An apparatus is described for the removal of solid components from the exhaust gas of internal combustion engines, in particular for the removal of soot components from the exhaust gases of self-igniting combustion engines. Under the influence of electrostatic fields, the solid components are diverted and carried to a fresh-air current flowing toward the intake side of the engine. This recirculation of the solid components may be effected either by means of the recirculation of a partial flow of the exhaust gas which has been enriched with solid components, in which case the solid components are deflected into this partial flow in an electrostatic field, or these solid components may be guided into the fresh-air current aspirated by the engine, in this case with the cooperation of a mechanical transport means and electrostatic bonding forces.

1. An apparatus for the removal of solid components from an exhaust gas system of an internal combustion engine, comprising an intake system, a spiral housing, a connecting line connecting said exhaust gas system with said spiral housing to provide an inlet for said apparatus, a tubular housing having an axial center, a circumferential wall and end portions, said tubular housing being connected to said spiral housing, a first electrode extending longitudinally along said axial center of said housing and insulated therefrom, a perforated second electrode surrounding said first electrode, a first annular chamber between said wall and said second electrode within said tubular housing, at least one exhaust recirculation line extending from said first annular chamber to said intake system of said engine to provide one outlet, a second annular chamber disposed between said electrodes, said second annular chamber being connected with said spiral housing to receive exhaust gases discharged from said exhaust gas system, said spiral housing discharging tangentially into said second annular chamber, and a discharge line leading tangentially from said second annular chamber back to said exhaust system to provide a second outlet. 2. An apparatus as defined by claim 1, characterized in that said first electrode comprises a perforated tube having a free end which is associated with an insulated tube, said insulated tube being connected via an exhaust recirculation line and of said at least one exhaust recirculation line with said intake side of said engine. 3. An apparatus as defined by claim 2, characterized in that said housing has an exhaust gas inlet and ionizing electrodes are provided in close proximity thereto. 4. An apparatus as defined by claim 1, characterized in that said connecting line discharges into said housing medially of the length thereof and further that in proximity to said end portions of said housing first and second discharge lines lead away from said second annular chamber and that said first annular chamber is divided by an inlet location of said connecting line into a first partial chamber and a second partial chamber, a second exhaust gas recirculation line and a third exhaust gas recirculation line of said at least one exhaust recirculation line leading away from the respective outermost ends of the partial chambers.
