ABSTRACT:
A fuel distribution control system for equalizing the amplitude of the torque impulses imparted to the crankshaft of an internal combustion engine having a fuel control computer generating fuel quantity signals indicative of the engines fuel requirements, fuel delivery means delivering fuel to the engine in response to the fuel quantity signals and means responsive to the instantaneous rotational velocity of the engine's crankshaft for generating signals indicative of the amplitude and phase angle of the torque impulses imparted to the engine's crankshaft by the individual cylinder. The distribution control including means for correcting the amplitude signal for errors in the phase angle of the torque impulses, means for generating an amplitude error signal indicative of the difference between the corrected amplitude signal and a desired amplitude, means for storing the amplitude error signal generated with respect to each cylinder to generate fuel correction signals and means for summing the fuel correction signals to the fuel quantity signals.
