  • 221-0055 eCAT INFERRED HEATER TEMPERATURE CONTROL TO ENABLE HIGH POWER HEATING DURING LOW FLOW CONDITIONS
    Publication number: 20230184149
    Abstract: Methods and systems are provided for an aftertreatment system. In one example, a method includes adjusting operation of an electric heating element based on an exhaust mass flow. The method further includes estimating the electric heating element based on the exhaust mass flow and a temperature of exhaust gas upstream of the electric heating element and downstream of a catalyst.

  • Methods and systems for an exhaust gas aftertreatment arrangement
    Patent number: 10961892
    Abstract: Methods and systems are provided for an exhaust aftertreatment system. In one example, a system comprises an air injector positioned to inject air between a first catalyst and a second catalyst in response to an oxygen concentration of an exhaust gas falling below a threshold concentration while exhaust gas temperatures are less than a threshold temperature.

  • Methods and systems for an exhaust gas aftertreatment arrangement
    Patent number: 10865678
    Abstract: Methods and systems are provided for an exhaust gas arrangement. In one example, a system comprises an air supply device arranged between a first LNT and a second LNT. The air supply device positioned to adjust an air/fuel ratio and a temperature of exhaust gas flowing to the second LNT and devices downstream thereof.

  • Methods and systems for an exhaust gas treatment arrangement
    Patent number: 10746115
    Abstract: Methods and systems are provided for an exhaust aftertreatment arrangement. In one example, a system includes a LNT upstream of an SCR with an oxygen storage component arranged therebetween, and where a rich operation of an engine is limited based on an oxygen load of the oxygen storage component when an exhaust gas temperature is higher than a limit temperature.

  • Methods and systems for an exhaust gas treatment arrangement
    Patent number: 10563556
    Abstract: Methods and systems are provided for an exhaust gas arrangement. In one example, a system includes a lean-NOx trap arranged upstream of a selective-catalytic reduction device with an air supply device positioned to inject air therebetween, wherein the air supply device is activated in response to an exhaust gas being rich and an exhaust gas temperature exceeding a limit temperature.
