Abstract

An automotive fuel injection system for detecting as quickly as possible the occurrence of acceleration without employing a throttle sensor to thereby perform an asynchronous fuel injection for the purpose of maintaining the air-to-fuel ratio of the combustible air-fuel mixture at an optimum value during the acceleration of the automotive engine. The automotive fuel injection system comprises a device for comparing the pressure inside the fuel intake system with an average value of the pressures inside the fuel intake system. When the pressure prevailing in the fuel intake system deviates by a predetermined quantity from the average pressure inside the fuel intake system, acceleration is deemed as actually occurring in the automotive engine and, hence, asynchronous fuel injection is effected substantially simultaneously with the detection of the occurrence of engine acceleration.
