Abstract
An exhaust particle cleaning device for a diesel engine includes a trap case provided in a passage way of exhaust gas. A filter material is disposed in the trap case so that carbon particles or other exhaust particles contained in the exhaust gas can be caught within the filter material during the time the exhaust gas is passed through the filter material. A plurality of electric heater elements are spread or dispersed on the upstream end face of the filter material, so that the exhaust gas passes through the areas defined between the plurality of heater elements. The electric heater element may be coated with a ceramic material.
