<p>PROBLEM TO BE SOLVED: To provide a device for removing black smoke of exhaust emission from a diesel engine. SOLUTION: 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 a flame reducing plate 46 for shielding the tip of the flame within the pre-combustion chamber 37.</p> |
