<p>PROBLEM TO BE SOLVED: To provide a particulate filter capable of burning the exhaust gas over all without damaging a filter part by uniformly and fully heating the exhaust gas passed the heated part and avoiding a local heating. SOLUTION: The exhaust gas flowed from an inlet pipe 6a is heated with heaters 2a to 2d. The heated exhaust gas is decelerated/changed in a direction and mixed by repeating collision with a first gas colliding body 13 to a third gas colliding body 15 successively. The collision is accelerated by the displacement of each communicating pole 13A to 15A of each gas colliding body 13 to 15. As the result, the exhaust gas is homogenized in temperature over all, then the PM can be burned for the filter part 4. The filter part 4 is prevented from damaging owing to directly entering from the heating body into the filter part 4, locally burning and reaching a high temperature.</p> |
