<p><P>PROBLEM TO BE SOLVED: To avoid obstacles of maintenance work caused by electricity remaining in a processing means in a device for processing exhaust emission utilizing high voltage. <P>SOLUTION: An earthed circuit 30 is energized by switches 31, 33 for earthing a high voltage side of a reactor 10 under predetermined conditions that an engine is stopped, etc. Even shortly after processing operation of the reactor 10, the reactor 10 can be previously made to discharge before the maintenance work, etc. Thereby, the obstacles of the maintenance work caused by the remaining electricity in the reactor 10 can be avoided. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
