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 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 economyA 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.
