Apparatus for indicating the distance over which a vehicle can travel with the residual fuel

An apparatus for indicating the distance over which a vehicle can travel with the residual fuel remaining in the fuel tank of said vehicle, comprsising:

• (a) first means for producing a first signal indicative of the distance travelled by said vehicle and the amount of fuel consumed by the engine of said vehicle, said first means including means for producing a second signal indicative of the distance travelled by said vehicle per a predetermined period of time, means for producing a third signal indicative of the amount of fuel supplied to said engine per said predetermined period of time, and means for dividing said distance indicated by said second signal by said amount of fuel indicated by said third signal, said means for producing said third signal including a wobble plate flow-rate sensor disposed in the fuel passage of the carburetor of said engine, said wobble plate flow-rate sensor producing a signal the frequency of which is proportional to the fuel flow rate, and a counter for producing said third signal by counting the number of pulses produced in response to the flow-rate sensor output signal for said predetermined period of time,
• (b) second means for producing a fourth signal indicative of the amount of fuel contained in the fuel tank of said vehicle;
• (c) third means for producing a fifth signal indicative of the distance over which said vehicle can travel with the amount of fuel remaining in said fuel tank by multiplying said first signal by said fourth signal;
• and
• (d) fourth means for displaying said distance indicated by said fifth signal.

An apparatus for indicating the distance over which a vehicle can travel with the residual fuel remaining in the fuel tank of said vehicle, comprising:

• (a) first means for producing a first signal indicative of the distance travelled by said vehicle with a unit amount of fuel in view of the distance travelled by said vehicle and the amount of fuel consumed by the engine of said vehicle, said first means including means for producing a second signal when the distance travelled by said vehicle equals a predetermined distance, means responsive to said second signal for producing a third signal indicative of the amount of fuel supplied to said engine during a travel of said predetermined distance, and means for dividing said predetermined distance by said amount of fuel indicated by said third signal, said means for producing said third signal including a clock pulse generator, a flip-flop responsive to the operation of said fuel injectors, gate means responsive to the flip-flop output signal for transmitting the clock pulses for a period of time for which fuel injectors are energized, and a counter for producing said third signal by counting the number of pulses transmitted via said gate means during said travel of said predetermined distance;
• (b) second means for producing a fourth signal indicative of the amount of fuel contained in the fuel tank of said vehicle;
• (c) third means for producing a fifth signal indicative of the distance over which said vehicle can travel with the amount of fuel remaining in said fuel tank by multiplying said first signal by said fourth signal;
• and
• (d) fourth means for displaying said distance indicated by said fifth signal.
