    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.

    摘要: The catalytic converter includes a first flow passage for an automotive exhaust gas and a second flow passage disposed parallel to the first flow passage to bypass the exhaust gas therethrough. The first flow passage contains a honeycomb heater or a heater catalyst which comprises a honeycomb heater with a catalyst carried thereon. At the beginning of an operation of any engine, the exhaust gas whose temperature is low is caused to flow through the first flow passage. When the temperature of the exhaust gas exceeds a predetermined value, the flow passage is switched from the first passage to the second flow passage.
