<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission cleaning system capable of solving a problem of jamming pressure takeoff piping by preventing unflammable fuel in exhaust gas from becoming like tar at an inlet part of the pressure takeoff piping. <P>SOLUTION: The exhaust emission cleaning system 1 provided with a diesel particulate filter 13 in an exhaust gas passage of an internal combustion engine, measures the pressure of exhaust gas of the diesel particulate filter 13 at the pressure takeoff piping 2. The pressure takeoff piping 2 is separated into opening side piping 2b and sensor side piping 2c near an opening 2a in the exhaust gas passage of the pressure takeoff piping 2, and the opening side piping 2b and the sensor side piping 2c are connected through a storage chamber 3 for storing a tar-like material F produced when the unflammable fuel in the exhaust gas is cooled. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
