Suzuki, N

A method is described of burning fuel in the combustion chamber of an engine using an apparatus of the type which comprises an electrostatic precipitator connected to the exhaust manifold of the engine; a dissociation chamber connected to the electrostatic precipitator and to the intake manifold of the engine and including a dissociated gas control reservoir connected to the dissociation chamber and to the engine intake manifold; and a cyclone drum connected to the electrostatic precipitator for removing particles from the exhaust gases in the electrostatic precipitator. The method consists of: dissociating the molecules of the exhaust gas from the engine in the dissociation chamber into monomolecules by subjecting the exhaust gas to the effects of a corona discharge in the dissociation chamber; removing carbon and other particulate matter from the exhaust in the electrostatic precipitator and cyclone drum to dedust the exhaust gas; and igniting a mixture of fuel and the dedusted exhaust gas in the combustion chamber of the engine, whereby fuel is initially oxidized solely by an oxygen component of the dissociated exhaust gas.
