ABSTRACT:
A carbon particulates cleaning device for collecting carbon particulates in exhaust gases discharged from an internal combustion engine and burning off the collected carbon particulates, is disclosed. The carbon particulates cleaning device comprises a heat resistant filter member, an electric heater which is provided on the upstream end surface of the filter member for regenerating the filter member, and an electric power source for supplying electric current to the electric heater. The electric heater is composed of at least two kinds of heating resistors, each of which applies different electric power to a unit area of the upstream end surface of the filter member. At the filter member regenerating time, electric current is supplied to the heating resistors successively in the order of from one providing the maximum electric power density to one providing the minimum electric power density.
