What makes aftertreatment function most

efficiently?

18

The Cummins Solution

Cummins combines proven technologies to optimize aftertreatment performance without impacting engine performance and reliability.

▪ A function of our proven high-

pressure fuel injection system,

temperatures are managed

without additional hardware

and without increasing fuel

consumption

▪ Ensures higher temperatures

in the exhaust stream

▪ Enables engine brake

capabilities without additional

hardware

▪ Single pass-through design

optimizes exhaust flow

▪ Compact packaging helps

maintain hotter, consistent

temperatures across the unit

for better NOx reduction
