Title: (ZH) 内燃机的控制装置
Abstract: front page image
(ZH)

本发明涉及执行排气再循环控制的内燃机的控制装置,所述排气再循环控制中,根据被设定为使检测空燃比(AFd)与推定空燃比(AFe)一致的目标排气再循环量(TRegr)来控制排气再循环装置(50、52)的工作状态。当实际目标排气再循环量的变化量相对于基准排气再循环量(Regrb)的设定所使用的基准排气再循环量设定参数(Q)的变化量之比(Rtregr)的符号与参照目标排气再循环量的变化量相对于基准排气再循环量设定参数的变化量之比的符号相反时,禁止执行基于瞬时修正值(KT)算出学习修正值(KGn)的学习功能,所述瞬时修正值(KT)是对当前的目标排气再循环量进行修正以使得空燃比偏差(Raf)变为零的修正值。
