After completing the National Phase B certification, Cummins China took the lead in launching the Euro 6 D-stage certification and obtained the Z14 engine certificate. It obtained the first ticket for the Chinese domestic engine to enter the next stage of the EU market, and also entered the EU for the products of the OEM. The market is solid. The requirements of the Euro 6 D phase are basically equivalent to those of the National 6th B phase, but there are also some unique requirements. Cummins also considers the requirements of the Euro 6 D phase while developing the national 6 B phase product, and completes the European product for Cummins China. Six D-stage certification is fully prepared. Unlike in the past, Cummins combines a new generation of engine intelligent control technology with a more reliable hardware architecture to recommend Chinese-made products to the world based on the first to meet Chinese regulations and market demands. China R&D, facing the world Cummins pays attention to localization development. The purpose of technology research and development is "the most suitable technology is the key", supported by global resources, and deep cooperation with host manufacturers to understand the needs of Chinese users, chain research and development, chain manufacturing, whether it is product development , or product testing, and later product production, Cummins has strict unified processes and standards around the world. At present, it has more than 200 OEM customers in more than 40 countries. While applying to the Chinese market, it also helps Chinese OEMs to continuously achieve breakthroughs in the export market. Deepen cooperation and cooperate effectively The certification process of the Euro 6D phase is also a process of deep cooperation with the OEM. Under the guidance and supervision of the VCA (Vehicle Certification Authority of the United Kingdom), engine bench testing, OBD related testing, VECTO related testing and PEMS roads have been completed. After testing and other work, in April and June of 2019, the Cummins Z14 engine was awarded UN/ECE and e-mark certification at VCA (Vehicle Authority Vehicle Authority) and STA (Swedish Ministry of Transport). At the same time, Cummins' other series of engines (from 2.8L to 13L series) are also actively preparing, and some have already started the certification work to meet the certification requirements of the OEM's Euro 6D stage. “Cummins is a pioneer in the upgrading of emission technologies and a practitioner of global R&D applications. By establishing an efficient and globally unified R&D process, technology platforms can be shared among engineering and technical departments.†In the process of Euro 6 D-stage certification, the engineering teams in China, the United Kingdom, and the United States are working together to fully mobilize global R&D resources. Cummins works closely with domestic commercial vehicle companies, from the differences between China and EU regulations to specific certification requirements. Details, from an engine platform to multiple engine platforms, from engine certification to vehicle certification, Cummins' R&D capabilities in key markets around the world ensure that our customers develop the right technology for each of the different regional markets.
Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the teflon heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.

Since the implementation of the Euro 6D phase on September 1, 2018, it means that after September 1, 2019, products that do not meet the requirements of the Euro 6 D phase will not be able to enter the EU market.
