Standardization of the automotive industry: results of an industry seminar in Changshu
Organization and participants of the event
Between May 27 and 28, 2025, 14 meetings of the working group to develop industry standards were held in Changshu (Jiangsu Province). The organizers were:
- Shanghai Institute of Electrical Engineering
- Nanfang Pump Industry Co., Ltd.
The following took part in the seminar:
- 103 technical experts
- Representatives of almost 90 domestic automakers
- Experts in materials, tools, equipment, manufacturing and testing
- End users of products
Simo Moto was represented by experts Wu Jianbing and Yu Haiyang.
Main areas of work
Participants were divided into two working groups (A and B) to discuss the following issues:
- Basic engine characteristics
- Energy efficiency classification
- Optimization of propulsion system design
- Development of high performance motor products
- Key Components
- Test methods
- Smart Manufacturing
- Creation of automotive Internet-platforms
Discussion results
During the seminar:
- The historical background and technical content of the new standards were presented
- Participants exchanged practical experience
- Technical conclusions were developed based on actual production data
- Industry consensus reached on key issues
Future plans
The Rotary Engine Standardization Committee has identified the following priorities:
- Ensuring a scientific approach to standards development
- Coordination of industry initiatives
- Introduction of advanced technologies
- Development of environmentally friendly production
- Strengthening the competitiveness of the Chinese auto industry
Based on the results of the seminar, a draft standard will be prepared for further consideration and implementation into production. The agreements reached will become the basis for the further development of standardization in the Chinese automotive industry.
