Abstract
A fuel supply control control method for an internal combustion engine, which is adapted to determine a quantity of fuel for supply to the engine by multiplying a basic value of the quantity of fuel determined as a function of at least one operating parameter of the engine, by correction coefficients dependent upon operating conditions of the engine, and adding to the basic value correction variables dependent upon operating conditions of the engine, and to supply the determined quantity of fuel to the engine. Values of predetermined one of the above correction coefficients and predetermined one of the above correction variables are determined, which correspond to a set desired value of output voltage of a single voltage creating means. The basic value of the quantity of fuel is corrected by the determined values of the predetermined one correction coefficient and the predetermined one correction variable through multiplication and addition, respectively, to determine the quantity of fuel. Preferably, a plurality of pairs of a value of the predetermined one correction coefficient and a value of the predetermined one correction variable are stored beforehand, and one pair is selecte…
