Abstract
A device designed to use exhaust gas discharged out of an engine combustion chamber by dissociating chemical substances contained in the exhaust gas such as CO, CO.sub.2, NOx, HC, etc., in an exhaust gas molecule dissociating tube and drawing components of the exhaust gas, oxygen in particular, again into the engine combustion chamber. The device is so constructed as to collect dust including the carbon component of the exhaust gas in a cyclone drum for removal from the exhaust gas, which allows all of the engine exhaust to be recycled without releasing it in the atmosphere. The device is utilizable with various engines, e.g., gasoline engines, diesel engines and so on, and well-suited to mass production on account of its simple, compact and lightweight construction.
Claims14
A device comprising:
- means for recycling substantially all of the oxygen in an exhaust gas from a combustion chamber to provide under predetermined conditions the only source of oxygen to the intake of said combustion chamber, said recycling means comprising an exhaust gas molecule dissociating tube joined to the discharge conduit of an exhaust manifold for dissociating said exhaust gas by corona processing into components including monomolecules of oxygen from the constituents in said exhaust gas, a cyclone drum connected to the outlet side of said exhaust gas molecule dissociating tube and fitted with an electrostatic precipitator tube for removing dust from said exhaust gas, a dissociated gas control reservoir joined to said electrostatic precipitator tube for controlling the flow rate of exhaust gas, an an intake manifold connected to the outlet side of said dissociated gas control reservoir through an induction tube for recycling said dissociated exhaust gas to said combustion chamber to provide the source of oxygen to the intake of said combustion chamber.
An apparatus comprising:
- means for recycling dissociated and purified exhaust gas to provide substantially all of the oxygen from the exhaust gas for use as the only source of oxygen to the intake of an engine without discharging said exhaust gas to the atmosphere under predetermined conditions, for combustion with fuel in an engine having an intake manifold and an exhaust manifold, said recycling means comprising:
- an electrostatic precipitator connected to the exhaust manifold of the engine;
- a dissociation chamber connected to said electrostatic precipitator and to the intake manifold of the engine and including a dissociated gas control reservoir connected to said dissociation chamber and to the engine intake manifold;
- and
- a cyclone drum connected to said electrostatic precipitator for removing particles from the exhaust gases in said electrostatic precipitator.
A method 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 said electrostatic precipitator and to the intake manifold of the engine and including a dissociated gas control reservoir connected to said dissociation chamber and to the engine intake manifold;
- and a cyclone drum connected to said electrostatic precipitator for removing particles from the exhaust gases in said electrostatic precipitator, said method comprising the steps of:
- dissociating the molecules of the exhaust gas from the engine in said dissociation chamber into monomolecules by subjecting said exhaust gas to the effects of a corona discharge in said dissociation chamber;
- removing carbon and other particulate matter from the exhaust in said 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.
An apparatus for use in connection with a combustion chamber which produces an exhaust gas, said apparatus comprising:
- means for dissociating substantially all of the gaseous components of exhaust gas into gaseous components which include molecular oxygen by subjecting said exhaust gas to the effects of a corona discharge;
- and
- means for recycling the dissociated gaseous components of said exhaust gas to said combustion chamber without discharging said exhaust gas or said dissociated components into the atmosphere under predetermined flow and pressure conditions, said recycling means providing said molecular oxygen to the intake of said combustion chamber for use as virtually the sole source of recycled oxygen at the intake of said combustion chamber.
