Abstract
Abstract This invention relates to a pre-ignition, combustion system of the type used in combination with an internal combustion engine whereby a vaporized fuel charge is created due to the exposure of heat to saturated fuel vapor. The fuel vapor is further heated to a point of near combustion immediately prior to introduction into the intake manifold of an I. C. engine. A thermerator element is provided which defines a heating chamber in which fuel is vaporized due to direct exposure with the exhaust gases of the internal combustion engine through appropriate directing of the introduced fuel or fuel vapor in direct heat transfer relation to the exhaust gases passing through at least a portion of the heating chamber defined in the thermerator. The fuel source including a substantially conventional fuel tank has air supply means leading thereto so as to supply positive air pressure serving to aid fuel passing from the fuel tank into the thermerator through a first fuel supply conduit. At least one additional auxiliary fuel supply line with fuel pump attached thereto is provided for directing fuel into the thermerator on an auxiliary or independent basis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
328 words
A precarburetor ignition system for use in combination with an internal combustion engine said system comprising: thermerator means interconnected to the intake manifold of the internal combustion engine, fuel source means, fuel supply means interconnected in fluid communication between said thermerator means and said fuel source means; said fuel supply means comprising, at least in part, supply conduit means; said thermerator means comprising heat source means disposed in direct engagement with exhaust gases from the internal combustion engine; fuel vapor separator means disposed in fluid communication between said fuel supply means and said thermerator means, spray orifice means having a predetermined configuration and connected in fluid delivery position to the interior of said fluid vapor separator means, said spray orifice means dimensioned to deliver fuel from said supply means to the interior of said fuel vapor separator means in at least a partial vapor state, said fuel vapor separator means further comprising reservoir means disposed in spaced relation to the point of connection of said spray orifice means, return conduit means interconnected between said reservoir means and said fuel supply means, said fuel vapor separator means comprising, at least in part, a substantially curvilinear longitudinal configuration, said spray orifice means connected in interconnecting relation to the interior of said fuel vapor separator means and disposed in direct fuel delivery relation to an interior curved surface of said fuel vapor separator means, whereby fluid is directed into the interior of said fuel vapor separator means toward the interior curved surface, said reservoir means disposed below the interior curved surface in fluid communication with the fuel supply, whereby excess fuel collected in said reservoir is returned to said fuel supply means; said fuel vapor separator means further comprising an air intake means disposed in fluid communication with the interior of said fuel vapor separator means, whereby air is mixed with partially vaporized fuel from said spray orifice means and delivered to said thermerator for complete vaporization upon receiving heat therefrom.
Claim 2
Dependent Claim
