Definitions

  • This invention relates to ozone generators for internal combustion engines wherein the general requirements for ideal combustion are complete vaporization of the fuel, a constant supply of air in sufficient quantities, and efficient mixing of the fuel and air to support combustion.
  • An ozone generator for petrol operated internal combustion engines contains a cylindrical electrode (1) with perforations (2) and an internal electrode (3) with sawtooth edges. (4).
  • the electrodes are made of steel and Tungsten, Molybdenum or Chromium, or Steel coated with an oxide film, all of which possess a high electrical resistance.
  • the internal electrode (3) is located coaxially within the cylindrical electrode (1) and the two electrodes are supported and positioned between two ceramic discs (6) and (7). Screws (12) clamp the ceramic discs to the internal electrode.
  • the ceramic discs have a series of holes (7a) incorporated in their construction. These holes allow air to flow through the ozone generator when it is in operation.
  • the cylindrical electrode has synthetic rubber ozone resistant insulators (5) fitted at each end.
  • a coil spring (8) which serves both as a packing spring and earth is connected to the internal electrode (3) via the screw (13).
  • the electrodes and ceramic discs assembly are retained within a light alloy barrel half casting (14) by three screws (18) which passes through the wall of the casting and act as a Butt stops behind the ceramic disc (6).
  • An ozone outlet orifice (19) is drilled in the centre of the barrel half bowl into which is screwed an ozone outlet adaptor (9) comprising a ball valve (10), and ball valve housing (11). The ball is closed when the ozone generator is inoperative.
  • the high voltage necessary to establish and maintain the corona discharge is supplied by a transistorized circuit incorporating a primary coil (16) and a secondary coil (17) fig 2.
  • the complete circuit is sealed within a second light alloy barrel half casting (15).
  • the sealant is an ozone resistant silicon compound.
  • a power supply lead-not shown passes through a hole drilled in the barrel half casting, and an earthing screw (20) is located in the centre of the casting bowl.
  • Three air holes (21) are drilled immediatly behind the joint flange of the barrel half casting (15), and these are covered by filter packs supported in the thin gauge metal filter housing (22). The filter housings are secured by the screws (13) used to clamp the two barrel halves together. Lugs formed integral with the barrel half castings form the mounting (28) for the ozone generator.
  • a venturi adaptor (25) is positioned in the engine intake manifold immediatly downstream of the carburettor (27), and an ozone resistant hose (24) connects the ozone outlet adaptor (9) to the venturi adaptor pipe (26).
  • the power supply lead to the ozone generator is connected to an electri cal power source that is activated when the ignition is switched on.
  • the vacuum created in the engine intake manifold creates a pressure differential between the air holes (21) and the ozone outlet adaptor (9).
  • the differential pressure causes the ball valve (10) to open and air is induced to flow into the ozone generator.
  • the air flows in at the air holes (21), throtigh the holes (7a) in the ceramic discs and into the electric field between the cylindrical electrode (1 ) and the internal electrode (3).
  • the high voltage applied to the cylindrical electrode (1) arcs across to the internal electrode (3) where the sawteeth (4) create irregular distribution of the electric field between the two electrodes so as to generate a streamer corona discharge.
  • the perforations (2) in the cylindrical electrodes (1) help to stabilize the corona discharge, reduce the capacitance between the electrodes, prevent short circuit discharge, and surpress saturation caused by the discharge of secondary electrons.

Abstract

Dans un générateur d'ozone pour moteurs à essence à combustion interne, de grandes quantités d'ozone sont produites à partir de l'air qui est ionisé par l'action conjointe d'une décharge par effet corona auto-entretenu à l'intérieur d'un champ électrique produit entre une électrode cylindrique (1) et une électrode interne (3) montée à l'intérieur d'un demi-boîtier moulé cylindrique en alliage léger (14). Les deux électrodes sont montées coaxialement entre deux disques en céramique (6 et 7) qui supportent et positionnent les électrodes à l'intérieur du demi-boîtier cylindrique. Celui-ci possède un orifice de sortie d'ozone perçé dans le centre de l'extrémité fermée dans laquelle est vissé un adaptateur de sortie d'ozone (9). La tension élevée nécessaire pour la production du champ électrique entre les électrodes est produite par un circuit électrique à transistors incorporant une bobine primaire (16) et une bobine secondaire (17), logées à l'intérieur d'un deuxième demi-boîtier cylindrique en alliage léger (15). Ce demi-boîtier incorpore des trous d'air au travers desquels on induit l'écoulement d'air lorsque le générateur d'ozone et le moteur sont en fonctionnement. Un adaptateur venturi (25) se loge dans le collecteur d'admission du moteur (25) et le générateur d'ozone est relié à l'adaptateur par l'intermédiaire d'une conduite résistante à l'ozone (24).
