This patent describes an exhaust gas cleaning device for diesel engines. This cleaning device consists of: a filter provided in exhaust gas passage of the diesel engine for trapping particulate materials in exhaust gas which passes through. A burner upstream of the filter for burning the particulate materials deposited on the filter. The filter has a gas inlet surface means which is substantially perpendicular to an axial direction along which the exhaust gas is substantially passed and where the particulate materials are apt to be deposited. The burner includes a fuel nozzle and cylindrical combustion chamber for effecting combustion of fuel from the fuel nozzle. Engine exhaust gas introduction is positioned between the fuel nozzle and the filter. A mixing chamber is between the combustion chamber and the filter means for drawing the engine exhaust gas to mix it with combustion gas. The burner, the mixing chamber and the filter is arranged in a line, the mixing chamber has an inlet communicating with the combustion chamber and an outlet opposite to the inlet.
