Smog control system employing an emulsion of water in gasoline

Abstract

Abstract A FUEL SYSTEM FOR REDUCING NITROGEN OXIDES AND CARBON MONOXIDE IN THE EXHAUST GAS EMISSIONS OF AN INTERNAL COMBUSTION ENGINE INCLUDES A STORAGE TANK FOR GASOLINE AND A DISSOLVED EMULSIFYING AGENT, A STORAGE TANK FOR DEIONIZED WATER, AND MEANS FOR PUMPING CONTROLLED VOLUMES OF THE GASOLINE AND EMULSIFYING AGENT AND THE WATER TO AN EMULSIFYING CHAMBER AND THENCE TO THE ENGINE. IN ONE FORM OF THE INVENTION, ROTARY STIRRING MEANS WITHIN THE EMULSIFYING CHAMBER EMULSIFY THE WATER IN GASOLINE, AND THE EMULSION IS THEN INTRODUCED INTO THE ENGINE CARBURETOR. MEANS PROVIDES FOR CONTINUOUS, UNINTERRUPTED RECIRCULATION OF A PORTION OF THE EMULSION ACCUMULATED IN THE CARBURETOR FUEL CHAMBER TO THE EMULSIFYING CHAMBER. IN ANOTHER FORM OF THE INVENTION, A CENTRIFUGAL PUMP EMULSIFIES THE WATER IN THE GASOLINE. THE EMULSION IS THEN PUMPED INTO THE ENGINE CYLINDERS BY DIRECT FUEL INJECTION. THE EMULSION SUBSTANTIALLY REDUCES THE REACTION TEMPERATURE OF GASOLINE AND AIR IN THE ENGINE CYLINDERS, AND THEREBY REDUCES THE FORMATION OF NITROGEN OXIDES WHICH ARE A MAJOR CAUSE OF AIR POLLUTION.
