Abstract
A fuel injection apparatus of the type in which the degree of opening of a fuel measuring gate disposed in a fuel supply passage is controlled by air flow rate detecting means for detecting the rate of flow of air being sucked into an engine, and the amount of fuel is controlled by a solenoid valve adapted to be opened and closed by signals which detect the operating conditions of the engine, thereby compensating the air-fuel ratio, wherein a second solenoid valve is disposed in parallel with the first-mentioned solenoid valve and adapted to be opened and closed by the above-mentioned signals, so as to correct the basic air-fuel ratio which is set in connection with the air flow rate detecting means and the fuel measuring gate, thereby maintaining the air-fuel ratio at a desired constant value.
