Abstract

Abstract The air and fuel induction passage of a combustion engine is provided with air filtering structure for filtering the air entering the induction passage and fuel inlet structure for admitting fuel into the induction passage downstream from the air filtering structure. A foraminous panel constructed of conductive material is insulatively supported from the air filtering structure and disposed for passage of at least substantially all of the air moving through the air filtering structure through the foraminous panel. The fuel inlet structure includes at least a portion thereof constructed of conductive material and a source of high voltage, low amperage current is electrically connected, to the foraminous panel on one side and to the conductive portion of the fuel inlet structure on the other side.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 139 words
In combination with a combustion engine of the type including induction passage for air and fuel including air filtering means operatively associated with its inlet end and fuel inlet means for admitting fuel into said induction passage downstream from said air filtering means intermediate the inlet end of the induction passage and the outlet end thereof opening into said engine, foraminous panel means constructed of conductive material insulatively supported from said air filtering means and disposed for passage of at least substantially all of the air passing through said air filtering means through said foraminous panel means, said fuel inlet means including at least a fuel discharging portion thereof constructed of conductive material, and high voltage, low amperage current source means electrically connected to said foraminous panel means and grounded relative to said fuel inlet means fuel discharging portion.
Claim 2
Dependent Claim 139 words
In combination with a combustion engine of the type including induction passage for air and fuel including air filtering means operatively associated with its inlet end and fuel inlet means for admitting fuel into said induction passage downstream from said air filtering means intermediate the inlet end of the induction passage and the outlet end thereof opening into said engine, foraminous panel means constructed of conductive material insulatively supported from said air filtering means and disposed for passage of at least substantially all of the air passing through said air filtering means through said foraminous panel means, said fuel inlet means including at least a fuel discharging portion thereof constructed of conductive material, and high voltage, low amperage current source means electrically connected to said foraminous panel means and grounded relative to said fuel inlet means fuel discharging portion.
Claim 3
Dependent Claim 32 words
The combination of claim 1 wherein said current source means comprises the secondary voltage source of an induction coil having its primary side electrically connected to a suitable source of electrical potential.
Claim 4
Dependent Claim 25 words
The combination of claim 1 wherein said combustion engine includes an ignition system to which secondary spark voltage is supplied from said secondary voltage source.
Claim 5
Dependent Claim 65 words
The combination of claim 3 wherein said air filtering means includes means defining an annular air intake passage radially of which air passing through said air filtering means passes, said air filtering means includes an annular air filtering body concentrically disposed in said air intake passage, said foraminous panel means includes an axially short cylindrical panel concentrically disposed relative to said annular air filtering body.
Claim 6
Dependent Claim 17 words
The combination of claim 4 wherein said cylindrical panel is disposed outwardly of said air filtering body.
Claim 7
Dependent Claim 37 words
The combination of claim 4 wherein said foraminous panel means includes a second axially short cylindrical panel concentrically disposed relative to said annular body, said cylindrical panels being disposed outwardly and inwardly of said air filtering body.
