摘要

PPROBLEM TO BE SOLVED: To more efficiently adapt a correction gain for correcting a fuel injection parameter in transient operation. PSOLUTION: An engine rotation speed is set to form the boundary of a rotation speed range for achieving desired combustion by correcting main fuel injection timing tm in the transient operation without correcting a secondary fuel injection amount Qs and a fuel interval int which is the length of an interval between secondary fuel injection and main fuel injection, and for an engine rotation speed higher than the boundary rotation speed, only the correction gain for correcting the main fuel injection time tm in the transient operation is adapted (S202, S203, S206).

要解决的问题：在过渡运行中更有效地调整校正增益以校正燃油喷射参数。

解决方案：设置发动机转速以形成转速范围的边界，以通过在过渡操作中校正主燃料喷射正时tm来实现所需燃烧，而无需校正二次燃料喷射量Qs和燃料间隔int二次燃料喷射和主燃料喷射之间的间隔的长度，并且对于高于边界转速的发动机转速，仅适应在过渡运行中用于校正主燃料喷射时间tm的校正增益（S202，S203， S206）。
