  • Apparatus for bench testing a governor
    Patent number: 5351529
    Abstract: An apparatus for testing components of an electronic engine governor is disclosed. The governor to be tested has a speed control unit responsive to a control signal for producing a fuel control signal and an amplifier coupled to the speed control for compensating engine load, and may have a load computer for producing a load signal indicative of engine loading. A voltage controlled oscillator (VCO) in the test apparatus is adapted to be coupled to the speed controller for simulating engine speed as a variable frequency output in response to an input voltage. A summing node is adapted to be responsive to the output of the speed control unit and the load computer for producing a summed input control signal to the VCO. Substitute voltage and current signals are provided as input to the load computer to check the load computer operation.
