson yunzhengxiawei, like lounging in the Gobi desert of volcanic. The reality of the Flaming Mountains, although not Wu Chengen's dangerous, but also be threatened by growing crises. "When there is a time after the flame mountain hot center" alchemy furnace ', I specifically looked at the stand in the giant of the mercury column, 73 degrees. There's no problem with this fried egg." Yuchai Engineer Ye Shengbin smiled said, he has for four consecutive years in three calibration, with rich experience, can be regarded as is "old" of all corners of the country.

Experiment is hard. Compared with the Hainan special test field, Turpan region of high temperature, the entire month of August with the highest average temperature above 42 DEG C, the highest temperature in the afternoon can be reached 48 degrees Celsius, and the air is dry, hot and humid environment worse. During the experiment, some conditions are not allowed to open air conditioning, in order to avoid wind resistance is too large, the windows are closed. "Once the air conditioner is turned off, the car becomes a veritable stove.." Yang Fangzi said.

For the first time to join the young Electronic Engineer Du Yu three calibration test, this test is dangerous. Have a test car along the highway rapid return, a sudden strong wind carrying a pebble, through the window is not strict, straight shot into the cab, was crushed his right lens, fortunately, no injury to the eye. The only 24 year old young man, just from Beijing Daxue Aerospace graduated two years, on the spot in a cold sweat. But afterwards, he smiled and said: just, this pair of glasses for four years can finally 'retire', before still not willing to."

In order to ensure the Yuchai engine in any harsh environment and mode of operation can be normal operation, this group of young 80 after the team almost torture yourself doing all kinds of test. To calibrate the passenger car in the high speed road of thermal protection function, in the vehicle loaded state, they in the high-speed road will speed as possible increased to maximum. This is extremely dangerous, a sharp turn may lead to fatal car crash. One time during the high-speed test, the vehicle to the maximum speed of more than 20 minutes, suddenly, the tester smelled a strong smell of diesel. Parking check, found the injector return tubing serious leakage, followed, they found a large number of coolant leakage. Upon examination, the original is subject to the influence of terrain condition, vehicle running quickly driven by strong winds, rolled up roadside scattered pebbles, the tank busting the five or six holes, tire also appeared cracks. Everyone is seen in front of the "horror" scared the daylights, however, will be towed to a service station repair. They began to the rest of the test.

In this field to fight the battle, they won. After nearly 20 days under the environment of high temperature calibration test, matching of Xiamen Golden Dragon, Golden Tour, Futian, Liuzhou Automobile, Dongfeng, North Ben, a number of car manufacturers a total of eight models in the high temperature environment of driving, power and overheating protection function basically reached the optimization, key parts of the various models of engine cooling systems and also in high temperature environment were fully validated, provide a large number of experimental basis for the future design work.

And the high temperature calibration tests carried out simultaneously, and the plateau calibration experiments on the Qinghai Tibet Plateau. This test, Yuchai has selected three sites, respectively Golmud suburbs, Nachitai and xidatan
