摘要:
An electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature. The apparatus employs an electrically conductive catalyst carrier that is electrically heated. The carrier is provided with local hot spots to be energized. Since the heat is locally generated, the heat capacity of the catalyst carrier is small to shorten a temperature increasing time.
