The National Internal Combustion Engine Standardization Technical Committee Internal Combustion Engine Emission After treatment Catalyst Working Group (SAC/TC177/WG15) (hereinafter referred to as the Working Group) was established in 2014. The Working Group has 16 member units and 18 members, and the leader unit of the Working Group is Zhongzi Environmental Protection Technology Co., Ltd. Chen Qizhang, Chairman of Zhongzi Environmental Protection Technology Co., Ltd., serves as the team leader, Zhao Yunkun, Technical Director of Kunming Guiyan Catalyst Co., Ltd., serves as the deputy team leader, and Li Yun, General Manager of Zhongzi Environmental Protection Technology Co., Ltd., serves as the secretary.

      Since its establishment, the working group has strictly followed the requirements of the "Management Regulations of the National Professional Standardization Technical Committee", the "Charter of the National Internal Combustion Engine Standardization Technical Committee", and the "Notice on the Establishment and Management of the Standard Setting Working Group", focusing on the establishment and improvement of the standard system in the field of internal combustion engine emission after treatment catalysts, combined with industry technological development and market standardization needs, and completed the "Working Group 13th Five Year Plan" standard planning, and organized the application and formulation of a series of standards in the "13th Five Year Plan" standard planning. Over the past five years, the working group has organized the development of 13 industry standards. The main ones are:

     Two industry standards have been developed and implemented: "JBT 13055-2017 Technical Requirements and Test Methods for Catalytic converters for Natural Gas (CNGLNG) engines" and "JBT 13056-2017 Technical Requirements and Test Methods for Catalytic converters for Liquefied Petroleum Gas (LPG) engines"; Three industry standards have been developed and officially approved: "Classification and Naming Specification for Exhaust Treatment Catalysts of Internal Combustion Engines", "Chemical Composition Analysis Method for Vanadium based SCR Catalysts Coated on Diesel Engines", and "Chemical Composition Analysis Method for SCR Catalysts Coated on Molecular Sieves for Diesel Engines"; Eight industry standards have been officially approved and are currently being formulated: "Diesel Engine Ammonia Oxidation Catalyst", "Diesel Engine Coated Molecular Sieve SCR Catalyst", "Diesel Engine Catalytic Particle Catcher Catalyst", "Gasoline Engine Particle Catcher Catalyst", "Gasoline Engine Particle Catcher Honeycomb Ceramic Carrier", "Honeycomb Carrier for Heavy duty Natural Gas Engine Aftertreatment Catalysts", "Technical Requirements for Recycling and Reuse of Ineffective Catalysts in Internal Combustion Engine Exhaust Aftertreatment Systems", and "Diesel Engine Selective Catalytic Reduction Catcher".

         At this point, the working group has preliminarily established a standard system for internal combustion engine emission post-treatment catalysts, with a focus on catalyst product technical standards, supported by catalyst key material carrier standards, and based on universal standards. Among them: 7 product technical standards, 2 product analysis standards, 2 carrier standards, and 2 basic standards. It basically covers the relevant post-treatment catalyst technologies that meet the current emission standards for internal combustion engines, providing standard support for the development of industry technology.

      Under the guidance of the National Internal Combustion Engine Standardization Technical Committee, the working group actively organizes and participates in industry standardization activities. In 2017, the National Internal Combustion Engine Standardization Technical Committee and the Small and Medium Power Internal Combustion Engine Sub Technical Committee held their first standardization work conference and joint conference on standard review, standardization training, project review, and standard promotion in Chengdu. In the past five years, I have participated in 15 industry standard review meetings of the Internal Standards Committee, 2 specialized standard training meetings, 2 industry standard Beijing project defense meetings, and 5 annual work meetings of the Internal Standards Committee's working groups and sub committees.

       With the strong support and efforts of all members, the working group won the title of 2013-2018 Advanced Working Group of the National Technical Committee for Internal Combustion Engine Standardization in 2018, and its secretary Li Yun was also named 2013-2018 exemplary individual of the National Technical Committee for Internal Combustion Engine Standardization.

      At this meeting, 16 member units of the Second Internal Combustion Engine Emission After treatment Catalyst Working Group were established. Among them, Wuxi Weifu Lida Catalytic Purifier Co., Ltd., Shandong Aofu Environmental Protection Technology Co., Ltd., China National Heavy Duty Truck Group Co., Ltd., Dongfeng Commercial Vehicle Co., Ltd., Beiqi Foton Motor Co., Ltd., and Kunming Yunnei Power Co., Ltd. are six newly added members.

         The Second Internal Combustion Engine Exhaust Aftertreatment Catalyst Working Group adheres to the leadership of the National Internal Combustion Engine Standardization Technical Committee (SAC/TC177) and the Emission Measurement and Aftertreatment Technical Committee (SAC/TC177/SC5), using technology to promote standards and standards to promote technology, closely focusing on the upgrading requirements of emission standards in China's internal combustion engine application field, aiming at the development trend of advanced emission technologies in international internal combustion engines, based on the actual application characteristics of China, and comprehensively implementing the "13th Five Year Plan" standard planning project of the working group, while organizing the completion of the "14th Five Year Plan" standardization planning work, and further improving the standard system in the field of internal combustion engine exhaust after treatment catalysts. During the 14th Five Year Plan period, the focus will be on developing technical standards for key carrier materials of post-treatment catalysts, post-treatment catalysts for non road internal combustion engines, post-treatment catalysts for marine internal combustion engines, and post-treatment technology standards for hybrid power.

        The second working group on catalysts for post treatment of internal combustion engine emissions will continue to actively participate in industry standardization activities, strengthen technical exchanges with other working groups, and organize investigations and analyses on the promotion and implementation of already issued standards, actively researching and solving problems in the implementation of standards. The working group also hopes to participate in international standard activities and actively strive to host the "2020 International Standards Committee".

       The second working group of catalysts for internal combustion engine emissions after treatment adheres to the industry development concept of "technology patenting, patent standardization, and standard industrialization", promotes the overall improvement of industry technology and product quality level through the construction of standard system, maintains the healthy and sustainable development of the industry, provides solid technical and product support for the upgrading of domestic gas engine emission standards, and safeguards the high-quality development of the industry.
