Abstract
A system for reducing pollutants in internal combustion engine emissions, particularly marine electric generator engines, includes a treatment chamber having an intake opening for receiving gaseous emissions from the engine, and an exhaust opening for exiting emissions. A perforated metal tube is disposed within the treatment chamber, and an electrode is disposed within the metal tube in spaced apart relation to the metal tube. The electrode is encircled by the metal tube so that, upon applying a voltage at a predetermined frequency to the electrode, an arc is generated across the space between the electrode and the metal tube to promote a chemical reaction reducing the concentration of pollutants. The treatment chamber is contained within a manifold, and cooled by a flow of water. A supplemental air source is connected to the treatment chamber, and a chemical substrate is disposed within the treatment chamber for promoting the chemical reaction.
