ABSTRACT:
An exhaust system includes a heating element that is disposed downstream from an engine and that introduces thermal energy into an exhaust of the engine. A selective catalyst reduction (SCR) unit is disposed downstream from the heating element and filters nitrogen oxides (NOx) within the exhaust. A control module is in communication with and energizes the heating element based on temperature of the SCR unit.
