CURRENT FLOW CONTROL SYSTEM FOR USE IN CATALYST DEVICE HEATED BY CURRENT FLOW

摘要

PROBLEM TO BE SOLVED: To provide an current flow control system for use in a catalyst device heated by current flow capable of preventing the damaging of its catalyst support.;SOLUTION: The current flow control system for use in a catalyst device 17 heated by current flow is equipped with a catalyst device 17 heated by current flow comprising a catalyst support 17a that heats a supported catalyst by its temperature rise caused by its current flow and has a NTC characteristic of changing its current flow resistance in accordance with its temperature change, first and second temperature sensors 18a, 18b disposed on the catalyst support 17a, and a controller 5 that controls the current flow of the catalyst support 17a from the information coming from the first and the second temperature sensors 18a, 18b.;COPYRIGHT: (C)2009,JPO&INPIT
