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 induc- tion passage downstream of the throttle valve, an air passage communicates between a source of air and the fuel-air mixture discharge member, the air passage also includes a flow restric- tor therein which provides for sonic flow therethrough, and a fuel metering valving assembly is effective for metering liquid fuel at a superatmospheric pressure and delivering 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 member.
