摘要：Problem to be solved: to suppress the change of combustion noise. A fuelinjection control unit for injecting at least one primary fuel and a secondary fuel
sequentially from the fuel injection valve 20 is injected in such a manner that the cylinderinternal pressure rise rate pattern is two Yamagata in the combustion chamber 11 in the
combustion chamber In this case, there is provided an intake device control unit forcontrolling the intake device in such a manner that the oxygen density in the combustionchamber is higher than that in the combustion chamber.The fuel injection control part issuch that the second peak value of the second peak of the cylinder pressure rise ratepattern formed by the second heat generation is larger than the first peak value of thefirst peak of the cylinder pressure rise rate pattern formed by the first heat generation,and the engine is high when the engine load is high The injection timing and injectionamount of the primary fuel and the secondary fuel are set so that the peak differenceobtained by subtracting the first peak value from the second peak value becomes largerthan when the load is low.
