Martin, B J

A method is described of measuring the distance per amount of fuel that is being consumed by an engine of a vehicle at any one instant. The method consists of measuring the fuel flow rate to the engine of the vehicle, measuring the vehicle speed, and dividing the vehicle speed by the vehicle fuel flow rate. The fuel for the engine is injected through a fuel injection nozzle which is opened for fuel injection by providing the injection nozzle with electrical pulses during periods in which the fuel is to be fed to the engine, and the fuel flow rate is measured by measuring and multiplying together the time that the injection nozzle is open for fuel injection and the repetition time of the pulses.
