    摘要： An engine (10) is a cylinder injection engine, and includes an injector (21) that directly injects a fuel into a combustion chamber (23), and an ignition plug (34) that generates an ignition spark in the combustion chamber (23). An ECU (40) performs multiple first injections to each produce an air-fuel mixture of a lean air-fuel ratio in the combustion chamber (23) before an ignition in one combustion cycle of the engine, and performs a second injection to produce an air-fuel mixture of a rich air-fuel ratio in the combustion chamber (23) before the ignition and after the first injection. In particular, the ECU implements the multiple first injections in such a manner that the first injection implemented early among the multiple first injections produces an air-fuel mixture leaner than that of the first injection implemented subsequently. The ECU implements the second injection only once immediately before an ignition timing.

    摘要： A fuel injection valve is for injecting fuel to cause combustion in an internal combustion engine. An injection rate adjuster is for adjusting an injection rate of the fuel injected by the fuel injection valve. A control device for the internal combustion engine includes a signal generator, and an outputter. The signal generator generates a command signal to cause the injection rate adjuster to adjust the injection rate based on a parameter, which is to estimate an internal EGR amount in which a part of exhaust gas remains in a cylinder. The outputter outputs the command signal to the injection rate adjuster.
