  • Patent number: 11050223
    Abstract: The present disclosure relates to an alternating bipolar ionizer. It is a plate-type structure consisting of a substrate, an emitter plate, a dielectric barrier plate, and a ground plate. The ground plate and the emitter plate form an electric field, and the electrons of the emitter plate are led out of the dielectric barrier plate on a grounding side of the electric field. Some electrons meet the grounding pole plate and flow into the ground plate to form a current, and some escape from the surface of the dielectric barrier plate and meet the indoor air molecules. When the escaped electrons reach a certain rate, the oxygen molecules can be excited to be an ionic state, and air quality can improve. When AC high-voltage current is inputted, the bipolar ions are generated alternately, so a bipolar ionized gas flow can be injected into the air to improve air quality.

  • Patent number: 9021793
    Abstract: A vehicle includes an internal combustion engine operatively disposed therein. The engine generates exhaust gases. The vehicle further includes an alternator operatively connected to the engine. The alternator produces DC power. An ultracapacitor is operatively connected to the alternator to receive electrical energy therefrom. The vehicle still further includes an exhaust gas treatment system operatively connected to the engine to receive exhaust gases therefrom. The exhaust gas treatment system includes an electrically heated catalyst (EHC) device electrically connected to the ultracapacitor to selectively heat a catalytic exhaust system component. The ultracapacitor stores energy converted by the alternator from vehicle kinetic energy and releases the stored energy to heat the EHC.

  • Patent number: 8991153
    Abstract: A method and system for treating emissions includes charging particles in an exhaust stream, producing one or more radicals, and oxidizing at least a portion of the charged particles with at least a portion of the produced radicals. At least a portion of the charged particles in the exhaust stream are then attracted on at least one attraction surface which is one of oppositely charged from the charged particles and grounded. The attracted particles are oxidized with another portion of the one or more produced radicals to self regenerate the at least one attraction surface. Downstream from where the attracted particles are oxidized, at least a portion of one or more first compounds in the exhaust stream are converted to one or more second compounds downstream from the attracting. Additionally, at least a portion of any remaining charged particles are oxidized into one or more gases.

  • Patent number: 8959901
    Abstract: A metal-gas battery that utilizes an exhaust gas stream from a combustion engine as reactive gases is provided. Almost constant concentration of exhaust gases are supplied to the metal-gas battery via an existing engine systematic combustion system. The systematic combustion system keeps a definite air fuel mixture (A/F) that acts to enhance the fuel efficiency of the vehicle, and the metal-gas battery leverages the existing vehicle air management system. Exhaust heat of the exhaust gases is sometimes utilized for the heat control of the vehicle, and then the cooled exhaust gases are introduced into the metal-air battery to be consumed during a cathode reduction reaction to create and store electrical energy. The metal-gas battery supports the cleaning of exhausted gases using existing emission catalysts.

  • Publication number: 20150033708
    Abstract: A diesel engine exhaust treatment device includes an exhaust flow divider in an exhaust path. The flow divider causes exhaust to flow EGR gas with PM unevenly distributed and remaining discharged gas in a divided manner. EGR gas is recirculated to a combustion chamber, and the discharged gas is atmospherically discharged. First and second corona discharge passages are provided at the exhaust flow divider. Corona discharge in the first discharge passage causes the PM, water vapor, and oxygen in the exhaust to generate electron attachment. Electrostatic force causes the exhaust to flow the EGR gas with the electron-attached PM, water vapor, and oxygen unevenly distributed and the remaining discharged gas in a divided manner. The discharged gas is guided to the second discharge passage. Corona discharge in the second discharge passage causes gas molecules in the discharged gas to dissociate, and NOx in the discharged gas is reduced to nitrogen.
