8. An internal combustion engine, comprising:
-
an exhaust system configured to receive exhaust gas from the internal combustion engine; a heating device configured to heat a portion of the exhaust system; and a control module that selectively controls an electrical load provided by the heating device to an alternator of the internal combustion engine to reduce a speed of the internal combustion engine. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for controlling an internal combustion engine, the method comprising:
-
determining a reduction of the speed of the engine is needed; and exciting a heating device coupled to an alternator of the internal combustion engine, thereby increasing a parasitic load on the engine causing a reduced speed for the internal combustion engine. - View Dependent Claims (16, 17, 18, 19, 20)
