    摘要： A catalytic converter suitable for use in controlling automotive exhaust emissions including a honeycomb heater disposed downstream of a main monolithic catalyst or between main monolithic catalysts. The honeycomb heater includes a honeycomb structure with a catalyst carried thereon and with at least two electrodes provided thereon to supply a current thereto. A catalytic converter also includes a monolith catalyst for ignition which is disposed downstream of the honeycomb heater. A catalytic converter includes, in place of the honeycomb heater and the monolithic catalyst, a module which is composed of a catalyzed light-off honeycomb heater or of a honeycomb heater and a light-off monolithic catalyst. The module is removably disposed upstream or downstream of a main monolithic catalyst, or between main monolithic catalysts.

    摘要： A honeycomb heater having integrally formed and/or integrally sintered electrodes comprises a honeycomb structure having a desired honeycomb configuration, and electrodes which are integrally sintered with the honeycomb structure at predetermined positions thereon. The honeycomb heater having integrally sintered is manufactured by joining or contacting the electrode-like formed bodies to the formed honeycomb body, and then by sintering the formed honeycomb body with the electrode-like formed bodies attached or contacted thereto. The electrodes are made of the same material as that of the honeycomb body, or of a material having an electric resistance lower than that of the material comprising the honeycomb body. Alternatively, the honeycomb heater having integrally formed and integrally sintered electrodes is manufactured by preparing an extrusion of a honeycomb body as one body which has a honeycomb configuration and an electrode-like shape at predetermined positions thereon, and then sintering that formed honeycomb body.

    摘要： In a catalytic converter operating method according to the present invention, a heater is energized at a predetermined power level or above and thereby heated substantially concurrently with the operation of an engine. During the heating, an oxidizing gas is introduced into the catalytic converter. When the temperature of the heater exceeds a value at which a main catalyst of the catalytic converter or a light-off catalyst carried on the heater functions, the power level is reduced by an output adjuster and supply of the oxidizing gas is suspended.
