摘要:
The invention concerns a device comprising at least a plurality of ionizing corona-effect electrostatic precipitators including emissive and collecting electrodes. The number of electrostatic precipitators is defined on the basis of a flux to be treated, considering that the slower the passage, the more efficient the collection is, and the less the electrodes converted into resistors are cooled by the flux. The collecting electrodes, which are smooth and tubular, are alternately collectors and electric resistor, and therefor they are heated over short periods, at a temperature sufficient for incinerating or burning the collected particles. The emissive electrodes are centered in the collecting structures. Said electrodes are axial relative to the direction of the passage of the flux to be treated in the collecting electrodes and can be complementary to other electrodes in the form of beams perpendicular to the direction of the flux, gases and mists to be treated. Other devices can be associated therewith, such as oxidation catalysts, pre-filters, after filters or other devices enabling reduction of gaseous, solid and liquid pollutants and noise attenuation. The inventive device is designed, but not exclusively, for filtering and regenerating engine exhaust gases, oil and water mists, fumes, intake air, extraction or recycling, and generally all pollutants harmful to the environment.
摘要:
The present invention provides systems and methods to improve the performance and emission control of internal combustion engines equipped with nitrogen oxides storage-reduction ("NSR") emission control systems (206). The system comprises a NSR catalyst (206), a fuel processor (200) located upstream of the NSR catalyst, and at least one fuel injection port (208). The fuel processor (200) converts a fuel into a reducing gas mixture comprising CO and H2. The reducing gas mixture is then fed into the NSR catalyst (206), where it regenerates the NSR adsorbent, reduces the NOx to nitrogen, and optionally periodically desulfates the NSR catalyst. The fuel processor (200) comprises one or more catalysts, which facilitate reactions such as combustion, partial oxidation, and/or reforming and help consume excess oxygen present in an engine exhaust stream. The methods of the present invention provide for NSR catalyst adsorbent regeneration. Control strategies are provided to control the system and methods of the invention.

摘要:
PURPOSE: An exhaust manifold for improving the purification efficiency and life span of a catalytic converter is provided to improve the purification efficiency of a catalyst and to lengthen the life span of the catalyst by uniformly distributing exhaust gas to the sectional area of the catalyst. CONSTITUTION: A diffuser(10) of which diameter is increased downward is formed in the lower end of a mixing chamber(2). A catalytic converter(11) is connected to the diffuser. The exhaust gas emitted from each cylinder flows into the mixing chamber through corresponding runners(3-6). The exhaust gas swirls in the mixing chamber and is mixed uniformly. According to the structure of the diffuser, flow velocity is increased. Thus, the exhaust gas is distributed uniformly to the whole section of a catalyst of the catalytic converter.
