Abstract: <P>PROBLEM TO BE SOLVED: To improve the learning accuracy in the pilot learning control by eliminating any dispersion of the inclination of the multi-injection period characteristic to the multi-injection on one pressure level.  <P>SOLUTION: When the injection dispersion to the pilot injection period or the secular degradation of an injector is present, the inclination of the Tq-Q characteristic is dispersed as shown in a Tq-Q map by a broken line.
