<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device for a vehicle capable of preventing flow-out of nitrogen oxides to a downstream side of a reducing catalyst from the starting time of an internal combustion engine without wasting power of a battery and capable of shortening the start waiting time of the internal combustion engine when starting the internal combustion engine under a low-temperature environment. <P>SOLUTION: This exhaust emission control device for a vehicle includes the reducing catalyst arranged in an exhaust passage of the internal combustion engine of the vehicle, a reducing agent supply means capable of supplying a reducing agent into the exhaust passage on an upstream side of the reducing catalyst, and a storage tank storing the reducing agent, and deoxidizes nitrogen oxide included in the exhaust gas by bringing the reducing agent supplied from the reducing agent supply means and the exhaust gas of the internal combustion engine into contact with the reducing catalyst. This exhaust emission control device also includes: a heating means capable of heating the exhaust emission control device by feeding power; and a power feeding means including a connection part to be connected to an external power source outside the vehicle so as to supply power from the external power source to the heating means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
