Abstract
A combustion-electric propulsion system includes an alternator, an engine control module, and an electric aftertreatment component. The alternator is configured to receive a rotational input from a driveshaft and to utilize the rotational input to generate electric energy. The engine control module is configured to receive an input. The input corresponds to a drive command or a brake command. The engine control module is configured to enter an idle mode while not receiving the drive command or the brake command. The electric aftertreatment component is configured to treat exhaust. The electric aftertreatment component includes a plurality of resistance elements that are electrically communicable with the alternator. The alternator is configured to selectively transmit the electric energy to the plurality of resistance elements when in the idle mode such that the plurality of resistance elements heat at least one of the exhaust and the electric aftertreatment component.
