Abstract
PURPOSE: To accelerate the activation of an exhaust gas purifying catalyst at the time of cold starting and directly detect the activity of the catalyst through various lamps, by providing a heater in the catalyst.
CONSTITUTION: The heater 10 for heating the catalyst and a temperature sensor 12 are provided in a catalyst converter 9 installed at the exhaust pipe of an internal combustion engine. The heater 10 is connected to a power relay 8, a computer 11 consisting of identidication circuits S1, S2 and a NOR circuit, and contacts (a), (b). When the temperature of the catalyst 9 is lower than a predetermined level, the heater 10 is energized. Red, blue and yellow lamps 13, 14, 15 are connected to the computer 11 to indicate the degree of heating of the catalyst when the heater 10 is energized.
