<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device giving no load to a power supply device for an ozone generation device. <P>SOLUTION: A pipe 4 and an air port 7 are each connected to the ozone generation device 5 at its opposite side to electrodes 8, 8, namely, so that electrodes 8, 8 are located between the pipe 4 and the air port 7. A inner diameter d<SB>1</SB>of the air port 7 at its connection portion to the ozone generation device 5 is smaller than an inner diameter d<SB>2</SB>of the pipe 4 at its connection portion to the ozone generation device 5. Thus, the opening area of the air port 7 at its connection portion to the ozone generation device 5 is smaller than the opening area of the pipe 4 at its connection portion to the ozone generation device 5. In the air port 7, a filter 12 is provided for removing dust from air introduced into the ozone generation device 5. <P>COPYRIGHT: (C)2011,JPO&INPIT |
