Yunde Dewei's six series of power successfully conquered Kunlun Mountain

Not long ago, the Yunnei Power Dewei Guoliu series engine matched a variety of different brands of vehicles (a total of 39 light trucks) successfully completed the test of the plateau in the 'three high' in Kunlun Mountain at an altitude of 4,800 meters.

From the zero-elevation of Turpan to the Kunlun Mountain Pass at an altitude of 4,800 meters, from high temperature and hot to cold and low oxygen, the harsh environmental conditions of Kunlun Mountain are a new test for both test vehicles and test engineers. Fortunately, the engineers in the cloud persisted and successfully completed the calibration of the plateau test.

The plateau test of the cloud power is generally followed by the summer high temperature test, which takes place in the period from August to September, and lasts for one month. During this period, the engineer will target the combustion, dynamic performance, application limits of the components, emissions, etc. , as well as fuel injection systems, intake systems, aftertreatment systems, OBD monitoring systems, etc., for plateau adaptive calibration and testing.

After the test was completed, all the personnel and vehicles who participated in the calibration of the plateau test took a group photo and announced the successful completion of the calibration of the plateau test. The Yunde Dewei six-series engine successfully conquered Kunlun Mountain.

Partial test vehicle family portrait

With the blue sky defense battle started, the number of the world's most stringent national six emission regulations is approaching. Although the national implementation of the national six standards is implemented on July 1, 2020, many provinces and cities have announced that they will The implementation of the national six emissions in advance, and on July 1, 2019 officially implemented the national six emission standards for light vehicles. This is undoubtedly a huge test and challenge for domestic vehicle manufacturers.

For the cloud power, this is not only a challenge, but also an opportunity. As the current domestic engine manufacturers that can match the emission standards of the national six, the cloud actively promotes the vehicle matching and stepped up to participate in the 'three high calibration. ', intends to carry the Yunnei Power Dewey (DEV) National Six series products to the market next year with the OEMs, and occupy a place in the market.

Following the launch of a variety of models of the DEV's six-series engine in the cloud, this year, after completing the high-temperature calibration test in Turpan in July and August, Yunnei Power engineers continued to travel to the Kunlun Mountains for Dulwich (DEV). The calibration of the plateau adaptability of the series of national six engines.

In August, a number of different brands of the DEV six-series engine entered the Kunlun Mountains and went to Hoh Xil, opening a new round of plateau battles, starting from the cold regions above 2800 meters. Test calibration.

The ancients called Kunlun Mountain the ancestor of the Chinese dragon's vein, with an average elevation of 5,500-6,000 meters. The air on the mountain is thin and the temperature is low. Generally, the temperature will drop by 6 degrees for every 1000 meters, and the climate on the mountain is abnormal. It is no exaggeration to describe the weather changes in Kunlun Mountain.

However, such a bad climate not only did not scare the engineers, but also aroused their triumph. In order to obtain the test data under the extreme conditions, the engineers continued to face new challenges during the calibration process, and the altitude gradually increased from 2,800 meters to 4,800. m. From sunny to rainy weather.

In the worst working conditions, test vehicles or continuous driving, or uninterrupted test calibration, engineers in the bumpy car, constantly modify the plateau combustion parameters, and repeatedly verify at different altitudes, so that The performance of the engine is optimal at the plateau. Moreover, the cold start of the plateau is more challenging than the cold start of the plain. First, it is necessary to constantly adjust the optimization parameters at different altitudes. Secondly, the car needs to be placed in the mountain to extinguish the fire. Late, the calibration test was conducted the next morning. Although under the adverse conditions of snowing, extreme cold and so on, the vehicle finally completed the cold start test at an altitude of 4,800 meters and zero degrees Celsius, and the starting time was only 1.5 seconds.

The harsh use environment is a test for the cloud-powered DEV country's six-series engine, but it is also an indispensable step.

Conclusion

It is not easy to convert a new product into a commodity. It can even be said to be very difficult. If the product is put into the market, it can be recognized by the user. This requires continuous improvement of its own quality before the product launches, and it is scientific and rigorous. Attitude and meticulous spirit, pursuing product excellence. Ultimately, it can be recognized by the market and users.
