Does Cummins design their own aftertreatment and other key systems?
• Yes. We design the Cummins Particulate Filter as an integrated system with the engine. Meeting Tier 4 Interim and Stage IIIB demands new levels of system integration in order to achieve very low emissions while improving performance. Cummins has access to all the key enabling technologies within our design and manufacturing resources, from aftertreatment, fuel systems, filters and electronic control to turbocharging. This forms the basis of our ‘Right Technology’ approach to Tier 4.
