ABSTRACT:
A device for indicating the fuel consumption rate of an internal combustion engine. The device includes a potentiometer having a sliding contact engaging either a substantially linear resistor portion when the engine is operating under partial to full load, or a separate portion when the engine is operated in the idling mode or the deceleration mode. The sliding contact is connected with the engine throttle for adjusting the position of the sliding contact in accordance with the amount of fuel supplied to the engine. A voltage source is connected to the linear portion of the potentiometer, and to the separate portion, with a switching means interposed in the latter case for selectively supplying different voltages to the separate portion depending upon whether the engine is in the idling mode or deceleration mode, for indicating a higher or lower fuel consumption rate, respectively, on a fuel consumption rate indicator electrically connected to the sliding contact.
