Abstract

A device for removing fine carbon particles from exhaust gas emitted by automobile diesel engines or the like thereby to clean the exhaust gas. The device incorporates a filter for collecting fine carbon particles suspended by the exhaust gas. After a predetermined amount of fine carbon particles is accumulated on the filter, the carbon particles are burnt to regenerate the filter. The detection of amount of carbon particles accumulated on the filter is made through the detection of the fuel consumption of the engine or the differential pressure across the filter.
