To provide a device for removing black smoke of exhaust emission from a diesel engine.
The present device is formed of a filter for trapping black smoke of exhaust emission from a diesel engine, a first nozzle for supplying at least fuel to the exhaust emission before it is fed to the filter, a catalytic combustion device interposed between the first nozzle and the filter for combusting the exhaust gas, a second nozzle 18 for supplying air/fuel mixture to a pre-combustion chamber 37 before supplying fuel from the first nozzle, an igniter 19 for igniting the mixture, a pre-combustion device 11 for turning and introducing a part of the exhaust gas for heating by increasing the temperature to a predetermined one, and the pre-combustion device 11 is provided with a damper chamber 35 as a device for preventing pulsation that prevents pulsation of the exhaust gas turned and introduced such that the exhaust gas passing through the pulsation preventing device is introduced from the area around the second nozzle 18 within the pre-combustion chamber 37.
