Abstract
An exhaust control system of a vehicle includes a fuel injector configured to inject fuel into a combustion chamber of a burner of an exhaust system upstream of a selective catalytic reduction (SCR) catalyst; an air pump configured to pump air into the combustion chamber of the burner; a spark plug configured to ignite an air/fuel mixture within the combustion chamber of the burner; a fuel control module configured to, while an engine is off before an engine startup, selectively actuate the fuel injector and begin fuel injection; a pump control module configured to, while the engine is off before the engine startup, selectively turn on the air pump; and a spark control module configured to, while the engine is off and before the engine startup, selectively apply power to the spark plug and begin providing spark.
