  • Fuel injector with electronic control circuit
    Patent number: 4782809
    Abstract: A fixed volume receiving cavity (18) of a fuel injector (11) receives fuel from a fuel inlet valve means (23, 24) in accordance with the time duration(T.sub.A) of fuel metering control signal pulses (100). Injection occurrence control signal pulses ( b 101) actuate a compressed air inlet valve means (26-30) connected to the cavity to inject the contents of the cavity through an outlet valve (20) and into a combustion chamber (15) of an engine. The fuel metering pulses (100) are developed by a microprocessor (50). Circuitry (53-66; 70-79,66) separate from and external to the microprocessor receives the fuel metering control signal pulses and provides, in response thereto, the fuel injection occurrence control signal pulses. Use of a fixed volume receiving cavity in the injector, in combination with the time-controlled fuel inlet valve means, eliminates many mechanical likages required in most prior injectors.
