Beschreibung
Zusammenfassung:	A method and system for raising the operating temperature of an emissions control device of an automotive vehicle. A generator converts the vehicle's mechanical braking energy to electrical energy. The electrical energy is delivered, without electrical storage, to an electric heater that heats either the emissions control device or the exhaust gas at the input to the device.
