摘要： PROBLEM TO BE SOLVED: To control an internal combustion engine mounted with a variable turbo-supercharger and an EGR (Exhaust Gas Recirculation) device while suppressing the undershooting/overshooting of an EGR rate or an EGR amount during finishing acceleration to avoid the temporary worsening of exhaust gas.
SOLUTION: In a target value lowering period when a target value r
2 for intake pipe pressure y
2 falls down, cylinder pressure lowers accompanied by the reduction of a fuel injection amount to gradually reduce an output of an exhaust turbo supercharger. In such a circumstance that the intake pipe pressure y
2 naturally lowers toward the target value r
2 , deviation in the intake pipe pressure given to a servo controller 51 is fixed to be zero. Thus, there arises no risk that the servo controller 51 abruptly operates the variable nozzle of the supercharger, thus avoiding the undershooting/overshooting of the EGR rate y

摘要翻译：要解决的问题：为了控制安装有可变涡轮增压器和EGR（排气再循环）装置的内燃机，同时在精加工期间抑制EGR率或EGR量的下冲/过冲，以避免废气临时恶化。
解决方案：当进气管压力y 2 的目标值r 2 的目标值降低期间下降时，气缸压力降低伴随着燃料的减少喷射量逐渐减小排气涡轮增压器的输出。在进气管压力y 2 自然降低到目标值r 2 的情况下，给伺服控制器51的进气管压力的偏差固定为零。因此，不存在伺服控制器51突然操作增压器的可变喷嘴的风险，从而避免了EGR率y 1 的下冲/过冲。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To avoid, in an EGR control of an EGR device associated with an internal combustion engine, a temporary drop of a supercharging pressure or an EGR rate at a timing of transition from a negative pressure range to a supercharging range.
