摘要： A diesel particulate filter system for treating the exhaust gas of a diesel engine which is small in size and inexpensive. The system includes a particulate filter connected in a gas line from the engine, a burner, including an ignition plug, connected at a point upstream of the particulate filter and which is supplied with fuel, a primary air flow for atomizing the fuel, and a secondary air flow for burning the particulates trapped in the particular filter and which supplies the particulate filter with a hot burning gas produced by the ignition plug. Primary and secondary pumps supply, respectively, the primary and secondary air flows. A single motor drives both the primary and secondary air pumps. The ignition plug and motor are controlled so that when the amount of particulates trapped in the filter exceeds a preset level, the ignition plug and motor are activated to clean the filter by burning the particulates in the burner.

摘要： An apparatus for controlling the supply of air to a burner used to recombust diesel particulates trapped in a ceramic filter. The inventive control apparatus includes an exhaust bypass line that bypasses the filter, an air supply line leading to a burner associated with the filter, a flow control valve that adjusts the cross-sectional area for the air flow in the air supply line, a relief valve that maintains a constant difference between pressures at points upstream and downstream of the flow control valve, and a control unit that controls the degree of opening of the flow control valve. With the invention, precise control over the flow rate of secondary air is ensured.

摘要： A particulate removing device comprises a regenerating burner connected via an interrupting valve to a mixer subsequently connected to a particulate filter. The interrupting valve may be disposed in a housing for the burner on that end portion connected to the mixer through an exit to open and close the exit. When the burner generates a combustion gas, the valve opens the exit to permit the combustion gas to enter the mixer where it is mixed with an exhaust gas from a Diesel engine. The mixed gas heats and regenerates the particulate filter. When the burner is not used, the valve closes the exit to prevent the exhaust gas from the mixer from partly entering the burners housing. Alternatively, the interrupting valve may be disposed in a housing for the mixer on that end portion connected to the burner's housing through an exit to open and close the inlet.
