A carbon particulates cleaning device comprises a casing, a filter for catching and collecting carbon particulates included in the exhaust gas within the casing, an oxidizing catalyst carrier which is disposed within the casing and a fuel supply means for supplying the fuel into the interior of the casing. When the volume of the carbon particulates caught and collected by the filter reaches a predetermined volume, the fuel is supplied from the fuel supply means into the interior of the casing and burnt by the oxidization promoting action of the oxidizing catalyst. And the caught and collected carbon particulates are burnt and cleaned due to the burning heat of the fuel.
