摘要： A device for reducing the emission of carbon particles from combustion of hydrocarbons, more particularly in exhaust emission of vehicles, includes a duality of electrically conducting rotating members with opposite polarities, charged with high voltage to create a corona discharge and agglomerate the ionized carbon particles. The carbon particles are cleaned using a plurality of wipers. The agglomerated carbon particles are then separated in a removable collection box or are optionally fed to a cyclone filter to be disposed. Various embodiments may be installed in existing vehicles as well as in open source pollution locations to helps control air pollution.

摘要： A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer-catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume damps spurious exhaust pressure excursions and removes particulates in the exhaust. The second volume houses an oxidation catalyst for treating exhaust to reduce exhaust emissions. The engine oil has at most 10 ppm zinc content to reduce metal poisons contained in the exhaust prior to contact with the oxidation catalyst. The engine oil preferably has a very low ash content to minimize sulfur combustion components in the exhaust to reduce masking of the oxidation catalyst. The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.

摘要： 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.

摘要： A method improves the operation of a diesel engine through the use of a fuel additive, a diesel particulate trap and a NO.sub.x -reducing catalyst. The operation of the NO.sub.x -reducing catalyst is enhanced by the introduction of urea or like compound upstream of the catalyst at temperatures effective for non-catalytic NO.sub.x reduction and the generation of ammonia. The additive comprises fuel-soluble compositions of platinum group metal in effective amounts to lower the emissions of unburned hydrocarbons and carbon monoxide from the trap. The catalytic activity provided to the exhaust system by the fuel additive is selective and preferably reduces the oxidation of SO.sub.2 to SO.sub.3. The platinum group metal compositions are preferably added in amounts effective to provide concentrations of the metal in the fuel of less than 1 part per million (ppm). Lithium and/or sodium compositions can be used in amounts effective to reduce the trap regeneration temperature, e.g. concentrations to provide about 1 to 100 ppm lithium metal, and/or 1 to 30 ppm sodium metal.

摘要： The invention relates to an exhaust gas purifier and a catalytic method of purifying exhaust gas, in which exhaust gas led into a combustion chamber (5) of the exhaust gas purifier, the exhaust gas is brought to centrifugal rotational motion, by which the exhaust gas flow is divided into a particle flow (9) and an actual gas flow (10). The particle flow (9) separated from the actual gas flow is retarded in relation to the actual gas flow (10). The direction of propagation of the particle flow is turned to be essentially opposite and the particle flow is rejoined to the actual gas flow and the rejoined exhaust gas flow is directed through a catalyst element (6).

摘要： This invention refers to a process for generation of an inert gas utilized for backsurging and artificial lift in oil wells, in which the flue gas, after the discharge of the diesel engine (1), is initially cooled and submitted to a state of separation of water and eventual solid particles, being thereafter admitted into the (reciprocating) compressors (8, 10) (amounting to 4 stages), in which it shall be compressed up to the working pressure (2,500 psi-nearly 172 atm), being thereafter cooled down to the working temperature (100.degree. F.-nearly 38.degree. C.), being then available for utilization. The skid-mounted system for inert gas generation of this invention includes, as well, a diesel engine (1) for discharge of the flue gas as from the Turbine of the Turbocompressor (3), cooling means (4, 7, 8, 11 and 12) for temperature reduction of the flue gas, means (5, 9) for separation of water and eventual solid particles from the flue gas, and means (6, 10) for compressing the flue gas.

摘要： An exhaust treatment system having a water scrubber, a centrifugal water trap for removing water droplets from exhaust flow and a filter for cleaning exhaust gases. The components are housed contiguously so that exhaust piping is not needed between the components. The water trap includes a frustoconical peripheral wall and a plurality of conduits having apertures for directing exhaust obliquely against the wall. The conduit apertures face in the same rotational direction to generate a rotational circulation of exhaust within the trap, which is entirely encircled by an annular filter. The water trap and filter are housed in a portion of the housing that is a low profile flat disc shaped to extend only a limited distance above the scrubber to which it is directly attached.
