Abstract
A fuel distribution control for an internal combustion engine having a fuel control computer and fuel delivery means for delivering fuel to the engine in response to electrical signals. A signal generator generating first signals indicative of the incremental rotational velocity of the engine's output member resulting from the torque impulses imparted to the output member by the individual cylinders, averaging means for generating from said first signal an average rotational velocity signal, a circuit for generating a difference signal indicative of the difference between said first signals and said average rotational velocity signal, integrator means for individually accumulating said difference signals to generate a correction signal for each cylinder, means for averaging said correction signal to generate an average correction signal, means for summing said correction signal with the base fuel quantity signals generated by the fuel control computer to generate intermediate fuel quantity signals, and means for summing the correction signals to said intermediate fuel quantity signal to generate a corrected fuel quantity signal activating the fuel delivery means to deliver a quanti…
