To meet emissions regulations, Eaton has developed an advanced exhaust aftertreatment system using a fuel-dosing system, mixing elements, fuel reformer, lean NOx trap (LNT), diesel particulate filter (DPF), and selective catalytic reduction (SCR) catalysts arranged for both on- and off- highway diesel engines. The system uses a fuel reformer to generate hydrogen and carbon monoxide to desulfate the LNT catalyst and reduce NOx emissions. The approach eliminates low conversion during regeneration and eliminates the inconvenience associated with a urea infrastructure. The company also is developing technologies to fully vaporize dosed fuel within the packaging constraints of off-road vehicles.
