On October 17, 2025, Jia Bin, Secretary General of the China Internal Combustion Engine Industry Association, and his delegation visited Sifang Optoelectronics for inspection. Several experts and scholars from the Hubei Society of Automotive Engineering, the Hubei Society of Internal Combustion Engines, and the School of Energy at Huazhong University of Science and Technology accompanied the visit. Dr. Xiong Youhui, Chairman of Sifang Optoelectronics, and Liu Zhiqiang, General Manager of Sifang Instruments, accompanied the reception.

The inspection team visited the exhibition hall, research institute laboratory, and engine emission detection equipment production line of Sifang Optoelectronics, gaining a deep understanding of the company's progress in gas sensing technology research and development, engine emission detection equipment research and development, and industrialization. Secretary General Jia Bin highly praised the technological innovation capability and industrial achievements demonstrated by Sifang Optoelectronics in the field of gas sensing, fully affirming the positive role played by Sifang Optoelectronics in promoting technological progress in the industry.

At the subsequent symposium, both sides had in-depth exchanges and discussions on topics such as the future prospects of the internal combustion engine industry, technological development trends, emission regulation response strategies, and domestic substitution. Secretary General Jia Bin expressed his expectation that Sifang Optoelectronics can continue to leverage its technological advantages to provide localized solutions for core key equipment of internal combustion engines. Dr. Xiong Youhui expressed his gratitude for this. Sifang Optoelectronics will continue to deepen independent innovation, strengthen collaborative cooperation with industry associations, universities, and industry chain partners, and make greater contributions to the high-quality development of China's internal combustion engine industry.

This visit further strengthened the close ties between Sifang Optoelectronics and the association. Sifang Optoelectronics will take this exchange as an opportunity to closely integrate the company's innovative technology with industry demand, and through the positive promotion of "technological breakthroughs industrial applications industry progress", embark on a path of localization of internal combustion engine core equipment and intelligent sensors with Sifang characteristics.
