Abstract
Apparatus for removing black fumes from exhaust gas from an internal combustion engine includes a filter mounted on an exhaust pipe of the engine. The filter includes a body defining a filter chamber and a filter element mounted within the filter chamber for collecting carbon particles constituting the black fume. A solution dispersing device is provided for dispersing a solution of catalyst to the exhaust gas in the filter chamber at a position upstream of the filter element to cause the oxidation of the carbon particles collected in the filter element to remove them therefrom. There is also disclosed a method of removing black fume from exhaust gas from the internal combustion engine.
