ELECTRIC HEATING TYPE CATALYTIC DEVICE FOR CONTROLLING EXHAUST EMISSION

摘要

PURPOSE:To improve the heat transfer to a non-heating part of a catalyst carrier, and facilitate the activation of the catalyst at the non-heating part. CONSTITUTION:In an electric heating type catalytic device for controlling the exhaust emission which is formed of the electrically conductive material, and provided with a catalytic carrier 2 where heating parts 3 are locally formed, an exhaust gas flow deflecting means to deflect the exhaust. gas from the heating parts 3 to a non-heating part such as louvres 6a, 6b is provided inside the catalytic carrier 2.
