Patent ID: 7549286

Claim:
An exhaust emission control device comprising: first and second dispersion plates, each including a plurality of communicating holes, said dispersion plates arranged in a filter casing incorporated in an exhaust pipe such that the plates are opposed to each other in a direction of flow of exhaust gas, a catalytic regenerative particulate filter being received in a reception chamber defined by and between the first and second dispersion plates, a temperature sensor fitted to the filter casing so as to detect exhaust temperature in the reception chamber, and a sensing element of the temperature sensor positioned to be in a flow of the exhaust gas, wherein the first dispersion plate is disposed on a first side of the particulate filter closer to an inlet than is the second dispersion plate, wherein the second dispersion plate is disposed on a second side of the particulate filter opposite the first side, and wherein the sensing element is disposed between the first dispersion plate and the particulate filter, and directly behind one of the communicating holes in the first dispersion plate, or between the second dispersion plate and the particulate filter, and directly in front of one of the communicating holes in the second dispersion plate.
