Engine with exhaust reactor arranged for early ignition

Claim 2

An exhaust manifold reactor in combination with an internal combustion engine having a plurality of combustion chambers and an exhaust port from each combustion chamber, said manifold reactor comprising a housing defining a main reaction chamber, first inlet passage defining means connecting said main reaction chamber directly with a plurality but not all of said engine exhaust ports, baffle means defining an ignition chamber connecting with said main chamber,said baffle means being formed from heat conducting metal and at least in part separating said ignition chamber from said main chamber so as to form a heat conducting path therebetween, second inlet passage means directly connecting said ignition chamber with one of said combustion chambers not direCtly connected with said main chamber, said second inlet passage means being spaced from the connection of said main and ignition chambers to provide for extended residence of exhaust gases from said one combustion chamber in said ignition chamber before passing into said main chamber, and exhaust passage means from said main chamber and spaced from said first inlet passage means and from the connection of said main and ignition chambers to provide for extended residence of engine exhaust gases in said main chamber before being exhausted therefrom.

Claim 3

An exhaust manifold reactor for use with an internal combustion engine having a plurality of combustion chambers and a plurality of exhaust ports from said combustion chambers, said manifold reactor comprising a housing defining a main reaction chamber, a plurality of spaced inlet ports connecting with said reaction chamber and adapted for connection with certain of said engine exhaust ports, exhaust port means spaced from said inlet ports to provide an extended flow path for the passage of exhaust gases through said main reaction chamber, a generally cylindrical baffle disposed within said main reaction chamber and defining, inwardly of saId baffle, an ignition chamber within and in heat exchange relation with said main reaction chamber, said baffle having an outlet opening communicating said main reaction chamber and said ignitiOn chamber at a point nearer said inlet ports than said exhaust port means, and a secondary inlet port connecting with said ignition chamber at a location spaced from said baffle outlet opening to provide an extended gas flow path therebetween, said secondary inlet port being spaced from said first-named inlet ports and adapted to be connected with One of said engine exhauSt ports not connected to said first-named inlet ports.

Claim 4

An exhaust manifold reactor for use with an internal combustion engine having a plurality of combustion chambers and a plurality of exhaust ports from said combustion chambers, said manifold reactor comprising a housing defining a main reaction chamber, a plurality of spaced inlet ports connecting with said reaction chamber and adapted for connection with certain of said engine exhaust ports, exhaust port means spaced from said inlet ports to provide an extended flow path for the passage of exhaust gases through said main reaction chamber, a generally cylindrical baffle disposed within said main reaction chamber and defining, inwardly of saId baffle, an ignition chamber within and in heat exchange relation with said main reaction chamber, said baffle having an outlet opening communicating said main reaction chamber and said ignitiOn chamber at a point nearer said inlet ports than said exhaust port means, and a secondary inlet port connecting with said ignition chamber at a location spaced from said baffle outlet opening to provide an extended gas flow path therebetween, said secondary inlet port being spaced from said first-named inlet ports and adapted to be connected with One of said engine exhauSt ports not connected to said first-named inlet ports.

Claim 5

An internal combustion engine comprising means defining a plurality of combustion chambers in which air-fuel mixtures are cyclically burned to develop power, means to supply air and fuel to said combustion chambers in predetermined desired ratios for combustion, said air-fuel supply means being arranged to supply, at least during engine warm-up operation, a higher proportion of fuel to air to at least one of said combustion chambers than to others, an exhaust reactor having an enlarged main reaction chamber and a smaller ignition chamber within said main chamber and in heat exchange relation therewith, said ignition chamber being connected with said main reaction chamber, separate passage means connecting said one combustion chamber with said ignition chamber and connecting each of said other combustion chambers with said main reaction chamber, and secondary air supply means connected to each Of said passage means to supply air thereto for burning in the reactor of combustibles in the exhaust gases, said secondary air supply means being arranged to supply a proportionally greater amount of air to the passage means from said one combustion chamber than to the passage means from said other combustion chamber to provide sufficient air for burning the excess fuel in the exhaust gases of said one combustion chamber.

Claim 6

An internal combustion engine comprising means defining a plurality of combustion chambers in which air-fuel mixtures are cyclically burned to develop power, means to supply air and fuel to said combustion chambers in predetermined desired ratios for combustion, said air-fuel supply means being arranged to supply, at least during engine warm-up operation, a higher proportion of fuel to air to at least one of said combustion chambers than to others, an exhaust reactor having an enlarged main reaction chamber and a smaller ignition chamber within said main chamber and in heat exchange relation therewith, said ignition chamber being connected with said main reaction chamber, separate passage means connecting said one combustion chamber with said ignition chamber and connecting each of said other combustion chambers with said main reaction chamber, and secondary air supply means connected to each Of said passage means to supply air thereto for burning in the reactor of combustibles in the exhaust gases, said secondary air supply means being arranged to supply a proportionally greater amount of air to the passage means from said one combustion chamber than to the passage means from said other combustion chamber to provide sufficient air for burning the excess fuel in the exhaust gases of said one combustion chamber.
