ABSTRACT:
An electronically controlled fuel injection method for controlling a fuel injection valve of an intake system by electric signals characterized in that: from an input level X.sub.n-1 to be fed into a computation section from sensors at a previous fuel injection rate computation time T.sub.n-1, an input level X.sub.n to be fed into the sensors at a present fuel injection rate computation time T.sub.n, a delay time until a physical amount to be detected reaches an input point in the computation section by way of the sensors, and a time A.sub.n at which a cylinder to which a fuel is supplied by an amount based on the present fuel injection rate computation reaches a bottom dead center on a subsequent intake stroke, the following equation is computed; ##EQU1## and, C.sub.n is used as data on the physical amount for executing a present fuel injection rate computation.
