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： A heater unit includes a metallic casing, and a honeycomb heater held in the casing, comprising a metallic honeycomb structure having a large number of parallel passages extending in the direction of the flow of a gas passing through the heater unit and at least one electrode for electrical heating of the honeycomb structure, attached to the honeycomb structure. A fastening member is fitted to part of the outer surface of the honeycomb heater to stabilize the shape of the honeycomb heater and a holding member is fitted to the outer periphery of the honeycomb heater to connect the honeycomb heater with the inner surface of the casing via the holding member. This heater unit can be suitably used for purification of the exhaust gas emitted from an automobile engine, because, in the heater unit, the unpurified exhaust gas which passes through the gap between the casing and the honeycomb heater, i.e. the by-pass flow, is minimized.

摘要： A multi-stage honeycomb heater includes: at least two honeycomb heaters electrically connected with each other and disposed along a stream of fluid; the two honeycomb heaters including furthest upstream honeycomb heater and a an adjacent honeycomb heater which is adjacent to and downstream of the furthest upstream honeycomb heater; each of the two honeycomb heaters having an electrically conductive honeycomb structure the honeycomb structure of the upstream honeycomb heater having slits for adjusting its electrical resistance and/or element for adjusting heat capacity of the honeycomb structure so that the ratio of applied power to heat capacity of the furthest upstream honeycomb heater is larger than the ratio of applied power to heat capacity of the adjacent honeycomb heater. Thus the upstream heater and the downstream heater can give similar temperature increases without a temperature distribution along a flow direction during the engine warm-up. A catalyst composition is coated on the partition walls of the honeycomb structure, and the light-off temperature of the catalyst composition of the upstream honeycomb heater is lower than that of the adjacent honeycomb heater.

摘要： A catalyst for exhaust gas purification has at least one monolith carrier, at least one first catalyst layer having a three-way catalytic activity, provided on the carrier, and a second catalyst layer having a hydrocarbon purification activity, provided on the first catalyst layer. In a gasoline engine automobile provided with the above catalyst for exhaust gas purification in the exhaust gas system, the hydrocarbons present in the exhaust gas can be converted at a high efficiency by introducing secondary air into the exhaust gas in front of the catalyst to make the exhaust gas lean, at the engine start when a large amount of unburnt hydrocarbons are present in the exhaust gas. Further, the engine warm-up property of the automobile can be improved by the heat generated by the catalytic reaction of the hydrocarbons. The catalyst further exhibits a three-way catalytic activity even during the steady state engine operation after warm-up.
