Claims

[Scope of Claim for Utility Model Registration] (1) An exhaust path for leading exhaust gas from an internal combustion engine to the outside; a filter made of refractory ceramic that captures unburned particles; and a filter for preheating that is installed in the exhaust passage in close proximity to the filter on the upstream side of the exhaust gas and sends the exhaust gas through the filter. The heater for preheating is formed in a straight line with an electric resistance wire so as to have a dimension shorter than the radius of the exhaust passage, and the heater for preheating is formed in a straight line so as to have a dimension shorter than the radius of the exhaust passage, and the heater is provided with an angle of 15 to 45 degrees in the radial direction on the outer periphery of the exhaust passage. 1. An exhaust gas reburning device for an internal combustion engine, etc., characterized in that a plurality of devices are arranged so as to form an angle and are located on the same plane with each other, and are energized as appropriate during operation. (2) The exhaust gas reburning device for an internal combustion engine or the like as set forth in claim 1, wherein the filter is formed of honeycomb-shaped ceramic. (3) The exhaust gas reburning device for an internal combustion engine or the like as set forth in claim 1, wherein the preheating heater is a glow plug type sheathed heater. (4) The exhaust gas reburning device for an internal combustion engine or the like according to claim 3, wherein the sheathed heater is supported by a ring-shaped frame. (5) The re-combustion of exhaust gas from an internal combustion engine or the like as set forth in claim 1 of the utility model registration claim, characterized in that the preheating heater has four or more electrical resistors arranged at equal angular intervals. Device.
