ABSTRACT:
The disclosure illustrates a fuel mileage indicator which gives a dynamic reading of the fuel mileage for a vehicle powered by an internal combustion engine. As a result it indicates to the driver whether he is driving efficiently and is conserving fuel. The device consists of a variable resistance device responsive to a fuel system parameter or other engine parameter which is proportional to engine fuel flow. This variable resistance device is connected in series with a generator having a D.C. voltage output directly proportional to vehicle speed. An ammeter indicates current through the circuit and is calibrated to give an output of miles per gallon.
