National Sixth Technical Conference In this meeting, Cummins detailed the technical advantages and future product plans of the S6 emission treatment system, turbocharger, fuel oil and filter products, and exhibited six emissions from the latest foreign countries such as Compact Box. Processors, turbochargers, fuel and filter products.
Cummins Emissions Processing System
Nearly 200 engineering and technical personnel from FAW visited and learned about the product structure and technical advantages of Cummins components. Later, in a two-hour segment discussion session, the two parties discussed and communicated in detail the technologies and future cooperation of emission treatment systems, turbochargers, fuel oil and filter products.
Cummins Turbo Technology
So what is Cummins’s understanding of the Sixth Technology in the country?
(1) At present, the country's six specific standards are still in the formulation stage, but companies can plan and design products in accordance with the sixth stage of Europe. From the perspective of changes in European emissions standards, changes in emissions standards are gradual. From the Euro 5 to Euro 6 standards, the most important change is the requirement for nitrogen oxide emission limits. The emission limit for nitrogen oxides is reduced from 2 g/kWh to 0.4 g/kWh.
(2) Recalling that the upgrading of the National 3 Standards to the National 4th was the first revolutionary change from only the engine body to the installation of an SCR post-processing system; when the National 4 to National 5 standard, the engine body does not need to be changed, but it needs to be increased. The urea injection volume in the SCR system; and from the country five to the country six, is another revolution of the engine and aftertreatment system, the engine body changes again, the need to introduce turbocharger and higher pressure common rail system, post-processing The system also needs to increase the DPF (particle trap) to reduce the number of suspended particles.
(3) Basically speaking, from the trend of mainstream technology, the current S6 post-processing system adopts the DOC+DPF+SCR technology route, the temperature sensor is increased from 1 to 5, and the NOx sensor is increased from 1 to 2 A pressure sensor and a suspended particle sensor were also introduced.
This time, Kang Kang can only be spoilt here. Wanting to learn more about Cummins's six-nation standard technology, you can only visit the scene like this FAW's little partner!
Other Kangge didn't know, but this technical exchange promoted the understanding and cooperation between Cummins Parts Business Unit and FAW Technology Center through intuitive display and interactive discussion, and further enhanced the mutual understanding and trust of both parties. The expansion of the cooperation of SVI products laid a solid foundation.
