MULTIPLE HEATER EXHAUST AFTERTREATMENT SYSTEM ARCHITECTURE AND METHODS OF CONTROL THEREOF
Abstract:
A system includes an intake heater positioned in or proximate to an air intake of an engine, an aftertreatment system heater positioned downstream of the engine, and a controller coupled to the intake heater and the aftertreatment system heater. The controller is structured to operate the intake heater to heat air entering the engine for a predefined time period. The controller is structured to determine, based on information indicative of a temperature regarding an exhaust aftertreatment system, that the temperature regarding the exhaust aftertreatment system is below a predefined temperature threshold. The controller is structured to continue operating the intake heater after the predefined time period responsive to the temperature regarding the exhaust aftertreatment system being below the predefined temperature threshold.
