A fuel consumption display device for a vehicle configured to convert and display a required fuel consumption amount based on an integrated value of the fuel consumption, the device comprising: an electronic fuel injection device that generates the fuel injection pulse signal; Based on the reference clock generator that generates a reference clock pulse for measuring the time corresponding to the pulse width of the fuel injection pulse signal and the count value of the reference clock pulse generated at the time corresponding to the pulse width of the fuel injection pulse signal, the fuel A fuel injection time measuring means for measuring the fuel injection time based on an injection pulse signal, a fuel injection amount conversion means for converting the fuel injection time measured by the fuel injection time measuring means into a fuel injection amount, and calculating a monthly fuel consumption amount. For this purpose, a calendar clock that measures the month, date, and time, and a fuel injection amount calculated by a fuel injection amount conversion means are continuously calculated for a period set by the calendar clock,
A fuel consumption display device for a vehicle, comprising: a fuel consumption accumulating means for calculating the monthly fuel consumption as a counted value; and a display means for displaying the monthly fuel consumption calculated by the fuel consumption accumulating means. .
