ABSTRACT:
In an electronic fuel injecting method for an internal combustion engine, wherein fuel injection timings for every groups are controlled in accordance with reference signals variable in the proximity of intake top dead center of a predetermined cylinder and the angle signals variable at every predetermined rotary angles, during a low rotational speed operation of the engine, all of the cylinders perform injections simultaneously in accordance with the angle signals according to the necessity, during a medium rotational speed operation of the engine, group injections with the cylinders being discriminated by the reference signal are performed in accordance with the reference signals and the angle signals, and, during a high rotational speed operation of the engine, group injections with the cylinders being not discriminated by the reference signal are performed in accordance with the angle signals according to the necessity.
