ABSTRACT:
A fuel injection apparatus of the type which uses a servomechanism utilizing a fluid to control the fluid-communication ratio of a fuel measuring gate disposed in a fuel supply passage. The device is so designed that signals which detect the operating condition of the engine control the amount of fuel to correct the air-fuel ratio so as to provide an ideal air-fuel ratio and that the set value for the servomechanism is controlled so that the output time ratio of fuel lean and rich signals included in the above-mentioned signals may be maintained at a predetermined value, thereby shortening the time required for correcting the air-fuel ratio.
