Meeting Emissions - The Cummins Solution

The Cummins solution for meeting emissions regulations consists of a highly capable base engine with cooled-EGR, along with the Cummins Aftertreatment System a proprietary package that combines a Diesel Particulate Filter (DPF) with SCR technology to remove over 90% of particulate matter (PM).

Cummins engines and aftertreatment system are an integrated solution.  Designing and building the system in-house allows Cummins to calibrate the engine and aftertreatment system for optimum fuel economy, performance and near-zero emissions.

Cummins Aftertreatment System
Cummins Particulate Filter – uses wall-flow substrates to capture exhaust gas and remove PM or soot particles

Diesel Exhaust Fluid (DEF) Dosing Valve – allows a fine mist of Diesel Exhaust Fluid (DEF) to be sprayed into the hot exhaust stream

Decomposition Reactor – converts DEF to ammonia through hydrolysis

Selective Catalytic Reduction (SCR) Catalyst – Significantly reduces NOx to near-zero levels by converting it into harmless nitrogen gas and water vapor

Single High Capacity Electronic Control Module (ECM) – a single ECM manages the engine and aftertreatment system for optimum performance and fuel economy

A Proven Solution.
The Cummins Aftertreatment System has been proven in North America and Europe for years and has been thoroughly field-tested under the most extreme conditions.
