Abstract

A method includes initiating a low engine-out NOx (LEON) mode by controlling a component of a vehicle having an aftertreatment system to decrease an instantaneous engine-out NOx (EONOx) amount. The method also includes comparing a temperature of the aftertreatment system to a threshold temperature. The method also includes responsive to determining that the temperature of the aftertreatment system exceeds the threshold temperature, disengaging the LEON mode. The method also includes responsive to determining that the temperature of the aftertreatment system is below the threshold temperature, comparing a NOx value to a NOx value threshold. The method also includes disengaging the LEON mode responsive to determining that the NOx value exceeds the NOx value threshold.
