Abstract

In an electronically controlled fuel injection apparatus having a fuel injection pump with a fuel regulating member, computing unit for calculating target data relating to a target amount of fuel injection in response to an engine condition signal, the computing unit comprises first circuit for performing two dimensional map calculation in response to the engine condition condition signal so as to obtain plural sets of data pairs of position data of the fuel regulating member and the corresponding engine speed data, and second circuit responsive to the speed data for carrying out an interpolation calculation on the basis of the plural sets of data pairs in order to obtain data relating to the target amount of fuel injection at the engine speed at each instant. The interpolation calculation can be accomplished merely by a two dimensional interpolation calculation so that the time required for calculating the target amount of fuel injection can be remarkably reduced.
