Abstract

PURPOSE:To monitor the temperature of catalysts with a simple constitution by detecting the operating temperature of an exhaust gas purifier for engines with a thermocouple, and displaying the same on an indicating meter by dividing to a low temperature inactive region, a normal temperature region and a high temperature abnormal region.
