  • Publication number: 20180008932
    Abstract: A method to reduce NOx breakthrough and NH3 slip is provided when the SCR system is increasing in temperature and/or increasing exhaust gas mass flow. The method includes the steps of monitoring states of parameters of the exhaust gas upstream of an SCR catalyst where the states of parameters include at least one of the inlet temperature or the exhaust gas mass flow; identifying one of a temperature increase or an increased exhaust gas mass flow at the SCR inlet; identifying a new lower ammonia set-point or storage concentration for the SCR; and identifying the rate of NH3 consumption. The method further includes the step of determining an “intervening phase” a small dosage of DEF is continued during the intervening phase.

  • Patent number: 8141348
    Abstract: A method of controlling dosing of a hydrocarbon fuel into the exhaust gas of a combustion engine upstream of a particulate filter when the exhaust gas temperature into an oxidation catalyst upstream of a particulate filter has dropped below the light-off temperature of the catalyst.

  • Patent number: 8069656
    Abstract: One embodiment of the invention includes a method of operating an internal combustion engine system comprising an engine, an oxidation catalyst, and a particulate filter, the method comprising: determining if the outlet temperature of exhaust gas from the oxidation catalyst is below a first temperature, measuring the time that the outlet temperature of exhaust gas from the oxidation catalyst is below the first temperature, determining if the measured time has exceeded a first time period, and if so, elevating the temperature of the exhaust gas exiting the oxidation catalyst.

  • Patent number: 7650781
    Abstract: A method for verifying the functionality of the components for a diesel particulate filter system based upon engine speed, engine torque, inlet and outlet exhaust pressure at the diesel particulate filter. Various sensor signals are compared to calibratable values in memory for a determination whether the diesel particulate filter system is functional.

  • Publication number: 20090164108
    Abstract: A method to operate an electronically controlled internal combustion engine that recognizes when thermal management mode of operation is being applied to an engine but is not attaining desired exhaust temperature for aftertreatment. When the Engine Control System (ECS) recognizes that the engine in operating in thermal management mode in a futile effort, the ECS aborts thermal management mode and returns to normal operating mode.
