The system senses the amount of combustion air supplied to the engine, senses fuel flow velocity, and controls the amount of fuel supplied according to the amount of combustion air the fuel flow velocity.Field of SearchActuator circuit (e.g., engine condition responsive electronic circuit actuates injector valve)Having an up or up-down counter in circuit Subcircuit operates on a parameter sensor output before input to main fuel control (e.g., function generator) Having specific transducer Electric fuel injection pump governor Fuel viscosity sensor (e.g., temperature sensing) Fuel to crankcase | |
