新的第二阶段综合系统概念

这个怎么运作

  • The integrated Rotary Turbine Control enables exhaust gases to bypass the turbine stage and enter the Close Coupled Unit after the gas has been injected with urea by the new Cummins UL4 injector.
  • When combined with the Single Module™ chassis mounted aftertreatment, the concept Integrated System has the potential to improve emissions, particularly for cold start and urban driving operations.

Integrated Rotary Turbine Control 减少热惯性,改善包装,允许高达100%的涡轮机旁路,使后处理系统能够更快地达到工作温度。
UL4剂量 定位靠近涡轮增压器,通过使用来自涡轮机滚轮的气体旋流,可以自由混合尿素。
Flex耦合补偿器 优化UL4 DERER的定位,抑制振动并提供安装灵活性。
近耦合单位 改进的催化剂设计与涡轮增压器流量范围更加兼容。
高效Holset®涡轮增压器 下一个逆叶轮,新的油封技术和热优化的轴承系统是对涡轮机,压缩机和转子系统的一些空气处理改进,以提高效率和鲁棒性。

结合工程专业知识来帮助客户解决未来的排放控制标准


The concept system has been designed to help customers address future CO2 and NOx challenges. The phase II design contains new air-handling and integrated aftertreatment architecture packaged in a single system, a first for the commercial diesel market.

RTC Valve

Optimized heat management:Up to 100% exhaust gas bypass, enabling the aftertreatment to reach operating temperatures faster and reduce NOx more efficiently.

改进的热管理:Generates back pressure for thermal management, driving Exhaust Gas Recirculation (EGR).

Turbo Technology

UL4剂量

Improved temperature control:环境温度能力提高,环境温度限制增加,最高可达160℃(有限时间),旨在实现涡轮尿素注射后。

提高可靠性:Together with the UL2.2, UL4 is one of the only liquid-only dosing systems on the market, offering freeze-robustness in its design. The system is designed specifically to prevent doser crystallization and clogging.

Dosing Technology

Flex耦合补偿器

Improved packaging:新的Flex耦合补偿器优化UL4 DOSER的定位,抑制振动并提供安装灵活性。

Aftertreatment Technology

CCU

Improved emissions integration:The close coupled aftertreatment unit benefits from higher exhaust gas temperatures to enable more effective emissions conversion. When combined with the Single Module™ chassis mounted aftertreatment, it has the potential to improve emissions, particularly for cold start and urban driving operations.
