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.

A fuel distribution control for an internal combustion engine comprising: means for computing the phase angle and amplitude signals indicative of the torque impulses applied to a rotary member of the engine by the combustion process in each engine cylinder; first difference means for comparing said computed phase angle signal with a reference phase angle to generate a phase angle correction signal; first sum means for summing said computed amplitude signal with said phase angle correction signal to generate a corrected amplitude signal; second difference means for comparing said corrected amplitude signal with a reference amplitude signal to generate an amplitude error signal; integrator means for integrating said amplitude error signals to generate a fuel quantity correction signal for each engine cylinder; fuel control computer means for generating a fuel quantity signal for each engine cylinder in response to detected engine parameters; and second sum means for summing said fuel quantity signals with said fuel quantity correction signals to change the quantity of fuel delivered to the engine tending to equalize the amplitude of the torque impulses generated by the individual engine cylinder.
