When you are still chasing the pace of the country, Cummins's Sixth Technology has matured. This is not the case. Recently, Cummins China Parts and Accessories Division held a National Six Technical Exchange Meeting and the National Six Parts Exhibition with China First Automobile Group Corporation Technology Center and FAW Jiefang Automobile Co., Ltd. Pvc Pipe,Plastic Pvc Pipe,Rounded Pvc Pipe,Size Customized Pvc Pipe Ningbo Yongsheng Rubber And Plastic Products Co., Ltd. , https://www.yscnrubber.com
In this meeting, Cummins detailed the technical advantages and future product planning of the National Sixth Emissions Disposal System, turbocharger, fuel oil and filtration products, and exhibited the latest national six-emissions such as the Compact Box. Processors, turbochargers, fuel and filtration products.
Nearly 200 engineers and technicians of FAW visited the product structure and technical advantages of Cummins parts. After a two-hour block discussion session, the two sides discussed and communicated in detail the technologies and future cooperation of emissions treatment systems, turbochargers, fuel and filtration products.
So what understanding does Cummins have for the Sixth Technology?
(1) At present, the specific standards of China National Six are still in the formulation stage, but enterprises can make pre-planning and design of products according to the sixth stage standard of Europe. From the perspective of changes in European emission standards, changes in emission standards are gradual. From Euro 5 to Euro 6 standards, the most important change is the NOx emission limit. The NOx emission limit is reduced from 2g/kWh to 0.4g/kWh.
(2) Reviewing the upgrade of the past three national standards to the national four, it is the first revolutionary change, from the engine body to the installation of the SCR post-processing system; the national engine to the national five standard, the engine body does not need to change, but need to increase The amount of urea injected in the SCR system; and from the national five to the sixth, is another revolution in the engine and aftertreatment system, the engine body changes again, the need to introduce turbocharged and higher pressure common rail system, post-processing The system also adds a DPF (Particle Collector) to reduce the number of suspended particles.
(3) Basically, from the perspective of mainstream technology trends, the current post-processing system of the National Sixth adopts the DOC+DPF+SCR technology route, the temperature sensor is increased from one to five, and the NOx sensor is increased from one to two. Pressure sensors and suspended particle sensors have also been introduced.
This time, I can only spoil through here. I want to know more about the Cummins Six-standard technology. I can only visit the site like this FAW's small partner!
I don’t know anything else, but this technical exchange will promote the understanding and cooperation between Cummins Parts Business Unit and FAW Technology Center through visual display and interactive discussion, which further enhances the understanding and trust of both parties. The expansion of product cooperation has laid a solid foundation.
