    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.

    摘要翻译： 本发明的目的是根据排气空燃比适当地控制电晕放电的状态，并且有效地净化废气中的颗粒物质（PM）。 发动机配备有电晕放电型废气排放控制装置。 废气排放控制装置通过在中心电极和接地电极之间产生电晕放电来净化废气中的PM。 当空燃比处于浓区域时，ECU控制施加在电极之间的施加电压。 从而可以在防止电弧放电的同时获得最大的PM净化率。 当空燃比处于稀薄区域时，控制在电极之间流动的放电电流。 由此，能够抑制由废气中的PM量的降低引起的PM净化率的降低的同时抑制功率消耗。

    摘要： A concentration of HC in an exhaust gas is estimated with a high degree of accuracy by making use of a particulate matter processing apparatus (1). In the particulate matter processing apparatus (1) in which a processing part (3) with an electrode (5) installed therein is arranged in an exhaust passage (2) of an internal combustion engine, wherein particulate matter is caused to aggregate by generating a potential difference between the electrode (5) and the processing part (3), provision is made for a power supply (6) that is connected to the electrode (5) and applies a voltage thereto, an insulation part (4) that insulates electricity between the processing part (3) and the exhaust passage (2), and a ground part (53) that grounds the processing part (3), a detection device (9) that detects an electric current in the ground part (53), and an estimation device (7) that estimates a concentration of HC in an exhaust gas based on the electric current detected by the detection device (9) at the time when the voltage is applied to the electrode (5) by means of the power supply (6).

    摘要： Technologies are presented for applying electrical energy to a combustion reaction to produce agglomerated combustion particulates. For example, a system may include: one or more electrodes configured to apply electrical energy to a combustion reaction; a combustion zone configured to support the combustion reaction of a fuel at a fuel source; and an electrical power source operatively coupled to the one or more electrodes and configured to apply electrical energy to the combustion reaction. The combustion reaction is controlled to produce a distribution of agglomerated combustion particulates characterized by an increase in at least one of an average particulate diameter or an average particulate mass.
