The Cummins 2017 Single Module aftertreatment system combines the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems into a single canister. This MidRange system features up to 70 percent reduction in space claim and up to 30 percent reduction in weight over current aftertreatment systems. Simple and optimized Diesel Exhaust Fluid (DEF) dosing with the UL2 Urea Dosing System eliminates the need for engine coolant lines to and from the DEF injector, reducing installation complexity and allowing for easier serviceability. The injector's proprietary atomization nozzle minimizes the risk of deposit formation, and offers a freeze-robust design and improved reliability. Furthermore, a range of systems ideally sized for the engine and rating ensures the most efficient operation, for improved fuel efficiency across a diverse range of applications.
