<p><P>PROBLEM TO BE SOLVED: To provide an EGR filter device capable of burning and removing particulates accumulating on a filter with temperature of exhaust gas, and having strength against high pressure of exhaust gas, small pressure loss and high collection efficiency. <P>SOLUTION: This EGR filter device has a filter removing particulates in EGR gas recirculated to an intake side of the engine from part of exhaust gas exhausted from the engine built therein. An output port of the EGR gas is provided on an exhaust manifold connected to the engine. The filter has thickness 5-50 mm, porosity 88-98% and compression strength 0.4 MPa or greater. An exhaust gas flow in side end surface of the filter exists at a position 20 mm at maximum in a flow direction of EGR gas from an inner surface of the exhaust manifold. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
