Abstract:
As a compression-ignition direct-injection engine combustion controller, a program for detecting ignition timing of a main injection Mn (main ignition timing), a program for correcting a command value of main injection execution timing in a direction to the side where a detection value is converged within a predetermined range, a program for determining whether or not the corrected command value is within a predetermined range, and a program for, when it is determined that the command value is not within the range, correcting a command value related to an injection amount of a pilot injection Pt based on whether or not the command value is on a delay side or an advance side of the range.
