Zusammenfassung:	Systems and methods are provided for preheating emissions control devices prior to engine startup using a heating element and a flow control device operable to provide a fluid flow, such as a compressor or a turbine. One exemplary method of heating an emissions control component prior to engine startup involves opening or otherwise operating a valve to provide a path for fluid flow to the emissions control component, operating a flow control device to provide the fluid flow through the path, and activating a heating element upstream of the emissions control component to heat the fluid flow to the emissions control component.
