将经过验证的技术带入新的层。
Regulatory emission standards vary from region to region. This is a challenge for engine manufacturers, ship builders and their customers. Manufacturers are forced to decide between reinventing the wheel in order to meet IMO III standards or making modifications to existing technology in order to meet new regulations.
Cummins is taking our proven dual-tier approach used for IMO II engine technology, adding an established SCR catalyst and giving customers the flexibility to run at IMO III regulated levels when necessary and IMO II levels when permitted. Operators will even have the ability to switch between IMO II and III mid-journey. The ability to “pause” SCR functions minimizes DEF use and the associated costs while maintaining the high level of fuel efficiency that CumminsQSK19，，，，QSK38，，，，QSK50andQSK60engines are known to deliver.
使用现有的引擎和后处理技术可提供最大的可靠性，同时以比竞争解决方案低得多的初始成本最小化停机时间。但是，依靠康明斯的好处比这更深。
强调
Higher Sulphur Tolerance
与康明斯高铁海洋发动机一起使用的后处理系统不需要低硫燃料。lol电子竞技IMO III强制执行1,000 ppm或更少的ppm，但是在非管制水域中，康明斯发动机可以在较lol电子竞技高的硫含量燃料上运行。
较低的DEF消耗
The DEF injection unit uses less DEF than competitive SCR systems, utilizing pressurized air to atomize the urea for better mixing and a more complete chemical reaction.
保持闲置的速度
Cummins solution includes an engine idle counter that displays a warning so that engine load can be increased to initiate controlled clean off for accumulated hydrocarbons.
First Fit Or Retrofit
Because of how Cummins solution has been designed, vessels using Cummins IMO II QSK19, QSK38, QSK50 and QSK60 engines can be easily retrofitted to achieve 2 g/kW-hr NOx output levels.
在海上维修
The Cummins SCR aftertreatment system provides easy access for maintenance which can be completed using standard tools and procedures.
Multiple Configurations For Easier Installation
后处理系统具有多个配置选项，因此可以将其定位以适合空间索赔。
WHERE EXPERTISE MEETS EXPERIENCE
没有人比康明斯更了解满足排放挑战的知识。我们在地球上几乎所有行业和类型的设备中一直在这样做数十年。康明斯通过其排放技术经验的结合和对柴油排放研发的巨大承诺设置了标准。我们从整个360度开始查看每种情况，检查所有选项，并考虑它们如何最佳满足每个唯一应用程序的需求。就IMO Tier III法规而言，我们已经优化了解决可靠性和可靠性的解决方案，同时提供了最大程度地减少DEF使用的灵活性。

IMO:The International Maritime Organization (IMO) regulates exhaust emissions on Diesel engines above 130 kW (174 hp). Engines used exclusively in emergency applications are exempt. IMO Tier III applies only when operating within NOx Emission Control Area. The Tier III regulation is in effect for North America and U.S. Caribbean Sea NOx ECAs for vessels built after January 1, 2016.
