摘要： Systems, methods, and apparatus are contemplated in which a tube cell that produces a dielectric barrier discharge (DBD) is individually configured to minimize the mixing of unwanted byproducts of the generated plasma with an exhaust air stream. The tube cell generates a DBD within a tube cell, such that oxidants or radicals are generated in an environment substantially separated from the exhaust stream. The generated oxidants are directed to intersect with the exhaust stream to minimize the generation of unwanted byproducts. The tube cells are further shaped and arranged in tube cell arrays to alter the flow dynamics of the exhaust stream and the oxidant or radical streams, including mixing of the streams.

摘要： Methods and systems are provided for addressing engine cold-start emissions while an exhaust catalyst is activated. In one example, a method for improving exhaust emissions may include flowing ionized air into an engine exhaust, downstream of an exhaust catalyst, to oxidize exhaust emissions left untreated by the catalyst. The approach reduces the PM load of the exhaust as well as of a downstream particulate matter filter.

摘要： A method of treating an exhaust gas produced by a vehicle internal combustion engine includes conveying the gas through a first reactor including a non-thermal plasma. The gas includes nitric oxide and is transitionable between a first condition in which the gas has a cold-start temperature that is less than or equal to about 150° C., and a second condition in which the gas has an operating temperature that is greater than about 150° C. During the first condition, the method includes contacting the gas and plasma to oxidize the nitric oxide to nitrogen dioxide and form an effluent that includes nitrogen dioxide. The method includes concurrently conveying the effluent through a second reactor including a diesel oxidation catalyst, and storing the nitrogen dioxide within the second reactor during only the first condition. The method includes, after storing, releasing nitrogen dioxide from the second reactor during only the second condition.

摘要： A gas treatment device includes an electric discharger, an electromagnetic wave oscillator, an antenna, and a fan. The electric discharger ionizes gas in a target space. The electromagnetic wave oscillator oscillates an electromagnetic wave to be radiated to the target space. The electromagnetic wave is radiated by the antenna toward a gas ionization region in which gas ionized by the electric discharger is provided. The electric discharger ionizes gas and the antenna radiates the electromagnetic wave thereto to generate plasma. The fan moves at least a part of the electric discharger, thereby changing a location of the gas ionization region, thereby moving the location of the plasma.

摘要： An object of this invention is to appropriately control the state of a corona discharge in accordance with an exhaust air-fuel ratio, and always purify particulate matter (PM) in exhaust gas efficiently. An engine is equipped with a corona discharge-type exhaust emission control device. The exhaust emission control device purifies PM in exhaust gas by generating a corona discharge between a center electrode and an earth electrode. When the air-fuel ratio is in a rich region, an ECU controls an applied voltage that is applied between the electrodes. It is thereby possible to obtain a maximum PM purification rate while preventing an arc discharge. When the air-fuel ratio is in a lean region, a discharge current flowing between the electrodes is controlled. It is thereby possible to suppress power consumption while compensating for a decrease in the PM purification rate caused by a reduction in the PM amount in the exhaust gas.

摘要： An exhaust system for treating an exhaust gas composition having NO2 in a first NO2 concentration. The exhaust system includes a first catalyst that contacts a first portion of the exhaust gas composition converting it into a first oxidized exhaust mixture that includes NO2 in a second NO2 concentration that is greater than the first NO2 concentration. The system further includes a bypass that receives a second portion of the exhaust gas composition and a recombination section positioned downstream of the first catalyst. The first oxidized exhaust mixture is combined with the second portion of the exhaust gas composition to produce a first combined exhaust gas mixture. A second catalyst converts the first combined exhaust gas mixture to a second combined exhaust gas mixture having a third NO2 concentration that is less than the second NO2 concentration. The method used by the exhaust system is also provided.
