Cummins QSF3.8 Engine Overview
Cummins QSF3.8 (TIER 4 FINAL/STAGE IV)

From 100-130 hp, the QSF3.8 is paired with a Diesel Oxidation Catalyst and Selective Catalytic Reduction (DOC-SCR) system designed by Cummins Emission Solutions (CES). Cummins SCR enables oxides of nitrogen (NOx) conversion to take place at lower exhaust temperatures. CES has manufactured over 1 million SCR systems – and has more experience with this technology than any other company.
The Cummins SCR system features a decomposition tube designed to enable more effective mixing of the Diesel Exhaust Fluid(DEF) ahead of the catalyst. Additionally, for certain applications, the QSF3.8 can be paired with an SCR-only aftertreatment system.
