ABSTRACT:
A continuous fuel injection system for metering out fuel to the induction tube of an internal combustion engine. An air flow metering assembly in the induction tube includes a baffle plate which is set with its plane perpendicular to the air flow vector and is mounted on a shaft which slides axially in bearings. As a result of the air flow, the baffle plate is displaced axially to varying extent and this displacement is opposed by a restoring force provided by pressurized fuel and subject to adjustment on the basis of engine variables. A vaned impeller wheel, mounted on the baffle shaft, causes rotation of the shaft in the bearings, thereby eliminating static friction and preventing hysteresis effects. The centrifugal forces generated by the rotation aid in distributing the fuel and in admixing it with the incoming air.
