FUEL INJECTION APPARATUS AND SYSTEM Abstract of the Disclosure A fuel metering apparatus is shown as having a throttle body with an induction passage therethrough and a throttle valve for controlling flow through the induction passage, a fuel-air mixture discharge member is situated generally in the induction passage downstream of the throttle valve, an air passage communicates be- tween a source of air and the fuel-air mixture discharge member, the air passage also includes a flow restrictor therein which provides for sonic flow therethrough, and a fuel metering valving assembly is effective for meter- ing liquid fuel at a superatmospheric pressure and de- livering such metered liquid fuel into the air passage upstream of the flow restrictor thereby causing the thusly metered liquid fuel and air to pass through the sonic flow restrictor before being discharged into the induction passage by the fuel-air mixture discharge mem- ber, the fuel-air mixture discharge member has a plurality of discharge ports spaced from each other and directed generally radially inwardly of the induction passage.
