Fuel efficient, low pollution carburetor and methods

A carburetor system for an internal combustion engine comprising:

• source means for delivery of liquid hydrocarbon fuel;
• fuel atomizing, vaporizing and air mixing means comprising a plurality of spaced turbulent vortical flow sites disposed seriatim along the flow path thereof and means for introducing a quantity of air into the flow path at each turbulent vortical flow site for atomizing and vaporizing the fuel and homogenizing the fuel/air mixture without the specific application of heat to the mixture;
• separating means comprising a chamber wherein the fuel/air mixture is vortically circulated causing condensation and accumulation of unvaporized fuel on the interior walls thereof and further comprising gravity flow means by which the separated liquid fuel is returned to the fuel atomizing, vaporizing and air mixing means;
• and
• exit means for delivery of a homogenous mixture of vaporized fuel and air to the engine without the specific application of heat to the mixture.

A carburetor system for an internal combustion engine comprising:

• means by which liquid fuel in unaltered form is continuously delivered directly from a source to the input of a carburetor system;
• means by which said unaltered fuel is initially continuously atomized and the fuel/air mixture derived therefrom is successively further continuously atomized and vaporized using a plurality of streams of secondary air respectively introduced at a plurality of sites one successively downstream of the previous one along the fuel/air flow path within the carburetor system upstream of a site where primary carburetor air is continuously introduced;
• means at said primary carburetor air site by which primary carburetor air is mixed with repeatedly atomized and vaporized fuel/air mixture;
• means downstream of the primary carburetor air means but upstream of an intake manifold receiving the resultant discharge comprising the primary air and the atomized, vaporized fuel/air mixture, said downstream means comprising means continuously horizontally vortically separating excess fuel from said discharge and means directly and continuously returning the separated excess fuel to the fuel atomizing and vaporizing means for recycling and means delivering the remaining atomized fuel/primary air mixture to the intake manifold of the engine.

A carburetor system for an internal combustion engine comprising:

• source means for delivery of hydrocarbon fuel;
• fuel atomizing, vaporizing and air mixing means having a flow path selectively receiving fuel from the source means;
• primary air means through which primary air is caused to pass and into which the air and fuel from the fuel atomizing, vaporizing and air mixing means are discharged;
• means by which fuel/air effluent from the primary air means is caused to be fed into the intake manifold;
• the fuel atomizing, vaporizing and air mixing means comprising a plurality of spaced turbulent vortical flow sites disposed seriatim along the flow path thereof and means for introducing a quantity of air into the flow path at each turbulent vortical flow site;
• fume recycling means communicating with at least one of said turbulent vortical flow sites and communicating a relatively small quantity of fumes to at least one of said air introducing means whereby fumes and air are caused to be introduced into the flow path at said site.
