Another outstanding achievement, the liberation power won the international standard of the internal combustion engine
About ISO/TC70 ISO/TC70, the "International Organization for Standardization Internal Combustion Engine Technical Committee", was established in 1949. Mainly responsible for the research and standard revision of the international technical standards system for internal combustion engines and their components. There are 2 sub-technical committees and 15 working groups. At present, there are 45 member state groups including China, France, Germany, Japan, Italy, the United States, and the United Kingdom, which are responsible for managing 63 international standard projects. About ISO 3046-6 ISO 3046-6, "Reciprocating Internal Combustion Engine Performance Part 6: Overspeed Protection", is one of the standard items of the ISO/TC70/WG4 Performance Working Group. The project was submitted by the Liberation Engine Division in 2017 and was approved for discussion. The project is represented by the business unit on behalf of China as the leading drafter, and 19 registered experts from 6 member states are jointly assumed by the working group. Project cycle: January 2018 to January 2020. Meeting overview During the ISO/TC70 International Standards for Internal Combustion Engines, the ISO/TC70/WG04 Performance and Test Working Group meeting was held on October 25, 2019. Luo Cong and Tang Lifeng, representatives of the Liberation Engine Division, participated in the meeting as registered experts of the working group. The meeting was chaired by Tang Lifeng, secretary of the working group. Representatives from China, Italy, Japan and other countries attended the meeting. At the meeting, the review and discussion of ISO/3046-6 "Reciprocating Internal Combustion Engine Performance Part 6: Overspeed Protection" received comments and treatment during the DIS (review) voting stage, and the participants approved the official standard text revised by the draft standard. The FDIS (Publishing) vote will be submitted and completed on November 15, 2019. On October 25, 2019, the 34th International Conference of Internal Combustion Engines Standards Committee of ISO/TC70 was officially held. 24 representatives from 7 countries including China, France, Germany, the United States and the United Kingdom attended the event. Luo Cong and Tang Lifeng from the business divisions Participated in this meeting as a representative of China. On behalf of the ISO/TC70/WG4 working group, Luo Cong conducted a work summary and submitted a working group meeting to discuss the resolution and was unanimously approved by the General Assembly. The international internal combustion engine standard, which is marked by Liberation Power, was formally approved. It is understood that ISO 3046-6 specifies the general requirements and definitions for overspeed limiting devices that protect reciprocating internal combustion engines and their drive machinery. In the main performance index standard of the original mechanical over-speed protection device, the current content of the electronic control system for the over-speed protection system in the internal combustion engine field is added, and the technical content of the electronic control system is added, and the latest IEC standard for electrical safety protection of mechanical devices is cited. It can meet the requirements of the latest international overspeed protection. The formulation of this standard not only solves the ageing problem of the ageing, but also guarantees the effectiveness of the standard. It has also expanded the scope of the standard to meet the growing market and use needs. It is also compatible with the recently revised ISO3046 series of standards, reflecting the state of the art in the field of international internal combustion engines. It not only helps to ensure and improve the quality of internal combustion engine products, but also promotes the technological progress of the internal combustion engine industry. It is more conducive to the universal exchange of products to promote international trade in internal combustion engines and increase social and economic benefits.
