INTEGRATED UNDERFLOOR CATALYTIC CONVERTER ASSEMBLY

摘要

An integrated under-floor catalytic converter assembly is provided to exhibit optimum catalytic filtering performance by adjusting the filtering ratio of the first and second catalytic converters depending on the amount of pollutant. An integrated under-floor catalytic converter assembly comprises first and second catalytic converters(110,120) including catalyst to reduce the contaminant of the exhaust gas, and a flow guide(130) interconnecting the first and the second catalytic converter. The amount of catalyst included in the catalytic converter is regulated according to the contamination degree of exhaust gas, and the length of the flow guide is adjusted according to the condition of installation space.
