<P>PROBLEM TO BE SOLVED: To provide an engine exhaust treatment apparatus which prevents an air supply source or a solenoid valve for air supply from being polluted with pollutant. <P>SOLUTION: A U-shaped pipe 42 is provided in the middle of an air supply passage 41 and when a combustible gas production equipment 1 does not produce combustible gas, the pollutant 43 such as residual fuel flowing into the air supply passage 41 from the combustible gas production equipment 1 by the pulsatory motion of the exhaust is stored in the U-shaped pipe 42. When the production of the combustible gas in the combustible gas production equipment 1 is restarted, the pollutant 43 stored in the U-shaped pipe 42 is purged toward the combustible gas production equipment 1 by air 25 from the air supply source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
