Abstract

A fuel distribution control for the fuel control system of an internal combustion engine having a fuel control computer generating fuel delivery signals indicative of the engines fuel requirements, means for delivering fuel to the engine in response to said fuel delivery signals and means for generating amplitude signals indicative of the magnitudes of the torque impulses generated by the individual cylinders, the fuel distribution control comprising means for correcting the amplitude signals as a function of the cylinders position along the engine's crankshaft and engine speed, means for generating an average amplitude signal for each cylinder, means for generating an individual difference signal for each cylinder indicative of the difference between the average amplitude signal for the individual cylinders and the average amplitude of all the cylinders, means for generating a fuel correction for each individual cylinder from said difference signals, and means for summing the fuel correction signal with the fuel delivery to generate a corrected fuel delivery signal operative to equalize the contribution of each cylinder to the total output torque of the engine.
