As more and more new products of Yuchai are put on the market,，In order to allow the engine to operate freely in a variety of changing environments,，All the time，Yuchai Passed the Adaptability Verification under Extreme Environmental Conditions，So that the engine and the matching vehicle can better adapt to different regions.、Different environmental conditions、Different road conditions、Different driving habits，Make the product self-adaptation of the engine play its potential.，Performance status to the best。Now the Spring Festival has come.，The calibration team has successfully completed the first phase of the test task recently.。

Every year，Yuchai will have high temperature.、Plateau、Cold calibration test。Yuchai Extreme Environment Calibration Team has traveled all over the country，They are“Retrograde”Migratory birds，They pursue the most stringent environmental conditions to verify engine products，I'm also testing myself.。Panting at the Kunlun Mountain Pass Insufficient Breathing Plain 50%Oxygenated air、Midsummer rush to Flaming Mountain to receive surface 70℃Roasting at a high temperature、Go to the northernmost end of China where water splashes into ice in the cold winter to carry out extreme cold verification，Every hard test and countless struggles have contributed to the growing maturity of new products and the boundless gallop after their launch.。

December fifth，Truck with Yuchai Guoliu engine、Passenger car，Depart from Yulin，He went to Hailar City, Inner Mongolia Autonomous Region, 4000 kilometers away from the northern end of the motherland, to carry out the cold calibration test.。In Hailar, Inner Mongolia，The current temperature is as low as minus 40 degrees.，The calibration team climbed under the car in the ice and snow of Hailar.、Through the snowfield，Get first-hand data on engine optimization。

  

In the next 100 days,，They're doneYCY25、YCS06、YCK08、YCY24、YCK15NVerification of 11 models，Cold start verification included、Carbon accumulation and regeneration efficiency verification、Verification of special and test problems、OBDValidate、Low temperature emission verification test and many other tests。

  

The total mileage of alpine test vehicles will exceed 300000 kilometers.，This is not just for the whole car.、The test of the engine in extreme environment，It is also an extreme test for every experimenter.。

  

The first time I led the team to participate in the cold vehicle calibration work, Cao Ke recalled.：Extremely cold outdoor conditions，Plus the impact of the epidemic.，The task of cold calibration test has been greatly hindered.。Three days after arriving in Hailar，The experimenters fell one by one.，But in order to advance the test progress as much as possible,，Still fighting on the front line.。At minus 32 degrees.，A cold cab，Hands shaking with cold，Everyone can understand the difficulties.。Only the cohesion and combat effectiveness of the whole team can overcome all difficulties.，Achieve the ultimate goal of the team。

  

“Three high”The calibration team has carefully studied、Beyond the limit、Craftsmanship，The ultimate goal is to create high-quality products for customers.，It is also the efforts of the calibration team.，Yuchai won the first place in the National Enterprise Technology Center。
