    • PROBLEM TO BE SOLVED: To provide an internal combustion engine equipped with a starter capable of realizing stable combustion pressure for a long time, when the combustion pressure obtained by combusting fuel supplied at the time of stop of the engine is used for start of the engine.
      SOLUTION: An ECU detects engine speed NE at the time of an expansion stroke accompanied by combustion pressure immediately after start of the engine, and determines whether or not the detected engine speed NE is within a range from a lower limit value NE1 of a predetermined reference engine speed to the upper limit value NE2. When the engine speed NE is within this range, since correction of fuel supply amount (injection amount) is unnecessary, the ECU completes this determination control. Meanwhile, when the engine speed NE is out of this range, since correction of the fuel supply amount is necessary, the ECU calculates correction amount. When performing engine stop control next time, the ECU corrects the fuel supply amount supplied to inside of a fuel chamber.

    • 要解决的问题:为了提供配备有能够长时间实现稳定的燃烧压力的起动器的内燃机,当通过燃烧在发动机停止时供给的燃料获得的燃烧压力用于起动时 的发动机。 解决方案:ECU在发动机起动之后伴随着燃烧压力的膨胀行程时检测发动机转速NE,并且确定检测到的发动机转速NE是否在从下限值NE1开始的范围内 将预定的基准发动机转速设定为上限值NE2。 当发动机转速NE在该范围内时,由于不需要燃料供给量(喷射量)的校正,ECU完成该判定控制。 同时,当发动机转速NE在该范围之外时,由于需要校正燃料供给量,所以ECU计算校正量。 在下一次执行发动机停止控制时,ECU校正供应到燃料室内部的燃料供给量。 版权所有(C)2005,JPO&NCIPI
