Abstract: An integrated load bank and exhaust heater for a diesel genset exhaust aftertreatment system of the type having a diesel particulate filter (DPF) and a selective catalytic reduction (SCR) section. The load bank/heater can function as a load bank when testing the genset, as a heat source to optimize SCR efficiency, as to thermally regenerate the DPF filter.

Abstract: A diesel exhaust fluid (DEF) injector assembly is provided for use in an engine exhaust after-treatment system. The DEF injector assembly includes an injector body having a fluid inlet and a fluid outlet that delivers the DEF to an engine exhaust stream. The DEF injector assembly may also include a valve that opens and closes the fluid outlet of the injector body. An exemplary DEF injector assembly further includes an impact structure with an inclined impact surface that disperses and distributes the injected DEF into the engine exhaust stream. Another exemplary DEF injector assembly further includes a shroud that insulates the injector body.

Abstract: 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.
