ABSTRACT:
A fuel injection system for a multi-cylinder internal combustion engine wherein fuel injectors are provided for each of the cylinders. The injectors are divided into two groups, the cylinders in each of the groups having operational phases which are spaced from each other by a crank angle of 360 degrees. Injection systems are provided for each group for attaining independent injections between the groups. In each of the groups, a basic amount of fuel for one engine cycle, and then a final injection amount, is calculated, as a difference of the basic amount with respect to the actual amount of fuel injected during a preceding injection of the corresponding group. An injection of a precise amount of fuel is attained irrespective of any change in the engine condition.
