Abstract
PURPOSE: To perform running operation of an engine within a range of its economic fuel consumption, by adequately indicating combination of the depressing amount of an accelerator pedal and the gear ratio of a geared speed changer.
CONSTITUTION: If voltage V1 in proportion to the depressing amount of an accelerator pedal is guided to a wiring 2a from a terminal 1, a characteristic converter 2 outputs reference voltage V2 to a wiring 2b in accordance with a value of voltage, and a comparator 4 comparts said reference voltage V2 with voltage in proportion to rotary speed input from a terminal 3, and if the reference voltage V2 in the wiring 2b is higher than voltage in a wiring 3a, outputs voltage to a wiring 4a then turns on a lamp 5 of green color through an amplifier 5a. While for the operating condition of an engine not within a range of economic fuel consumption, voltage is not output to the output wiring 4a not to turn on the green lamp, then voltage is output from an inverter 6a to turn on a red colored lamp 6 through an amplifier 6b.
