    摘要: A moisture removal device for an internal combustion engine use exhaust gas purifying device with a trapped moisture amount estimation means which estimates amount of moisture exhausted from an internal combustion engine and trapped in the catalyst, a judgement means which judges whether the estimated value of the trapped moisture amount exceeds a predetermined amount, and means for controlling removal of the moisture trapped in the catalyst, wherein when the estimated value of moisture trapped in the catalyst exceeds the predetermined value, a control of removing the moisture in the catalyst is performed. Whereby, since the moisture trapped by the catalyst can be removed and a possible elution of the catalyst components can be prevented, reduction of exhaust gas purifying performance of the catalyst can be prevented.
