Abstract: A multi-cylinder internal combustion engine of the type having an auxiliary combustion chamber associated with each main combustion chamber, and connected thereto by a torch opening, is provided with a manifold system in which the exhaust gases are used to heat a rich air-fuel mixture supplied to the auxiliary combustion chambers and is also used to heat the lean air-fuel mixture supplied by the primary carburetor barrel to the main combustion chambers, but the lean air-fuel mixture supplied by the secondary carburetor barrel is not heated. The secondary carburetor barrel comes into action only when the engine is operating under heavy load, so that the unheated additional lean mixture improves the volumetric efficiency and thereby improves the power output of the engine. Thin wall liners and heat transfer plates having low thermal capacity are provided for the exhaust passages in the engine, the interior of the exhaust manifold, and the heat exchange surfaces for heating the rich mixture and that portion of the lean mixture provided by the primary carburetor barrel.

Abstract: An intake and exhaust system for an internal combustion engine of the type having an auxiliary combustion chamber associated with each main combustion chamber, and wherein the overall air-fuel charge to all combustion chambers is leaner than the stoichiometric ratio, so that excess air is present in the exhaust gases. The system includes integrated intake manifolds, one for connection with the main combustion chamber and the other for connection with the auxiliary combustion chamber, and an exhaust manifold for connection with the main combustion chambers. The exhaust manifold includes a stainless steel liner enveloped within and spaced from a metal casting in order to retain the heat of the exhaust gases so that the exhaust gas temperature remains at or above the temperature at which the unburned hydrocarbons in the exhaust gases will continue to burn. This temperature also promotes oxidation of carbon monoxide to carbon dioxide. The intake manifold is in thermal association with the exhaust manifold to provide a transfer of heat from the exhaust manifold to the intake manifold so that a rich mixture for the auxiliary combustion chambers and a lean mixture for the main combustion chambers are both heated in a controlled ratio. An integral heat riser member is positioned between the exhaust manifold and the intake manifold for transferring heat therebetween. The liner has a collection chamber with a baffle located therein to direct the flow of exhaust gases to insure proper heat transfer to the riser member. Another main feature of the system is to present a minimum heat capacity in association with the exhausting gases to allow the overall system to quickly achieve preferred operating conditions.

Abstract: A method of programming exhaust gas constituents is disclosed which cooperates with a unique exhaust passage liner construction resulting in an improved self-cleaning technique for internal combustion engines. The liner comprises an apparatus which preferably subdivides the outer peripheral region of the exhaust so that the Reynolds number of the outer flow is below 2300 and therefore indicative of laminar or controlled turbulent flow. The laminar transient film between the passage wall and flow is enhanced by the transient film between subdividing walls and the flow, the composite acting to reduce the heat transfer coefficient between the total flow and wall of the exhaust passage.
