The electric dust collecting apparatus comprises a plurality of discharge electrodes that are disposed in an exhaust flow passage, a ground electrode that constitutes at least a part of an inner wall surface of the exhaust flow passage, and a voltage applying device that is configured to apply voltage selectively from a common power supply to each of the plurality of discharge electrodes. The plurality of discharge regions, each of which includes at least one discharge electrode, are provided in the exhaust flow passage and an electrode-to-electrode distance between the discharge electrode and the ground electrode is different in each of the plurality of discharge regions. The voltage applying device applies voltage to the discharge electrode for each discharge region, and changes the discharge region where voltage is applied to the discharge electrode in accordance with exhaust gas temperature.

An improved electrocatalytic system utilizes an Organic Rankine cycle system to take advantage of exhaust fume heat to convert a working fluid to steam used in a steam expander to generate electricity. The generated electricity is then used in electrolyzing water to produce hydrogen gases used as a supplemental fuel in an internal combustion (IC) engine. Thereby, the improved electrocatalytic system provides an efficient, less costly and retrofittable system for reducing harmful emissions and fossil fuel consumption in vehicles.

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.

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.

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).

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.

A device for treating exhaust gas containing soot particles includes at least one ionization element for ionizing soot particles, at least one filter element having at least one section to which an electric potential can be applied and at least one agglomeration unit for at least partial agglomeration of electrically charged soot particles. The agglomeration unit is disposed between the ionization element and the filter element and the agglomeration unit has at least one outer pipe and at least one inner element. The filtering power of an exhaust system of an internal combustion engine is therefore increased by an increase in the agglomeration rate of the soot particles. A motor vehicle having the device is also provided.
