Abstract
A method of controlling temperature of an engine aftertreatment system includes directing an exhaust heating device in an engine aftertreatment system to apply heat to the engine aftertreatment system; opening at least one of one or more intake valves and one or more exhaust valves of an engine coupled to the engine aftertreatment system; and pulsing, by an engine starter of the engine, the engine to generate airflow from the engine that moves the applied heat from the exhaust heating device downstream the engine aftertreatment system.
