CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE

摘要

A control apparatus for center position control of a geometric center of the area under a heat release rate curve over crank angle (610), wherein a control member runs an ignition acceleration procedure (640) when the engine satisfies at least one of specific conditions (630) during an exhaust gas recirculation (620) under the center position control. The ignition acceleration procedure (640) is to inject more fuel for a pilot injection than a base amount determined in accordance with the center position control (610). The specific conditions (630) include: a condition that an engine load is less than a threshold value, and a condition that an engine rotational speed is less than a threshold value.
