Abstract:
The control device controls an internal combustion engine comprising a fuel injector  31.  The control device comprises an injection control part controlling fuel injection from the fuel injector. The injection control part controls the fuel injections so as to perform a plurality of pre-injections and a main injection and so that the pre-injected fuel is burned by compression self-ignition after the start of main injection. The injection control part controls the fuel injector so as to perform the pre-injections and main injection at basic injection timings during steady operation, and performs correction control so as to correct the injection timings from the basic injection timings during transient operation. In correction control, the larger a crank angle from TDC of the injection timings of the different injections before correction, the greater the amounts of correction of the injection timings of the injections.

Claim (Index 1):
A control device of an internal combustion engine for controlling an internal combustion engine comprising a fuel injector directly injecting fuel into a combustion chamber, the control device of an internal combustion engine comprises an injection control part controlling fuel injection from the fuel injector,\n wherein the injection control part is configured to control fuel injection from the fuel injector so that the fuel injector performs pre-injection a plurality of times, then performs main injection and so that after starting the main injection, at least part of a premixed gas formed by the pre-injections burns by compression self-ignition, the injection control part is configured to control the fuel injector so as to perform the pre-injections and the main injection at basic injection timings calculated based on an engine operation state when the internal combustion engine is in the middle of steady operation, and when the internal combustion engine is in the middle of transient operation, the injection control part is configured to perform correction control correcting injection timings of the main injection and the pre-injections from the basic injection timings with respect to the time when the internal combustion engine is in the middle of steady operation, and, in the correction control, the larger the crank angles from. TDC of the injection timings of the injections before correction, the larger the amounts of correction of the injection timings of the injections.
