Abstract
A fuel consumption rate detecting apparatus comprises a circuit for representing fuel consumption amount per unit time, a pulse generator for generating a pulse signal whose pulse width is inversely proportional to the fuel consumption and whose frequency is inversely proportional to the vehicle speed, and meter circuit for measuring the mean value of the pulse signal, which is, in turn, proportional to the fuel consumption rate.
