A fuel consumption indicating apparatus of an engine is provided to prevent an engine from being damaged, and reduce the risk caused by the power short by being plugged into a cigar jack instead using an injector signal wire. A fuel consumption indicating apparatus of an engine comprises a direct current power stabilization device(110) whose one side is connected to the direct current power generated at an engine and applied through a cigar jack; an amplifier(101) to which an alternating current signal component is applied through a connection condenser C1; a filter(102) to which the output of the amplifier is applied; a level exchanger(103) to which the output of the filter is applied ; a port capable of reading out a trigger signal(105) among plural input ports of a microprocessor(106), to which the output of the level exchanger is applied; an input port(104) of an analog/digital exchanger of the microprocessor to which the output of the filter is applied; an indicator(LCD or LED, 108) connected to an input port at one side of the microprocessor; a switch(109) for inputting or manipulating data connected to one side of the microprocessor; and a GPS(Global Positioning System) connected to a communication port of the microprocessor.
