摘要： An arrangement for removing soot particles from the exhaust stream of a diesel internal combustion engine in such a manner that the soot particles are caught between conductor elements disposed at different potential, produce a short circuit and thereby burn off. In order to be able to realize a purification of the exhaust gas stream without a significant increase of the exhaust gas counterpressure, a centrifugal separator is connected to the exhaust gas line, which passes over into a soot particle collecting chamber constructed axially symmetrical to the longitudinal axis thereof; a predetermined number of electrodes is arranged in turn in the soot particle collecting chamber at a slight distance to the casing interior surface whereby the electrodes among one another or the electrodes and the soot particle collecting chamber itself are at a different potential.

摘要： An apparatus for removing solid particles from internal combustion engine exhaust gases is proposed, in which the flow of exhaust gas travels at a high speed of more than 2.5 m/sec through an elongated tube (4), in which a corona discharge takes place from a coaxial spray disk/electrode arrangement toward the wall of the tube. Inside the tube, the soot particles are agglomerated to form larger particles, which are not deposited on the walls because of the high flow speed, which then carries them to a centrifugal precipitator, leading away from which are a tube carrying scrubbed exhaust gas and an outlet having a small quantity of exhaust gas highly enriched with soot. This soot-enriched flow of exhaust gas can advantageously be recirculated to the intake side of the associated engine for afterburning.

摘要： A high-voltage insulator which is suitable for use in chambers carrying gas highly charged with solid particles and is used particularly in electrostatic filters used for cleaning an exhaust gas derived from internal combustion engines used to drive motor vehicles. The high-voltage insulator is columnar in structure, having shield-like ribs succeeding one another at intervals, adjacent to each of which in the insulator is one recess. With the remaining insulator parts having a smaller diameter, this recess forms a sharp edge, which defines discharge paths toward the flank of the shield-like ribs. Inside these paths, the insulator is kept free of soot coatings or conductive coatings, so that the insulator itself offers high resistance to leakage currents, which would cause insupportable power losses.

摘要： To remove solid particles such as soot, aerosols, and the like, from the exhaust gas of an internal combustion (IC) engine, for example a Diesel engine, the solid particles and aerosols are first charged in an electrostatic field which is generated between a solid surface (2), preferably cylindrical, and pointed discharge elements, typically electrostatic spray disks (3). The solid particles will adhere together, and to the surface, to form--with respect to the original dust and soot particles and aerosols, large area flakes and agglomerates which are carried along by the gas flow, and are then separated out in a mechanical separator (7, 15, ).

摘要： A pollution control device for reducing pollution of the atmosphere by automobile exhaust gases comprises a chamber in the exhaust line and at least one pair of electrode units installed in the chamber wall. Each pair of electrode units comprises two casings installed a short distance apart in the chamber wall, an insulator extending through each casing and an electrode wire extending through each insulator into the chamber. Inner ends of the electrode wires are bent and one of the insulators together with the respective wire is rotatable so that by such rotation the distance between the inner ends of the wire can be varied. High voltage current is supplied to the electrode wires and the rotatable insulator is controlled to bring the inner ends of the electrode wires close together to initiate a discharge when the engine is started and then increasing the gap to about one inch to provide a continuous flame which burns off carbon CO and any other combustible ingredients in the exhaust gases.

摘要： Apparatus for controlling particulate emissions from a combustion apparatus, such as a diesel engine. Diesel engine exhaust particles are electrically charged during the formation of the particles in the engine combustion chambers. A particle collector is used to collect the electrically charged particles on collecting structures connected to a high voltage power supply and ground. The collecting structures of the particle collector can be a plurality of parallel metal plates, spaced cylindrical rods, or concentrically located cylindrical members. A fibrous matrix can be located adjacent the particle collecting structure to collect the charged particles as they move through the matrix. In one embodiment, the collected particles separate from the collecting structures and return to the engine intake. In another embodiment, a removable collecting cartridge has electrically conductive plates for collecting the charged particles. The entire cartridge is removed for cleaning or replacement. The hot exhaust gas from the engine can be used to oxidize the collected particles. The collected particles that are not oxidized can be separated from the collecting structures and re-entrained into the gas. The re-entrained particles are larger than the particles formed in the combustion apparatus. The large particles can be removed by a downstream particle collection device.

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.
