<p><P>PROBLEM TO BE SOLVED: To provide a device for treating exhaust gas from a diesel engine, which burns combustible gas using oxygen in the exhaust gas, even in cooler exhaust gas. <P>SOLUTION: Combustible gas 4 and secondary air 48 are supplied to a secondary air mixing chamber 44 from a combustible gas generation catalyst chamber 11 and a secondary air supply source 47. Then, the combustible gas 4 and secondary gas 48 are mixed in the secondary air mixing chamber 44 into secondary air mixing gas 49. When the secondary air mixing gas 49 passes through combustion catalyst 46, part of the combustible gas 4 is burned with the secondary air as catalytic combustion. The temperature of rest of the combustible gas 4 passing through the combustion catalyst 46 is raised by the combustion heat. The combustible gas 4 with raised temperature is discharged to an exhaust gas passage 7 from a combustible gas injection hole 6. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
