Abstract
Abstract An accessory or attachment device for existing or newly manufactured internal combustion engines bleeds incompletely burned combustion products from the engine exhaust upstream from the exhaust manifold and returns or recycles the combustion products through the carburetor to the combustion chambers of the engine where complete burning of the products takes place. Carbon monoxide in the final exhaust from the engine is reduced almost to zero and substantially the full energy present in the hydrocarbon fuel is utilized, rather than being wasted into the atmosphere as occurs in conventional engines. The device subjects the recycled combustion products to violent agitation and comminution before returning them through the carburetor to the engine fuel induction system.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
208 words
A device for recycling combustion products in an internal combustion engine to remove carbon monoxide therefrom and to more completely burn the combustion products comprising a sleeve member forming a housing, conduit means coupling opposite ends of said sleeve member to an engine exhaust and engine fuel induction means, a male jet element supported centrally within said sleeve member in spaced relation thereto and being coaxial therewith and extending through a major portion of the length of the sleeve member and having a downstream end terminating within the sleeve member, said male jet element having a central axial bore formed therethrough from end-to-end and having plural circumferentially spaced longitudinal rows of radial ports leading from the central axial bore and opening through the peripheral surface of the male jet element approximately at the longitudinal center zone of the sleeve member, and a coacting female sleeve element inside of said sleeve member and being supported thereby in coaxial surrounding relationship to the male jet element, said female sleeve element having a plurality of elongated circumferentially spaced fingers of channel form extending for the major portion of its length and said fingers having free separated ends at the downstream end of the device, and said fingers having toothed longitudinal edges.
Claim 2
Independent Claim
208 words
A device for recycling combustion products in an internal combustion engine to remove carbon monoxide therefrom and to more completely burn the combustion products comprising a sleeve member forming a housing, conduit means coupling opposite ends of said sleeve member to an engine exhaust and engine fuel induction means, a male jet element supported centrally within said sleeve member in spaced relation thereto and being coaxial therewith and extending through a major portion of the length of the sleeve member and having a downstream end terminating within the sleeve member, said male jet element having a central axial bore formed therethrough from end-to-end and having plural circumferentially spaced longitudinal rows of radial ports leading from the central axial bore and opening through the peripheral surface of the male jet element approximately at the longitudinal center zone of the sleeve member, and a coacting female sleeve element inside of said sleeve member and being supported thereby in coaxial surrounding relationship to the male jet element, said female sleeve element having a plurality of elongated circumferentially spaced fingers of channel form extending for the major portion of its length and said fingers having free separated ends at the downstream end of the device, and said fingers having toothed longitudinal edges.
Claim 3
Dependent Claim
40 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, and said conduit means including a T-coupling and pipes connected with inlets of the T-coupling and leading from exhaust manifold sections of an engine.
Claim 4
Dependent Claim
44 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, and said spaced fingers of the female sleeve element engaging the downstream end portion of said male jet to support and center it relative to said sleeve member.
Claim 5
Dependent Claim
59 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, and said fingers of channel form being approximately V-shaped in cross section and the channels formed by the side walls of the fingers increasing in depth gradually toward the downstream tips of the fingers, the longitudinal edges of said side walls being toothed.
Claim 6
Dependent Claim
33 words
A device for recycling combustion products in an internal combustion engine as defined in claim 4, and the teeth on said fingers increasing in size gradually toward the downstream tips of the fingers.
Claim 7
Dependent Claim
44 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, and said sleeve member having a reduced diameter collar on the downstream end thereof, and downstream end portions of said fingers resting on and centered by said collar.
Claim 8
Dependent Claim
56 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, wherein said sleeve member is an externally threaded sleeve, and a pair of coupling nuts on opposite ends of the threaded sleeve and engaged with said conduit means and forming end closures for the housing formed by the sleeve member.
Claim 9
Dependent Claim
45 words
A device for recycling combustion products in an internal combustion engine as defined in claim 1, and said male jet element comprising an elongated cylindrical body portion having an upstream reduced diameter end, said end seated and supported within a bore of said conduit means.
Claim 10
Independent Claim
170 words
A device for recycling combustion products in an internal combustion engine to remove carbon monoxide from the final exhaust and to more completely burn the combustion products, said device comprising a sleeve member forming a housing and adapted for coupling between an engine exhaust system an engine fuel induction means, a male jet element disposed centrally within the sleeve member in spaced relation thereto and having a central longitudinal bore and plural radiating ports leading from said bore substantially centrally of the sleeve member, and a coacting female sleeve element within said sleeve member and supported thereby in surrounding relationship to said male jet element and being slotted to define plural spaced longitudinal fingers on said female sleeve element and passages between said fingers, whereby gaseous products passing through the bore and radiating ports of the male jet element enter the interior of the female sleeve element and the passages between said fingers prior to being released from said sleeve member for return to an engine through the carburetor thereof.
Claim 11
