Abstract
Cylinder to cylinder variation in developed cylinder torque is suppressed by correcting ignition timings for the individual cylinders or by correcting fuel injection amounts allocated to the individual cylinders. Amounts of correction to be made to the individual ignition timings or fuel injection amounts are determined as results of comparison of individual cylinder pressure averages with a multiple cylinder pressure average that is an average of the individual cylinder pressure averages.
