ABSTRACT:
A fuel control apparatus comprises a fuel supplying means for supplying fuel to an internal combustion engine depending on the operation of a fuel control valve, a hot-wire type intake air quantity sensor disposed in an air-intake passage for the internal combustion engine to detect the quantity of air passing therethrough, a memory means which is adapted to accumulate an output from the intake air quantity sensor, the number of revolution of sand internal combustion engine, or the length of time in operation of the internal combustion engine, and holds the value obtained by the accumulation after the engine is stopped, and a control means for heating a hot wire at a temperature higher than a temperature in the normal operation so as to burn off a deposit on the hot wire after the accumulated value in the memory means reached a predetermined value and the engines is stopped.
