Rely on science and technology innovation to achieve the company's leap development

Recently, Yunnei Power was identified as the “Kunming Diesel Engine Engineering Technology Research Center” in the “Fourth Round of Kunming Key Laboratory and Engineering Technology Research Center” held by Kunming Science and Technology Bureau. The comprehensive strengths in R&D and technological innovation have been affirmed by relevant departments.

As a standard developer for the domestic multi-cylinder small-diameter diesel engine industry, Yunnei Power has the leading domestic research and production technology for multi-cylinder small-diameter diesel engines and natural gas engines. In 2015, Yunnei Power Technology Center was recognized as a state-level enterprise technology center and established a “four centers” including Kunming Technology Center, Eastern Technology Center, Chengdu Gas Center, Shandong Technology Center, and Technology and Information Department. The framework of the system. Among them, the Kunming Technology Center will rely on regional advantages, will establish Yunnan Yuanjiang, Shangri-La “three high” calibration test field, and build it as a plateau with the characteristics of research and development, experiment, calibration base. The company's Emissions Development Laboratory can conduct highly dynamic and steady-state atmospheric simulation experiments that can meet the ETC cycle and ESC cycle requirements for plateau emissions, as well as the 13-state mode, European steady state, ETC Cycle transients, and dynamic road simulations. The NEDC15 emission simulation test meets the high-level requirements and can meet the current requirements for the combustion development and emission development of the National IV and the State V diesel engine products; the noise laboratory can realize the acoustic power and sound intensity testing and analysis of the engine and powertrain, and Tracheal noise measurement, noise path analysis, simulated loading state noise analysis and other functions.

In terms of soft power, the company continued to improve the personnel training system through technology development cooperation with foreign leading engine companies and cooperation with industry, universities, research institutes, etc., and cultivated a high-efficiency and strong power that mastered modern diesel engine design, CAE analysis, test development, and vehicle calibration. The R&D team also passed the “Innovation Team for Research and Development of Diesel Engines for Kunming Yunnei Power Co., Ltd. for Energy Saving and Environmental Protection of Passenger Vehicles” by the Yunnan Science and Technology Department.

Science and technology are the backbone of the company's continuous progress and development. During the “Thirteenth Five-Year Plan” period, Yunnei Power will rely on Kunming Diesel Engine Engineering Technology Research Center, National Accredited Enterprise Technology Center, Postdoctoral Scientific Research Workstation and other research platforms to focus on upgrading “Five Capacity "building, relying on scientific and technological innovation to achieve leapfrog development.
