International Classification:

B01J 1908

US Classification:

204164, 204177, 42218604, 60275

Abstract:

An exhaust treatment system is provided for use with an internal combustion engine of a motor vehicle. The exhaust treatment system includes a parallel plate, monolithic plasma reactor for reducing nitrogen oxides in the exhaust gas from the engine, an electric power source for providing an electrical signal to the electrodes of the plasma reactor, and a controller interconnected between the electric power source and the plasma reactor for modulating the electrical signal to the plasma reactor. More specifically, the electric power source provides an alternating current electrical signal and the controller modulates the electrical signal off in accordance with a predetermined duty cycle, thereby achieving uniform barrier discharge in the plasma reactor.

International Classification:

B01J 1908

US Classification:

42218604, 60275, 204177

Abstract:

A system and method for treating a combustion exhaust stream includes admitting an exhaust stream into a non-thermal plasma reactor having at least one segmented non-thermal plasma element including a plurality of individually energizable electrode segments defining a plurality of corona volumes. In a preferred embodiment, the electrode segments are progressively smaller in size in the exhaust flow direction to provide optimum plasma volume variation. Individually energizable electrodes are selectively activated to effect variable corona volumes for treating an exhaust stream. Additional reactor segments are activated only as needed, such as during periods of high exhaust flow, for efficient treatment of the exhaust stream so as to maintain optimized high space velocity in the active corona volume. The segmented elements may comprise a variety of shapes. The system and method are particularly suitable for gas pretreatment and downstream diesel particulate filter regeneration.

International Classification:

F01N 3/00

US Classification:

60295, 60274, 60286, 60289, 60297, 60311

Abstract:

A diesel exhaust gas system includes a diesel particulate filter (DPF), a trap for nitrogen oxides (LNT), a hydrocarbon catalytic reformer for generating reformate, and an air supply. A method for controlling the rate of burn of soot in a DPF limits the oxygen percentage in the exhaust to about 6%. The LNT may be located ahead of the DPF in the exhaust line. Reformate is directed with exhaust through the LNT. The second flow of air cools the exhaust gas and thereby prevents overheating of the DPF substrate. The DPF also may be located ahead of the LNT. Reformate is controllably combusted by the second air flow in the DPF, reducing the oxygen percentage to about 6%, thus limiting the rate at which soot in the DPF can burn and thereby preventing overheating of the DPF substrate.

Abstract:

A method and system for introducing supplemental material to an exhaust aftertreatment device, including: a delivery system, an air pump operable to input pressurized air to the delivery system, and a turbosupercharger of an internal combustion engine operable to deliver pressurized air to an inlet of the air pump. The supplemental material introduced to the exhaust aftertreatment device is pressurized by the pressurized air input from the air pump, and the air inlet to the air pump is pressurized by the turbosupercharger for the internal combustion engine. The delivery system uses existing pressurized air generated within the engine system from the turbosupercharger to supplement air pressure supplied to the turbine-style air pump used by the delivery system. The supplemental material may comprise ammonia, hydrogen, carbon monoxide, or urea.
