Abstract

PURPOSE:To prevent the heat deterioration of the catalyzer by forming the rotary shaft attached to the auxiliary catalyzer so that it is operated in response to the temperature of the main oxidized catalyzer in the exhaust gas purifier wherein when the exhaust gas may be at a low temperature, it is contaminated by the auxiliary catalyzer, and thereafter, it is introduced to the main oxidized catalyzer.
