ABSTRACT:
An exhaust gas cleaning device for diesel engines including a filter provided in an exhaust gas passage of the diesel engine for trapping particulate materials in exhaust gas passing through the exhaust gas passage, and a burner upstream of the filter for burning the particulate materials deposited on the filter. The filter has a gas inlet surface which is perpendicular to an axial direction along which the exhaust gas is passed and where the particulate materials are apt to be deposited. The burner include a fuel nozzle and a combustion chamber for effecting combustion of fuel from the fuel nozzle. A mixing chamber is provided between the combustion chamber and the filter for drawing the engine exhaust gas to mix it with combustion gas from the combustion chamber. The mixing chamber has an inlet communicating with the combustion chamber and an outlet opposite to the inlet. The gas inlet surface of the filter is exposed to the mixing chamber at the outlet.
