Abstract
Disclosed is a catalyzer heating device of an internal combustion engine. The glow plug is disposed in the catalyzer of the catalytic converter. The glow plug is operated when the temperature of the engine and the temperature of the catalyzer are relatively low so as to increase the temperature of the catalyzer for improving the exhaust gas purifying efficiency in the catalyzer.
