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 mixture 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 mixture discharge member, the air passage also includes a flow restrictor therein which provides for sonic flow therethrough, and a solenoid type fuel metering valving assembly, having an adjustable movable electrical coil 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, 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.
