Abstract
An electronic fuel injecting method and device for an internal combustion engine, wherein a correction in accordance with the operating conditions or the like of the engine is effected on a basic injection time obtained in accordance with an intake pressure or an intake air flowrate, and a rotational speed of the engine, to thereby provide fuel in synchronism with the rotation of the engine. When the operating conditions of the engine reach a predetermined condition, fuel is provided at a predetermined injection time not in synchronism with the rotation of the engine. When requirements for non-synchronous injection take place during synchronous injection, the time period for the synchronous injection is prolonged by the appropriate non-synchronous injection time. When more than one non-synchronous injection requirement occurs during a single synchronous injection, the synchronous injection time is lengthened by a time corresponding to only one of the non-synchronous injection requirements.
