ABSTRACT:
A signal proportional to a vehicle speed is applied to one input terminal of a differential amplifier, and the output of the differential amplifier is fed back to the other input terminal of the differential amplifier via a switch the on-time of which is proportional to consumed fuel. Then, the output of the differential amplifier is taken out as a fuel consumption signal for informing a vehicle driver the momentary fuel consumption of the vehicle on a voltmeter or ammeter.
