Cummins makes aftertreatment system smaller, more efficient

LOUISVILLE, Ky. — Cummins is coming out with a new exhaust aftertreatment module that’s contained within a single canister, offering significant size and weight savings.

The Cummins Emission Solutions subsidiary developed the smaller package, which reduces size by up to 60% and weight up to 40%.

The EcoFit Single Module also improves emissions reduction performance, according to the company. The smaller size allows for better heat management and retention, while the single-pass exhaust flow design delivers low backpressure.

“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 manager, 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.”

Cummins also announced it’s extending the cleaning intervals on its diesel particulate filters to 400,000 miles.
