A tubular body projects through the normal inlet opening in the inlet manifold of a conventional internal combustion engine. The quantity of fuel mixture flowing through the bore in the body is controlled by a throttle valve which is reciprocally movable relative the discharge end of the body which resides within the manifold. Biasing means normally retracts the valve to an engine idle position. The valve is extended in response to engine demand. Droplets of liquid within the fuel mixture are atomized in response to an annular deflector which directs the mixture from the sidewall of the bore to be impinged upon the planar surface of the valve. A stationary screen encompassing the valve further atomizes the mixture. Baffels are provided to direct the fuel charge toward the combustion chambers.

Atomizing valve apparatus for internal combustion engine

A drive unit including an engine and steerable wheels, is pivotally connected to the forward end of a chassis, including a body and ground support wheels. A pair of struts movably mounted to the chassis, equilaterally outboard and above the pivotal connection, extend downwardly inward to the drive unit and are movably affixed. In response to the natural tilt of the chassis while transversing a corner, weight is transferred through the struts to equalize traction upon the steerable wheels.

Motor vehicle

A combustible air-liquid fuel mixture having a substantially constant air-to-fuel ratio is produced for delivery to the intake manifold of an engine. Air is passed through a fluid flow device having a variable area throat zone to increase the velocity of the air to sonic, and the area of the throat zone is varied in correlation with operating demands imposed upon the engine for which the mixture is produced. Liquid fuel is metered from a supply into the air stream at or before the throat zone in direct proportion to the cross-sectional area of the throat zone. The pressure of the high velocity air stream is sensed at a point where it bears a predictable relationship to atmospheric pressure, and the rate of fuel delivered into the air stream is adjusted in response to changes in the air pressure sensed so that the air-to-fuel ratio of the mixture is maintained substantially constant. Due to the particular design of the fluid flow device, air at sonic velocity passes through the throat zone over substantially the entire operating range of the engine down to low manifold vacuum levels. During the relatively brief subsonic mode of operation when the manifold vacuum levels are quite low, the fluid flow device functions as a metering venturi to introduce the liquid fuel into the varying velocity air stream.
