    Abstract: An internal-combustion spark-ignition V-8 piston engine has a main exhaust gas reaction chamber positioned between the two banks of cylinders. Each cylinder has a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle restriction. Valved intake passages supply lean mixture to the main combustion chambers and rich mixture to the auxiliary combustion chambers. A spark plug is associated with each auxiliary combustion chamber. Valved exhaust passages supply hot exhaust gases to auxiliary exhaust gas reaction chambers, each of which projects through an insulated wall of the main exhaust gas reaction chamber, and discharges into it. Each of the auxiliary reaction chambers is substantially larger in cross-section than each exhaust passage and each is substantially smaller in volume than the main reaction chamber and helps to minimize unwanted pollutants such as unburned nydrocarbons and carbon monoxide in the exhaust gases by maintaining the exhaust gases at relatively high temperature and for relatively long time periods before discharge into the atmosphere, and over a wide range of engine speeds and loads. A separate air pump is not required.

    Abstract: A three-valve stratified-charge internal combustion piston engine has an auxiliary combustion chamber connected to each main combustion chamber through a torch nozzle. A rich mixture is supplied to the auxiliary chamber and a lean mixture is supplied to the main chamber. A portion of the exhaust gases from the main chamber is recirculated through a control valve to mix with the rich mixture supplied to the auxiliary chamber. For loaded conditions of the engine, additional exhaust gases from the main chamber are recirculated through a control valve to mix with the lean mixture supplied to the main chamber. The control valves are automatically operated by means responsive to engine operating conditions.

    Abstract: An internal combustion engine employs a multiple throat carburetor which supplies a lean mixture to each main chamber and a rich combustible mixture to each auxiliary combustion chamber. Exhaust gases from each main chamber are used to heat the incoming rich mixture to a relatively high degree and to heat the incoming lean mixture to a lesser degree. The intake passage for the incoming lean mixture is placed directly above a chamber in the exhaust passage and is separated therefrom by a first shield in the form of a substantially horizontal metallic plate. A multiple throat carburetor is positioned directly above a chamber in the intake passage for the lean mixture and is separated therefrom by a second shield, substantially horizontal, comprising a metal plate with an upturned peripheral edge.

    Abstract: An internal combustion engine has a main and auxiliary combustion chamber, a main and auxiliary carburetor and a main and auxiliary intake pipe providing communication between the respective carburetors and the chambers. The chambers are connected by a torch nozzle and an exhaust pipe is positioned in communication with the main combustion chamber. The main and auxiliary intake pipes and the exhaust pipes are integrally formed and positioned on the same side of the engine. A casing disposed about the pipes aids in the heating of the air fuel mixture and provides protection to the intake and exhaust apparatus.

    Abstract: A four-cycle internal combustion engine has eight cylinders each provided with a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle. A carburetor has a venturi throat supplying rich mixture to each of the auxiliary chambers and other carburetor throats supplying a lean mixture to each of the main chambers. Although the effective cross sectional area of the venturi throat for the rich mixture need not be larger than the effective cross sectional area of a single torch nozzle when the engine has four cylinders or six cylinders, an eight cylinder engine requires that the venturi throat for the rich mixture be smaller than 1.4 times as large in effective cross sectional area as each of the torch nozzles.

    Abstract: An intake system for an engine of the type having an auxiliary combustion chamber associated with each main combustion chamber. The intake system includes a first system of passageways for distributing a lean air-fuel mixture to the main combustion chambers and a second system of passageways for distributing a rich air-fuel mixture to the auxiliary combustion chambers. The first passageway system includes a two throat carburetor arrangement, a single heating chamber and distribution passageways. The second passageway system includes a single throat carburetor extending down to a heating chamber between the two throats of the main carburetor and passageways connecting the heating chamber with the auxiliary combustion chambers. The heating chamber for each of the passageway systems are positioned on the exhaust manifold system in order that the fuel will be properly vaporized. The passageways between the second heating chamber and the auxiliary combustion chambers are placed in association with the exhaust manifold system for further heating of the rich air-fuel mixture.

    Abstract: Each cylinder of an internal combustion engine is provided with a main combustion chamber and an auxiliary combustion chamber connected by a torch nozzle. A rich mixture is heated before entering into the auxiliary chamber where it is ignited by a spark plug to project a flame through the torch nozzle to ignite a lean mixture in the main combustion chamber. The heating of the rich intake mixture may be accomplished by utilizing heat from the engine exhaust system, and a liner pipe insulated from the water cooled cylinder head carries the rich mixture to the auxiliary chamber to minimize condensation of fuel.
