ABSTRACT:
A carbon particulates cleaning device for use in a diesel engine of an automobile or the like comprises an exhaust gas main pipe, an exhaust gas branch pipe diverged from the exhaust main pipe, a carbon particulates catching member which is provided within at least one of the exhaust gas main pipe and the exhaust gas branch pipe, a valve means by which exhaust gas is selectively supplied into the exhaust gas main pipe or the exhaust gas branch pipe, a heating means which heats the carbon particulates catching member, a gas supplying means which supplies gas into the carbon particulates catching member when the carbon particulates catching member is heated and a control means which controls each operation of the valve means, the heating means and the gas supplying means. When the carbon particulates caught by the carbon particulates catching member reaches a predetermined volume, a control means operates to stop the exhaust gas from flowing into the carbon particulates catching member, the upper stream portion of the carbon particulates catching member is heated over the burning temperature of carbon particulates by the heating means and gas such as air is supplied from the gas supplying means into the carbon particulates catching member to transmit the heat of the upper stream portion of the carbon particulates catching member into the downstream portion thereof. As a result, the carbon particulates catching member is effectively heated by a small amount of heat energy and the carbon particulates caught by the carbon particulates catching member are burnt and eliminated.
