Cummins Emission Solutions introduces new aftertreatment module

Cummins Emission Solutions has released the first product in its next-generation line of ultra-high efficiency aftertreatment systems.

The EcoFit single module is designed to be up to 60% smaller and 40% lighter compared to the EPA 2013 solution it supersedes, the company said, with the same emissions reduction performance. According to Cummins Emission Solutions, the smaller size enables better heat management and retention for improved fuel economy capability. The single-pass exhaust flow design delivers low back pressure.

The product will meet GHG and fuel-efficiency standards for EPA 2017.

“We are very proud to announce this groundbreaking platform and believe it is a game changer in the commercial vehicle aftertreatment market,” said John Carroll general mManager – Global On-Highway Business. “This product uses innovations in catalyst and urea dosing technologies unique to Cummins Emissions Solutions to deliver an ideal solution in the market.”

Advancements in catalyst technologies have allowed the diesel particulate filter to have a bigger ash capacity, permitting for increased time between maintenance events and minimal operator intervention, the company explained. Improvements in NOx reduction capabilities in the selective catalytic reduction system have been enabled by the use of the EcoFit UL2 Liquid-Only Urea Dosing System. 

OEM customers will benefit from simpler chassis integration, as the UL2 system does not require engine coolant lines to and from the diesel exhaust fluid (DEF) injector. Operators will see more efficient atomization of urea and minimized urea deposits, thus requiring fewer regeneration events while experiencing the optimal use of DEF throughout the system.

“We’ve achieved incredible results with this product through an entirely new engineering approach to aftertreatment systems,” Carroll said. “Historically, aftertreatment systems have been designed to meet emissions requirements; however, we’ve approached the development of this system to meet our customer needs first, while also meeting emissions standards and maintaining product integrity. We designed a product that will not only meet, but also exceed customer expectations.”
