Filed: 1995-05-29
Abstract: PURPOSE: To heat an exhaust emission control catalyzer in time of starting an automobile engine to an active temperature in a moment as well as to solve a problem on temperature unevenness even in time of exhaust gas flowing. CONSTITUTION: A current-energizing layer 3 constituting of conductive material is installed in both ends of a honeycomb base 2 consisting of a nonconductive material and a central part of this honeycomb base 2 being interconnected to these ends. When a current is made to flow into this current-energizing layer 3, it is heated, thereby raising the temperature of a catalyzer carried by this layer 3 to the extent of an active temperature so well. In addition, the central part, where a flowing quantity of exhaust gas is abundant and a heat exchange is intense is sufficiently heated by the energizing layer 3, but a peripheral part, where a flow of exhaust gas is slow and not cooled so much, is merely heated by means of heat conduction alone from the central part, so consequently a temperature distribution of the whole catalyzer, namely, a catalyzer capacity is uniformized in this way.
