Abstract
A fuel distribution control system for an internal combustion engine including means for detecting the instantaneous rotational velocity of the engine's crankshaft to generate a torque impulse amplitude signal and a phase angle signal, an amplitude correction circuit for correcting the torque impulse amplitude signal as a function of the phase angle signal, means for generating an amplitude error signal for each corrected torque impulse, and means for accumulating said amplitude error signals to generate individual fuel correction signals for each engine cylinder. The fuel correction signals are added to the fuel quantity signals generated by a fuel control computer in response to the operational parameters of the engine and a fuel delivery device responds to the combined fuel quantity and fuel correction signals to deliver a quantity of fuel to each engine cylinder tending to equalize the torque contribution of each cylinder to the total output torque of the engine.
