Abstract

A fuel consumption rate meter incorporating a fuel meter. The momentary amount of fuel consumed by a running vehicle is measured and the momentary fuel consumption rate is computed from the momentary amount of fuel consumed. The momentary amount of fuel consumed is integrated to give the total amount of the fuel consumed. The computed fuel consumption rate and the integrated fuel amount are indicated on the same panel.

Claims

1. A fuel-meter-combined fuel consumption rate meter for engine-mounting vehicles comprising:

measuring means for generating an output signal indicative of the momentary amount of fuel consumed by the running vehicle,

computing means for computing the momentary rate of fuel consumption and generating an output signal thereof from said output signal of said measuring means,

first indicating means comprising an ammeter with a needle responsive to said computing means output for indicating said momentary fuel consumption rate thereon in analog form in response to said output signal of said computing means,

integrating means connected to said measuring means for generating an output signal indicative of an accumulative amount of fuel consumed by integrating said output signal of said measuring means, and

second indicating means comprising a plurality of digital display elements for indicating in digital form said accumulative fuel amount on said ammeter of said first indicating means in response to said output signal of said integrating means.

2. A fuel-meter-combined fuel consumption rate meter for engine-mounting vehicles comprising:

p1 means for generating a first electric signal corresponding to the number of revolutions of an engine;

means for generating a second electric signal corresponding to the intake pressure of said engine;

a circuit for receiving said first and second electric signals to generate a third electric signal corresponding to the amount of fuel consumed by said engine;

means for generating a fourth electric signal corresponding to the speed of a vehicle;

a circuit for receiving said third and fourth signals to generate a fifth electric signal corresponding to the momentary rate of fuel consumption;

a circuit for receiving said third electric signal to generate a sixth electric signal corresponding to an accumulative amount of fuel consumed; and

means for receiving said fifth and sixth electric signal to indicate said momentary fuel consumption rate and said accumulative amount of fuel consumed on the same display panel.
