Abstract
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-emulsion discharge member is situated generally in the induction passage downstream of the throttle valve, an air passage communicates between a source of air and the fuel-air-emulsion discharge member, the air passage has a flow restrictor therein which provides for sonic flow therethrough, 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-emulsion discharge member, the fuel-air-emulsion discharge member has a plurality of discharge ports spaced from each other and directed into the induction passage, a heater is provided in order to at least at times heat the fuel-air-emulsion discharge member in order to thereby heat the fuel-air-emulsion as flows through the fuel-air-emulsion discharge member.
