PURPOSE:To perform simplification and cost down, in an electronic fuel controller of a vehicle internal combustion engine, by dividing a running condition of a vehicle into plural ranges in accordance with air-fuel ratio and equipping a display unit which displays a running range in accordance with said plural ranges. CONSTITUTION:A device is constituted such that a running condition of a vehicle is detected by an engine speed from an ignition coil 22 and a load signal from an intake pipe negative pressure sensor 23, and an injected quantity from an injection pump 25 is determined by a computer unit 24 in an electronic fuel controller. Then a display lamp 26, showing a running condition, is turned on by a command of the computer unit 24. Here the display lamp 26 is turned on to respectively display a full open time characteristic 11 of a throttle valve, enrich range 12 required with rich fuel, output range 13 with maximum combustion efficiency, feedback range 14, economical running range 15 and fuel cut range 16 at deceleration. |
