<p>PROBLEM TO BE SOLVED: To surely suppress increase in combustion noise in deceleration to an operation condition where an inside EGR rate of a compression self-ignition combustion region is high.SOLUTION: A control device of a direct injection engine includes a fuel injection device 15 capable of directly injecting fuel into a combustion chamber 11, and make an injection amount injected by the fuel injection device 15 smaller than an original injection amount corresponding to a second operation condition after deceleration, in deceleration of shifting from a first condition where an engine load is higher than a predetermined load to the second condition where the engine load is lower than the predetermined load, a hot EGR rate is higher than that in the first operation condition, and compression self-ignition is executed.</p> |
