Powered vehicle fuel consumption measurement - for computation and display of average consumption and remaining range

摘要

The system is for measurement and display of fuel used, with or without display of the remaining fuel quantity, as well as for determination and display of average consumption and distance achievable with remaining fuel. Fuel flow is measured and displayed on one or more additive or subtractive counters with calibrated or null position indicating displays. Digital indication may be used. Average fuel consumption relative to a nominal or desired value may be electronically or mechanically computed from measured fuel consumption and distance travelled, and displayed periodically or continually.
