In recent years, the number of motor vehicles in my country has shown a high trend of growth, and the pollution caused by motor vehicle emissions has seriously affected the ambient air quality and human health. Motor vehicle emissions have become the primary source of air pollution in many economically developed regions. In the low-pressure and low-oxygen environment in the plateau areas of western China, such as Yunnan, the emission characteristics of motor vehicles are quite different from those in the plain areas. There is a saying that "the troops and horses are not moved for food and grass first", and it is urgent to solve the problem of plateau evaporative emissions!

In mid-May 2022, Feng Wenqiang, deputy general manager of TEINSO Tech, and senior leaders of China Automotive Research Institute, Dongfeng Xiaokang and Shandong Wuzheng and related project leaders, went to Yunnan for investigation and investigation on the current situation of mobile pollution sources and plateau evaporative emissions. Invited to visit and study in China Automobile Research Institute.

During the visit and investigation, Mr. Feng introduced the basic situation of the TEINSO Tech to the leaders of the participating units, expounded the influence of the plateau on evaporative emission, and conducted in-depth discussions and exchanges with the leaders on the plateau evaporative emissions.
