Abstract: An exhaust gas recirculation valve assembly for controlling the recirculation of exhaust gases in an internal combustion engine having a base with an exhaust gas chamber formed therein, a cover closing the chamber, a valve member mounted within the exhaust gas chamber for metering exhaust gas passage through the chamber, an actuator energizable to operate the valve within the exhaust gas chamber and a heat deflector assembly placed between the cover and the base to reduce heat transfer from the exhaust gas chamber to the actuator. The heat deflector assembly is constructed of a first gasket member which is configured to form a seal between the cover and the base and the second heat deflector member mounted to the lower surface of the gasket member, facing the exhaust gas chamber and separating the gasket member from direct impingement of exhaust gases thereon. As a result, durability of the insulative gasket member is ensured.

Abstract: An insulator supports a plurality of charge formers on the end of an intake manifold. The insulator, made in part of elastic material, thermally decouples the charge formers from the engine to reduce conduction of engine heat to the charge formers. Expansion of the intake manifold due to heat deforms the insulator, without substantially moving the charge formers so as not to deform a linkage which interconnects the charge formers.

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: The present invention provides a diaphragm carburetor wherein heat transferred from the engine to the carburetor through the insulator is reduced to lower the temperature of the carburetor unit and reduce the occurrence of bubbles in the fuel. The carburetor of the present invention is a diaphragm carburetor in which a fuel channel that extends from a pump chamber of the carburetor to a constant-pressure fuel chamber is divided into two branches to form one branch as a main fuel channel connected to the constant-pressure fuel chamber, and the other branch as a fuel circulation channel for passing the fuel through the body side surface of the carburetor on the insulator side, or the body side surface of the insulator on the carburetor side, causing the fuel to make a circuit around the carburetor, and returning the fuel to the fuel tank.
