Digital Fuel-Measurement System 820767

An intelligent fuel-metering system which computes vehicle fuel economy based on measurements of fuel consumed, distance traveled and elapsed time was developed for laboratory use. It can be used with either carbureted or fuel-injected engines using gasoline, alcohol, gasohol or diesel fuel either as a stand alone or as a host computer-controlled system. The system is capable of checking itself by purging its fuel-delivering hardware and verifying the calibration of the fuel transducer. Its modes of operation, fuel flow system, microcomputer-coordinated measurements, computation, and video display of measurement results are discussed.
