Method and apparatus for reducing emission of pollutants in exhaust gas from internal combustion engine

Claim 2

Apparatus for combusting the combustible contaminants contained in the exhaust gas of an internal combustion engine and including a conventional exhaust manifold, exhaust pipe and muffler comprising: a. an engine driven air pump for delivering air to the exhaust manifold; b. an afterburner disposed downstream from the muffler and having apertured end walls, said afterburner having a transverse baffle between its end walls with spaced apertures in said baffle adjacent its periphery whereby gas passing through said afterburner passes through said apertures in said baffle; c. a first plurality of spark plugs, each disposed adjacent a corresponding one of said apertures in said baffle; d. a second plurality of spark plugs positioned adjacent to and outside said apertured end walls of said afterburner; and e. a vibrating type coil for providing continuous sparking across the gaps of said plugs for effecting ignition of the combustibles and the air admixed with same for substantially complete combustion of same.

Claim 3

Apparatus in accordance with claim 1 including a third plurality of spark plugs positioned adjacent to and outside said apertured end wall of said afterburner opposite that of said apertured end wall adjacent to said second plurality of spark plugs.

Claim 4

Apparatus for reducing the emission of polluTants contained in the exhaust gas from an internal combustion engine having a conventional exhaust manifold and exhaust pipe, comprising: a. an engine driven air pump for delivering air to the exhaust manifold; b. an afterburner connected to said exhaust pipe and having apertured end walls, said afterburner having a transverse baffle between its end walls with spaced apertures in said baffle adjacent its periphery whereby gas passing through said afterburner passes through said apertures in said baffle; c. a first plurality of spark plugs, each disposed adjacent a corresponding one of said apertures in said baffle; d. a second and third plurality of spark plugs positioned adjacent to and outside said apertured endwalls of said afterburner, said second plurality of spark plugs being adjacent one end wall of said afterburner and said third plurality of spark plugs being adjacent the other end wall of said afterburner; and e. a vibrating type coil for providing continuous sparking across the gaps of said first, second and third plurality of plugs for effecting ignition of the combustibles and the air admixed with same.

Claim 5

Apparatus for reducing the emission of polluTants contained in the exhaust gas from an internal combustion engine having a conventional exhaust manifold and exhaust pipe, comprising: a. an engine driven air pump for delivering air to the exhaust manifold; b. an afterburner connected to said exhaust pipe and having apertured end walls, said afterburner having a transverse baffle between its end walls with spaced apertures in said baffle adjacent its periphery whereby gas passing through said afterburner passes through said apertures in said baffle; c. a first plurality of spark plugs, each disposed adjacent a corresponding one of said apertures in said baffle; d. a second and third plurality of spark plugs positioned adjacent to and outside said apertured endwalls of said afterburner, said second plurality of spark plugs being adjacent one end wall of said afterburner and said third plurality of spark plugs being adjacent the other end wall of said afterburner; and e. a vibrating type coil for providing continuous sparking across the gaps of said first, second and third plurality of plugs for effecting ignition of the combustibles and the air admixed with same.
