Abstract
A method of controlling temperature of an engine aftertreatment system includes directing an electric heater in the engine aftertreatment system to apply heat using a first temperature setpoint; while applying the heat at the first temperature setpoint, receiving temperature data from a temperature sensor proximate to a selective catalytic reduction (SCR) device in the engine aftertreatment system; determining from the temperature data that a first temperature is at a first threshold temperature which is less than the first temperature setpoint; and after determining that the first temperature is at the first threshold temperature, directing the electric heater to apply heat using a second temperature setpoint which is less than the first temperature setpoint.
