Abstract: PROBLEM TO BE SOLVED: To provide a technology capable of stably forming a homogeneous pre-air/fuel mixture in a compression ignition internal combustion engine.
SOLUTION: In this method of controlling the fuel injection of the compression ignition internal combustion engine, the pre-air/fuel mixture is formed in a combustion chamber by performing a first fuel injection from a center injector (main fuel injection valve) 6 near the intake stroke top dead center and a second fuel injection from a side injector (auxiliary fuel injection valve) 7 between the first and the intermediate positions of a compression stroke. An area where a first injection fuel is deviated is estimated on the basis of a first injection fuel amount and a common rail pressure. When the first injection fuel is estimated to be deviated to the center of the combustion chamber 40, a second target fuel injection timing Tside is advanced to deviate a second injection fuel to the peripheral edge of the combustion chamber. When the first injection fuel is estimated to be deviated to the peripheral edge of the combustion chamber, the second target fuel injection timing Tside is retarded to deviate the second injection fuel to the center of the combustion chamber.
