    • A control system used with an engine determines a fuel injection timing according to a detected engine operating condition and fuel injection is executed through a fuel injection valve. The target ignition timings of the fuel are set according to the detected engine operating condition and stored in a memory. An ignition delay of the actual ignition timing relative to the target ignition timing and a cetane number of the fuel are calculated. Control values of the recirculation amount of exhaust gases are set according to the detected engine operating condition and stored in the memory. The stored control value is retrieved and the recirculation amount of exhaust gases is controlled using the retrieved control value. A correction amount of the recirculation amount of exhaust gases is calculated according to the estimated cetane number and the recirculation amount of exhaust gases is controlled using the corrected control value.
    • 与发动机一起使用的控制系统根据检测到的发动机工况确定燃料喷射正时,并且通过燃料喷射阀执行燃料喷射。 燃料的目标点火正时根据检测到的发动机工作条件设定并存储在存储器中。 计算实际点火正时相对于目标点火正时的点火延迟和燃料的十六烷值。 根据检测到的发动机工况设定废气再循环量的控制值并存储在存储器中。 所存储的控制值被检索并且使用所检索的控制值来控制废气的再循环量。 根据估计的十六烷值计算废气再循环量的校正量,并且使用校正的控制值来控制废气的再循环量。

    • A control system for an internal combustion engine having fuel injection valves provided in a combustion chamber and an exhaust gas recirculation mechanism. Target maximum cylinder pressure change rates are set according to the operating condition of the engine. The maximum change rate of the detected cylinder pressure and a fuel injection timing correction amount are calculated wherein a difference between the calculated maximum change rate and the target maximum cylinder pressure change rate decreases. The fuel injection timing is corrected with the fuel injection timing correction amount. The recirculation amount of exhaust gases is controlled using the calculated control value. A correction amount of the exhaust gas recirculation amount is calculated when the fuel injection timing correction amount exceeds a predetermined amount. The exhaust gas recirculation amount is controlled using the control value corrected with the correction amount of the exhaust gas recirculating amount.
    • 一种用于内燃机的控制系统,其具有设置在燃烧室中的燃料喷射阀和排气再循环机构。 目标最大气缸压力变化率根据发动机的运行状况设定。 计算检测到的气缸压力和燃料喷射正时校正量的最大变化率,其中计算的最大变化率和目标最大气缸压力变化率之间的差减小。 利用燃料喷射正时校正量校正燃料喷射正时。 使用计算出的控制值来控制废气的再循环量。 当燃料喷射正时校正量超过预定量时,计算排气再循环量的校正量。 使用利用废气再循环量的校正量校正的控制值来控制废气再循环量。
