In Sinotruk Science and Technology Building Park，Every night is a scene of bright lights.，Someone is checking the data all night long.，Some people stay up until their eyes are red just to solve a difficult problem.。They eat and wear all night，An indefatigable look，Showing an almost obsessive passion for detail.。If you go near them,，Will be their body that dare to fight.、Willing to fight hard by the deep shock.。
This kind of ruthlessness may come from the pursuit of perfection.。
In Sinotruk，There is one that is mainly composed of“After 90”Form a team，They have been fighting in the front line of the three high tests all the year round.，Follow“Plateau、High temperature、High and cold”Traces of extreme weather。Winter of 2023，They came to Mohe.——The northernmost city in China，The extreme cold test lasted for more than 90 days in the temperature of nearly 40 degrees below zero.。
Extreme rigor
Come to Mohe，It is because of the low temperature that Sinotruk's three-high test team wants.。
“This year, we had planned to conduct an extreme cold test in Hailar.，But 2023 is a mild winter.，The temperature in Hailar is not low enough.，It's only about minus 25 degrees.，So we resolutely chose to move to Mohe.。”Sinotruk Three High Test 2023—The person in charge of the cold test site in 2024 said.，“Cold test has strict requirements on the ambient temperature.，We will never settle！”
“For example, the cold start test is below the Vehicle ambient temperature of minus 35.，The process of starting the Vehicle by letting it sit for more than 24 hours。”The three-high test engineer responsible for engine calibration said.：“If it's above minus 35 degrees.，It can't be called a high cold start test.。”
The extreme cold really makes for an ideal test temperature.，But the extreme cold also brings double tests to people's physiology and psychology.。
“I arrived in Mohe on December 18th.，The coldest day so far has been minus 43 degrees.。You have to ask me what that feels like.？People can't stay outdoors at all.。”The person in charge of the alpine test site said.。
Anyone who has been to Mohe in winter knows the coldness.：Cold through thick cotton-wool shoes、The fluff through the down jacket，Hit people's heart and lungs from all sides.，And then spread to the limbs.；The inhaled air instantly condenses into ice in the nostrils.，The breath that comes out falls on the brim of the hat、Collar、Eyebrow hair，Form a layer of ice。Only moving can slow down the decline of heat.。
However, the test engineers crouched beside the car to measure the data.，A squat is often at least ten minutes.，And many jobs cannot be done with gloves.。“A whole car left to stand overnight，The cab was frozen more than ice.。I used to hold the computer in the cab for a short time.，Four fully charged batteries were replaced.，I can't stand it.。”Zhang Gong, who has participated in the three high tests for three consecutive years, said.，“Fortunately, the equipment is much stronger now.，Finally, I don't have to run with several batteries on my back.。”
Equipment can be upgraded，But what about people?？Still have to“Hold on by will”。Although when the test engineers are working outdoors,，The fingers are often stiff with cold.，It is impossible to operate the keyboard properly.，But they laughed and rubbed their hands together.，Continue to fight tenaciously against the extreme cold。
“We're here to do an experiment.，Even if you can't stay, you have to stay.，If you can't stand it, you have to endure it.。Every time we get a little progress on our pilot project，Whenever we see a Vehicle with optimized performance，Every time a customer's actual problem is solved,，Our hearts are full of a sense of accomplishment.。”Liu Gong, who participated in the extreme cold experiment for the first time, said.，“No matter how bad the environment is, in the face of this sense of achievement,，It's nothing.。”
“People can adapt to the harsh environment.，But the standard of the test cannot be compromised.。”In front of the standard，In the dictionary of Sinotruk people,“Must be reached”， No “ Almost ”，“Fight against the severe cold、In the heat of summer、Over the roof of the world、Always strive for the first place”It is the slogan of the three high test teams.，It is also the embodiment of the spirit of China Heavy Truck.！
Extreme tenacity
Sun Qing, 55，He is the oldest three-high test engineer of Sinotruk.。He tasted all the fuel in the car with his mouth.。The players all said.，“He's a‘There's a story’The people。”
2006，Sun Qing took part in the three-high experiment for the first time.，The first time I came to Mohe.。“I was in my thirties.，There are relatively few test vehicles to test in cold regions.。”He recalled，“It's too cold，It's not a place for people to stay.， I say ，Come here.，I will never come here again.。”Results from 2006 to 2024，From China III to China VI，He is in the three high tests every year.。“I witnessed the whole process of upgrading the whole car.，It also witnessed the three high test teams of China Heavy Truck from scratch.、The whole process from existence to refinement。”
“The three-high test is the assessment of products under the most harsh geographical conditions.，While testing products, it also tests people.，It depends on persistence.。”Sun Qing said，“Say‘No, come’，It's a little tongue-in-cheek.。As long as there is a need for the test，As long as the job requires it.，I will still rush to the front line without hesitation.，As always, we will do a good job of test support for everyone.。”
Li Junkai, 23, is a post-00s member of the three-high test team.，He is also the youngest player.，He is also recognized as a top student.。He graduated from Jilin University.，It is the first time to take part in the three high tests.。“What is the difference between the three-high test and the daily road test?，The biggest difference is the challenge of harsh environment to people.。This cold test，What impressed me most was‘Cold’，Northeasterners can't bear the cold.。But we believe，There is no difficulty that cannot be overcome.。”
Some people say that the three-high test team of Sinotruk is challenging the limit.，Even challenge death，But they answered like this.：This is an honor.、A responsibility，It is also a kind of responsibility for the product to the end.。
Make the details 100 out of sight%，If there is no extreme rigor，It's hard to focus on details.，Dripping water wears away stone to upgrade product quality；Without the ultimate tenacity.，It's hard to do 100.%，Overcome the challenges of harsh environments with a determined mind。
2023-2024 cold test，Sinotruk has invested 105 test engineers、57 complete vehicles，The test period is more than 90 days.，Every year, Sinotruk invests nearly 100 million yuan in the three-high test.。
However，They still feel that it is not enough.。“We hope that more engineers will come to the three-high test site.，Advise on our work from the customer's perspective，Point out our shortcomings.”“The voice of the customer is what we are most looking forward to hearing.，In this way, every pilot project we do will be more targeted.、More valuable”。Solid product quality is the perfect proof of every clangorous oath.。
Across ages、Regardless of gender，On every three-high test engineer，You can feel a hot flame burning.、Jumping——It is a struggle for the cause.、A firm belief in customer responsibility。This belief makes them dare to cross the mountain.、Brave the polar region，Tireless in the pursuit of perfection、Not afraid of hardship，For customers、Continuously create more reliability for the industry、More efficient、Safer、Smarter road transport solutions。
