| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission device capable of appropriately controlling the state of an exhaust emission catalyst by using a CO<SB>2</SB>absorbing/releasing means. <P>SOLUTION: The exhaust emission control device is equipped with: the exhaust emission control catalyst 6 provided in an exhaust passage 2 of an engine 1; a CO<SB>2</SB>absorbing/releasing member 5 for absorbing CO<SB>2</SB>in a first state and releasing CO<SB>2</SB>in a second state, provided on the further upstream side of the exhaust emission control catalyst 6 inside the exhaust passage 2; a heater 4 for changing CO<SB>2</SB>absorbing/releasing member 5 between the first and the second states; and an ECU 8 for operating the heater 4 so that the releasing amount of CO<SB>2</SB>from the absorbing/releasing member 5 is controlled according to the state of the exhaust emission control catalyst 6. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
