    摘要： A control for the idling carbureted mixture of fuel and air of a vehicle-propelling internal combustion engine to reduce the fuel to air ratio when the vehicle is decelerating and is coupled to the engine. Engine intake manifold pressure and throttle valve setting govern the control which preferably leans the mixture sufficiently so it is not combustible in the engine.

    摘要： Methods and means are disclosed for controlling the flow of gasoline through the idle jet of the carburetor of an automotive internal combustion engine. To improve mileage, flow through the idle jet is discontinued when the vehicle is traveling above a minimum speed provided that the vacuum in the intake manifold does not fall too low. Additional fuel economy may be obtained by stopping the flow of gasoline through the idle jet at any time the throttle is advanced and fuel flows through the main jets of the carburetor.In the simplest mechanical embodiment of the invention, the flow of fuel through the idle jet feed line is controlled by an atmospheric vent provided in the idle jet feed line. When the vent is open to atmosphere, the vacuum from the intake manifold is broken and no fuel will be drawn from the carburetor float bowl by the idle jet to the engine. The atmospheric vent is conveniently controlled by the combination of an electrical solenoid that is responsive to intake manifold vacuum and a microswitch that is responsive to throttle advance.

    摘要： The carburetor air/fuel idle system mixture channel has an air port that is normally closed by a manifold vacuum sensitive valve; during either engine deceleration or shutdown operations, the air valve is opened to bleed the vacuum signal on the idle system fuel jet, to terminate idle system fuel, air flowing through the idle system air/fuel mixture channel to the engine cylinders.
