Abstract

PURPOSE:To display the accurate injection amount, by detecting fuel temperature, and compensating the display value of the injection amount at a reference temperature based on said detected temperature. CONSTITUTION:When the fuel temperature is increased during the measurement, the injection amount is decreased. A signal VP is reduced accordingly. Meanwhile, a compensating circuit 14 is constituted so that the increase in fuel temperature is detected and an amplification factor is increased with the increase in the fuel temperatur. Therefore the value corresponding to the increase in the temperature, i.e. the decrease in the signal VP is increased. Thus the signal VP is compensated by the compensating circuit 14, and the display value of the injection amount becomes the value equivalent to the display value at the reference temperature. In this constitution, the display value of the injection amount is compensated with the increase in the fuel temperature, and the accurate injection amount can be displayed.
