Abstract

An exhaust infrared purifying device and method of a diesel engine are disclosed. The device includes a housing containing a cylinder body (33), filter meshes (34) and porous plates (35) are disposed at the both sides of the cylinder body (33) in a sequence of from inner to outer, and infrared spheres (36) are filled between both porous plates. The character of the device is that a buffer net (37) is disposed at the back of the porous plate (35) located at the inlet side, and at least a layer trap filter mesh (38) is provided in the cylinder body (33). The character of the method is that the inlet of the honeycomb heating purifier (3) is connected with the exhaust vent (101) and the outlet of the honeycomb heating purifier (3) is connected with the exhaust manifold (102). The deleterious pollution in the exhaust gas could be purified effectively.
