Asmus, T W

A fuel metering apparatus is described for supplying the air and metered rates of fuel flow to an internal combustion engine comprising: a throttle body means having a main fluid induction passage means for supplying the engine with fuel and air; throttle valve means including a pivotal throttle blade movable between a substantially closed position for idle and a wide open position for high speed engine operation for controlling the flow rate of air and fuel into the engine; the throttle body means forms an interior cavity near the fluid induction passage means; a fuel injection device has an outlet end to the cavity of the throttle body for introducing fuel spray; a first passage means connecting the cavity and the main fluid induction passage means of the housing at a location downstream of the throttle valve means; second passage means connecting the cavity and the main fluid induction passage means of the housing at a location upstream of the throttle valve; means at the upstream location for producing a lower fluid pressure upstream of throttle valve when moved from its closed position. Fuel from the cavity is drawn through the second passage means and into the main fluid induction passage means when the throttle valve is moved from a closed operative position.
