Patent attributes
An exhaust aftertreatment system for a diesel-powered genset includes a Diesel Exhaust Fluid (DEF) injection system, a housing, a Selective Catalyst Reduction (SCR) section disposed within the housing and a support configured to support the exhaust aftertreatment system. The DEF injection system includes a housing having an inlet region and an outlet region. A stationary upstream mixer increases turbulence of exhaust entering the inlet region. A stationary downstream mixer increases turbulence of exhaust exiting the outlet region. The DEF injection system includes a DEF injector. The SCR section includes a housing having an inlet and outlet, an SCR catalyst mounted in the housing, and a diameter that is greater than a diameter of the DEF injection section housing. A Diesel Particulate Filter (DPF) section can be disposed within the housing between the DEF injection section and the SCR section.
